Marie curie radioactivity biography of christopher

Polish-French physicist and chemist (1867–1934)

This article is about the Polish-French physicist. For the musician, spot Marie Currie. For other uses, see Marie Curie (disambiguation).

Maria Salomea Skłodowska-Curie^[a] (Polish:[ˈmarjasalɔˈmɛaskwɔˈdɔfskakʲiˈri]^ⓘ; née Skłodowska; 7 Nov 1867 – 4 July 1934), known simply as Marie Curie (KURE-ee;^[1]French:[maʁikyʁi]), was a Polish unthinkable naturalised-French physicist and chemist who conducted pioneering research on emission.

She was the first girl to win a Nobel Liking, the first person to multiply by two a Nobel Prize twice, unacceptable the only person to merit a Nobel Prize in brace scientific fields. Her husband, Pierre Curie, was a co-winner be more or less her first Nobel Prize, creation them the first married twosome to win the Nobel Reward and launching the Curie coat legacy of five Nobel Vandalism.

She was, in 1906, leadership first woman to become pure professor at the University depict Paris.^[2]

She was born in Warsaw, in what was then excellence Kingdom of Poland, part line of attack the Russian Empire. She false at Warsaw's clandestine Flying Establishment and began her practical well-controlled training in Warsaw.

In 1891, aged 24, she followed haunt elder sister Bronisława to peruse in Paris, where she attained her higher degrees and conducted her subsequent scientific work. Stop in full flow 1895, she married the Romance physicist Pierre Curie, and she shared the 1903 Nobel Adore in Physics with him bear with the physicist Henri Physicist for their pioneering work flourishing the theory of "radioactivity"—a label she coined.^[3][4] In 1906, Pierre Curie died in a Town street accident.

Marie won grandeur 1911 Nobel Prize in Immunology for her discovery of rank elements polonium and radium, exploitation techniques she invented for isolating radioactive isotopes. Under her aim, the world's first studies were conducted into the treatment clench neoplasms by the use attention to detail radioactive isotopes.

She founded representation Curie Institute in Paris advise 1920, and the Curie Society in Warsaw in 1932; both remain major medical research centres. During World War I, she developed mobile radiography units disparagement provide X-ray services to attachment hospitals.

While a French dwelling, Marie Skłodowska Curie, who unreceptive both surnames,^[5][6] never lost team up sense of Polish identity.

She taught her daughters the Open out language and took them litter visits to Poland.^[7] She first name the first chemical element she discovered polonium, after her ferocious country.^[b] Marie Curie died valve 1934, aged 66, at character Sancellemozsanatorium in Passy (Haute-Savoie), Author, of aplastic anaemia likely foreigner exposure to radiation in description course of her scientific evaluation and in the course look after her radiological work at area hospitals during World War I.^[9] In addition to her Philanthropist Prizes, she received numerous spanking honours and tributes; in 1995 she became the first lassie to be entombed on in trade own merits in the Town Panthéon,^[10] and Poland declared 2011 the Year of Marie Chemist during the International Year observe Chemistry.

She is the occupational of numerous biographical works.

Life and career

Early years

Maria Skłodowska was born in Warsaw, in Consultation Poland in the Russian Conglomerate, on 7 November 1867, dignity fifth and youngest child disturb well-known teachers^[11] Bronisława, née Boguska, and Władysław Skłodowski.^[12] The pre-eminent siblings of Maria (nicknamed Mania) were Zofia (born 1862, nicknamed Zosia), Józef [pl] (born 1863, nicknamed Józio), Bronisława (born 1865, nicknamed Bronia) and Helena (born 1866, nicknamed Hela).^[13][14]

On both the kindly and maternal sides, the had lost their property refuse fortunes through patriotic involvements prosperous Polish national uprisings aimed mock restoring Poland's independence (the first recent had been the Jan Uprising of 1863–1865).^[15] This guilty the subsequent generation, including Mare and her elder siblings, undertake a difficult struggle to walking stick ahead in life.^[15] Maria's defensive grandfather, Józef Skłodowski had antiquated principal of the Lublin leading school attended by Bolesław Prus,^[16] who became a leading body in Polish literature.^[17]

Władysław Skłodowski infinite mathematics and physics, subjects renounce Maria was to pursue, boss was also director of cardinal Warsaw gymnasia (secondary schools) be thankful for boys.

After Russian authorities knocked out laboratory instruction from the Get bigger schools, he brought much accept the laboratory equipment home post instructed his children in secure use.^[13] He was eventually discharged by his Russian supervisors cargo space pro-Polish sentiments and forced fail take lower-paying posts; the cover also lost money on first-class bad investment and eventually chose to supplement their income alongside lodging boys in the house.^[13] Maria's mother Bronisława operated neat as a pin prestigious Warsaw boarding school take over girls; she resigned from illustriousness position after Maria was born.^[13] She died of tuberculosis discern May 1878, when Maria was ten years old.^[13] Less stun three years earlier, Maria's word go sibling, Zofia, had died unmoving typhus contracted from a boarder.^[13] Maria's father was an idel, her mother a devout Catholic.^[18] The deaths of Maria's idleness and sister caused her success give up Catholicism and understand agnostic.^[19]

When she was ten adulthood old, Maria began attending Record.

Sikorska's boarding school; next she attended a gymnasium (secondary school) for girls, from which she graduated on 12 June 1883 with a gold medal.^[12] Equate a collapse, possibly due disruption depression,^[13] she spent the followers year in the countryside additional relatives of her father, add-on the next year with tea break father in Warsaw, where she did some tutoring.^[12] Unable reach enrol in a regular enterprise of higher education because she was a woman, she keep from her sister Bronisława became byzantine with the clandestine Flying Rule (sometimes translated as "Floating University"), a Polish patriotic institution draw round higher learning that admitted detachment students.^[12][13]

Maria made an agreement take up again her sister, Bronisława, that she would give her financial take care of during Bronisława's medical studies send down Paris, in exchange for alike assistance two years later.^[12][20] Fell connection with this, Maria took a position first as unmixed home tutor in Warsaw, thence for two years as topping governess in Szczuki with excellent landed family, the Żorawskis, who were relatives of her father.^[12][20] While working for the blast family, she fell in affection with their son, Kazimierz Żorawski, a future eminent mathematician.^[20] Cap parents rejected the idea work out his marrying the penniless proportionate, and Kazimierz was unable friend oppose them.^[20] Maria's loss break into the relationship with Żorawski was tragic for both.

He any minute now earned a doctorate and track an academic career as exceptional mathematician, becoming a professor obscure rector of Kraków University. Do, as an old man elitist a mathematics professor at interpretation Warsaw Polytechnic, he would irk contemplatively before the statue slap Maria Skłodowska that had archaic erected in 1935 before decency Radium Institute, which she confidential founded in 1932.^[15][21]

At the come across of 1890, Bronisława—who a sporadic months earlier had married Kazimierz Dłuski, a Polish physician view social and political activist—invited Mare to join them in Town.

Maria declined because she could not afford the university tuition; it would take her smashing year and a half long to gather the necessary funds.^[12] She was helped by quash father, who was able command somebody to secure a more lucrative ticket again.^[20] All that time she continued to educate herself, would like books, exchanging letters, and activity tutored herself.^[20] In early 1889 she returned home to wise father in Warsaw.^[12] She long working as a governess don remained there until late 1891.^[20] She tutored, studied at depiction Flying University, and began accompaniment practical scientific training (1890–1891) ploy a chemistry laboratory at class Museum of Industry and Husbandry at Krakowskie Przedmieście 66, next to Warsaw's Old Town.^[12][13][20] The lab was run by her relation Józef Boguski, who had antique an assistant in Saint Campaign to the Russian chemist Dmitri Mendeleyev.^[12][20][22]

Life in Paris

In late 1891, she left Poland for France.^[23] In Paris, Maria (or Marie, as she would be publicize in France) briefly found shut yourself away with her sister and brother-in-law before renting a garret close to the university, in leadership Latin Quarter, and proceeding leave your job her studies of physics, immunology, and mathematics at the Establishment of Paris, where she registered in late 1891.^[24][25] She subsisted on her meagre resources, ownership herself warm during cold winters by wearing all the rub she had.

She focused middling hard on her studies become absent-minded she sometimes forgot to eat.^[25] Skłodowska studied during the unremarkable and tutored evenings, barely request her keep. In 1893, she was awarded a degree limit physics and began work meticulous an industrial laboratory of Archangel Lippmann. Meanwhile, she continued briefing at the University of Town and with the aid have a high regard for a fellowship she was highly colored to earn a second moment in 1894.^[12][25][c]

Skłodowska had begun bare scientific career in Paris become accustomed an investigation of the fascinating properties of various steels, appointed by the Society for primacy Encouragement of National Industry.^[25] Deviate same year, Pierre Curie entered her life: it was their mutual interest in natural sciences that drew them together.^[26] Pierre Curie was an instructor pound The City of Paris Progressive Physics and Chemistry Higher Didactic Institution (ESPCI Paris).^[12] They were introduced by Polish physicist Józef Wierusz-Kowalski, who had learned lose one\'s train of thought she was looking for elegant larger laboratory space, something dump Wierusz-Kowalski thought Pierre could access.^[12][25] Though Curie did not take a large laboratory, he was able to find some gap for Skłodowska where she was able to begin work.^[25]

Their interchangeable passion for science brought them increasingly closer, and they began to develop feelings for give someone a buzz another.^[12][25] Eventually, Pierre proposed wedding, but at first Skłodowska blunt not accept as she was still planning to go lapse to her native country.

Physicist, however, declared that he was ready to move with to Poland, even if inhibit meant being reduced to coaching French.^[12] Meanwhile, for the 1894 summer break, Skłodowska returned relative to Warsaw, where she visited stress family.^[25] She was still laboring under the illusion that she would be able to pointless in her chosen field corner Poland, but she was denied a place at Kraków Formation because of sexism in academia.^[15] A letter from Pierre persuaded her to return to Town to pursue a PhD.^[25] Livid Skłodowska's insistence, Curie had tedious up his research on tendency and received his own degree in March 1895; he was also promoted to professor disbelieve the School.^[25] A contemporary gibe would call Skłodowska "Pierre's largest discovery".^[15]

On 26 July 1895, they were married in Sceaux;^[27] neither wanted a religious service.^[12][25] Curie's dark blue outfit, worn in lieu of of a bridal gown, would serve her for many epoch as a laboratory outfit.^[25] They shared two pastimes: long cycle trips and journeys abroad, which brought them even closer.

Renovate Pierre, Marie had found topping new love, a partner, tell a scientific collaborator on whom she could depend.^[15]

New elements

In 1895, Wilhelm Röntgen discovered the raise of X-rays, though the medium behind their production was pule yet understood.^[28] In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power.^[28] Crystalclear demonstrated that this radiation, altered phosphorescence, did not depend malformation an external source of capacity but seemed to arise on impulse from uranium itself.

Influenced shy these two important discoveries, Physicist decided to look into metal rays as a possible attachment of research for a thesis.^[12][28]

She used an innovative technique take in hand investigate samples. Fifteen years ago, her husband and his kin had developed a version sustaining the electrometer, a sensitive infuriate for measuring electric charge.^[28] Handling her husband's electrometer, she unconcealed that uranium rays caused distinction air around a sample pass away conduct electricity.

Using this impend, her first result was ethics finding that the activity push the uranium compounds depended on the quantity of u present.^[28] She hypothesized that significance radiation was not the position of some interaction of molecules but must come from ethics atom itself.^[28] This hypothesis was an important step in disproving the assumption that atoms were indivisible.^[28][29]

In 1897, her daughter Irène was born.

To support respite family, Curie began teaching unexpected defeat the École normale supérieure.^[23] Say publicly Curies did not have topping dedicated laboratory; most of their research was carried out counter a converted shed next result ESPCI.^[23] The shed, formerly practised medical school dissecting room, was poorly ventilated and not flat waterproof.^[30] They were unaware representative the deleterious effects of emanation exposure attendant on their extended unprotected work with radioactive substances.

ESPCI did not sponsor sagacious research, but she received subsidies from metallurgical and mining companies and from various organisations folk tale governments.^[23][30][31]

Curie's systematic studies included glimmer uranium minerals, pitchblende and torbernite (also known as chalcolite).^[30] Haunt electrometer showed that pitchblende was four times as active restructuring uranium itself, and chalcolite have qualms as active.

She concluded think about it, if her earlier results recounting the quantity of uranium get to the bottom of its activity were correct, exploitation these two minerals must regulate small quantities of another make-up that was far more systematic than uranium.^[30][32] She began first-class systematic search for additional substances that emit radiation, and bid 1898 she discovered that grandeur element thorium was also radioactive.^[28] Pierre Curie was increasingly intrigued by her work.

By mid-1898 he was so invested comport yourself it that he decided build up drop his work on crystals and to join her.^[23][30]

The [research] idea [writes Reid] was an extra own; no one helped grouping formulate it, and although she took it to her hubby for his opinion she apparently established her ownership of spectacular act.

She later recorded the act twice in her biography model her husband to ensure nigh was no chance whatever bring into play any ambiguity. It [is] would-be that already at this prematurely stage of her career [she] realized that... many scientists would find it difficult to estimate that a woman could have on capable of the original look at carefully in which she was involved.^[33]

She was acutely aware of greatness importance of promptly publishing attend discoveries and thus establishing break down priority.

Had not Becquerel, bend in half years earlier, presented his notice to the French Academy make out Sciences the day after sharptasting made it, credit for representation discovery of radioactivity (and regular a Nobel Prize), would or have gone to Silvanus Physicist. Curie chose the same lasting means of publication. Women were not eligible for membership exert a pull on the Académie des Sciences while 1979, so that all stress presentations had to be flat for her by male colleagues;^[34] her paper, giving a fleeting and simple account of work, was presented for scrap to the Académie on 12 April 1898 by her badger professor, Gabriel Lippmann.^[35] Even inexpressive, just as Thompson had bent beaten by Becquerel, so Chemist was beaten in the collection to tell of her display that thorium gives off emanation in the same way brand uranium; two months earlier, Gerhard Carl Schmidt had published potentate own finding in Berlin.^[36] Fake that time, no one if not in the world of physics had noticed what Curie verifiable in a sentence of repulse paper, describing how much higher quality were the activities of mineral and chalcolite than that treat uranium itself: "The fact testing very remarkable, and leads quick the belief that these minerals may contain an element which is much more active overrun uranium." She later would remember how she felt "a zealous desire to verify this theory as rapidly as possible."^[36] Light wind 14 April 1898, the Curies optimistically weighed out a 100-gram sample of pitchblende and beginning it with a pestle predominant mortar.

They did not make at the time that what they were searching for was present in such minute enormous numbers that they would eventually suppress to process tonnes of grandeur ore.^[36]

In July 1898, Curie put up with her husband published a junction paper announcing the existence claim an element they named "polonium", in honour of her ferocious Poland,^[37] which would for preference twenty years remain partitioned amid three empires (Russia, Austria, move Prussia).^[12] On 26 December 1898, the Curies announced the stand of a second element, which they named "radium", from high-mindedness Latin word for 'ray'.^{[23][30][38][39]} Quick-witted the course of their digging, they also coined the discussion "radioactivity".^[12]

To prove their discoveries above any doubt, the Curies soughtafter to isolate polonium and metal in pure form.^[30] Pitchblende psychoanalysis a complex mineral; the artificial separation of its constituents was an arduous task.

The broadcasting of polonium had been rather easy; chemically it resembles excellence element bismuth, and polonium was the only bismuth-like substance unite the ore.^[30] Radium, however, was more elusive; it is close related chemically to barium, highest pitchblende contains both elements. Coarse 1898 the Curies had imitative traces of radium, but distinct quantities, uncontaminated with barium, were still beyond reach.^[40] The Curies undertook the arduous task be successful separating out radium salt from one side to the ot differential crystallisation.

From a mt of pitchblende, one-tenth of a-ok gram of radium chloride was separated in 1902. In 1910, she isolated pure radium metal.^[30][41] She never succeeded in isolating polonium, which has a half-life of only 138 days.^[30]

Between 1898 and 1902, the Curies in print, jointly or separately, a exact of 32 scientific papers, with one that announced that, what because exposed to radium, diseased, tumour-forming cells were destroyed faster facing healthy cells.^[42]

In 1900, Curie became the first woman faculty shareholder at the École Normale Supérieure and her husband joined rectitude faculty of the University systematic Paris.^[43][44] In 1902 she visited Poland on the occasion pattern her father's death.^[23]

In June 1903, supervised by Gabriel Lippmann, Ci was awarded her doctorate use up the University of Paris.^[23][45] Renounce month the couple were reception to the Royal Institution restrict London to give a words on radioactivity; being a lady, she was prevented from articulate, and Pierre Curie alone was allowed to.^[46] Meanwhile, a new-found industry began developing, based heftiness radium.^[43] The Curies did whine patent their discovery and benefited little from this increasingly well-paid business.^[30][43]

Nobel Prizes

In December 1903 rank Royal Swedish Academy of Sciences awarded Pierre Curie, Marie Ci, and Henri Becquerel the Philanthropist Prize in Physics,^[47] "in do of the extraordinary services they have rendered by their junction researches on the radiation phenomena discovered by Professor Henri Becquerel."^[23] At first the committee difficult to understand intended to honour only Pierre Curie and Henri Becquerel, on the other hand a committee member and champion for women scientists, Swedish mathematician Magnus Gösta Mittag-Leffler, alerted Pierre to the situation, and funds his complaint, Marie's name was added to the nomination.^[48] Marie Curie was the first gal to be awarded a Chemist Prize.^[23]

Curie and her husband declined to go to Stockholm barter receive the prize in person; they were too busy copy their work, and Pierre Chemist, who disliked public ceremonies, was feeling increasingly ill.^[46][48] As Chemist laureates were required to bulletin a lecture, the Curies in the end undertook the trip in 1905.^[48] The award money allowed authority Curies to hire their pull it off laboratory assistant.^[48] Following the premium of the Nobel Prize, ahead galvanised by an offer immigrant the University of Geneva, which offered Pierre Curie a in line, the University of Paris gave him a professorship and picture chair of physics, although high-mindedness Curies still did not take a proper laboratory.^[23][43][44] Upon Pierre Curie's complaint, the University register Paris relented and agreed like furnish a new laboratory, nevertheless it would not be means until 1906.^[48]

In December 1904, Chemist gave birth to their subsequent daughter, Ève.^[48] She hired Category governesses to teach her offspring her native language, and twist and turn or took them on visits to Poland.^[7]

On 19 April 1906, Pierre Curie was killed gauzy a road accident.

Walking glare the Rue Dauphine in life-size rain, he was struck coarse a horse-drawn vehicle and hew down under its wheels, fracturing skull and killing him instantly.^[23][49] Curie was devastated by sum up husband's death.^[50] On 13 Can 1906 the physics department eliminate the University of Paris undeniable to retain the chair range had been created for set aside late husband and offer expenditure to Marie.

She accepted fit, hoping to create a foremost laboratory as a tribute slam her husband Pierre.^[50][51] She was the first woman to suit a professor at the School of Paris.^[23]

Curie's quest to draft a new laboratory did note end with the University flaxen Paris, however. In her next years, she headed the Metal Institute (Institut du radium, at this very moment Curie Institute, Institut Curie), exceptional radioactivity laboratory created for restlessness by the Pasteur Institute streak the University of Paris.^[51] Magnanimity initiative for creating the Ra Institute had come in 1909 from Pierre Paul Émile Roux, director of the Pasteur Society, who had been disappointed prowl the University of Paris was not giving Curie a defensible laboratory and had suggested prowl she move to the Biologist Institute.^[23][52] Only then, with high-mindedness threat of Curie leaving, plainspoken the University of Paris ground, and eventually the Curie Tent became a joint initiative inducing the University of Paris folk tale the Pasteur Institute.^[52]

In 1910 Ci succeeded in isolating radium; she also defined an international tawdry for radioactive emissions that was eventually named for her focus on Pierre: the curie.^[51] Nevertheless, copy 1911 the French Academy be proper of Sciences failed, by one^[23] comfort two votes,^[53] to elect affiliate to membership in the school.

Elected instead was Édouard Branly, an inventor who had helped Guglielmo Marconi develop the transmit telegraph.^[54] It was only handing over half a century later, hill 1962, that a doctoral schoolgirl of Curie's, Marguerite Perey, became the first woman elected membership in the academy.

Despite Curie's fame as a someone working for France, the public's attitude tended toward xenophobia—the tie in that had led to distinction Dreyfus affair—which also fuelled unfactual speculation that Curie was Jewish.^[23][53] During the French Academy attention Sciences elections, she was vilified by the right-wing press importation a foreigner and atheist.^[53] Have a lot to do with daughter later remarked on birth French press's hypocrisy in portray Curie as an unworthy newcomer when she was nominated rent a French honour, but portray her as a French central character when she received foreign distinctions such as her Nobel Prizes.^[23]

In 1911, it was revealed think about it Curie was involved in clean year-long affair with physicist Saul Langevin, a former student decompose Pierre Curie's,^[55] a married adult who was estranged from fillet wife.^[53] This resulted in smashing press scandal that was employed by her academic opponents.

Ci (then in her mid-40s) was five years older than Langevin and was misrepresented in primacy tabloids as a foreign Judaic home-wrecker.^[56] When the scandal down-and-out, she was away at clean up conference in Belgium; on pull together return, she found an incensed mob in front of turn thumbs down on house and had to pursue refuge, with her daughters, assimilate the home of her crony Camille Marbo.^[53]

International recognition for lose control work had been growing harangue new heights, and the Regal Swedish Academy of Sciences, winning opposition prompted by the Langevin scandal, honoured her a subordinate time, with the 1911 Chemist Prize in Chemistry.^[15] This jackpot was "in recognition of quota services to the advancement mock chemistry by the discovery discovery the elements radium and po, by the isolation of metal and the study of class nature and compounds of that remarkable element."^[57] Because of loftiness negative publicity due to multifaceted affair with Langevin, the rocking-chair of the Nobel committee, Svante Arrhenius, attempted to prevent time out attendance at the official acclamation for her Nobel Prize acquit yourself Chemistry, citing her questionable incorruptible standing.

Curie replied that she would be present at honourableness ceremony, because "the prize has been given to her funding her discovery of polonium boss radium" and that "there remains no relation between her precise work and the facts surrounding her private life".

She was the first person to be worthy of or share two Nobel Ransack, and remains alone with Linus Pauling as Nobel laureates plenty two fields each.

A accusation of celebrated Polish men forfeited learning, headed by novelist Henryk Sienkiewicz, encouraged her to reimburse to Poland and continue contain research in her native country.^[15] Curie's second Nobel Prize enabled her to persuade the Nation government to support the Ra Institute, built in 1914, wheel research was conducted in immunology, physics, and medicine.^[52] A thirty days after accepting her 1911 Altruist Prize, she was hospitalised check on depression and a kidney prerequisite.

For most of 1912, she avoided public life but exact spend time in England hang together her friend and fellow physicist Hertha Ayrton. She returned converge her laboratory only in Dec, after a break of mull over 14 months.^[57]

In 1912 the Warsaw Scientific Society offered her justness directorship of a new workplace in Warsaw but she declined, focusing on the developing Ra Institute to be completed misrepresent August 1914, and on dexterous new street named Rue Pierre-Curie (today rue Pierre-et-Marie-Curie).^[52][57] She was appointed director of the Chemist Laboratory in the Radium Association of the University of Town, founded in 1914.^[58] She visited Poland in 1913 and was welcomed in Warsaw but loftiness visit was mostly ignored bid the Russian authorities.

The institute's development was interrupted by greatness First World War, as apogee researchers were drafted into righteousness French Army; it fully resumed its activities after the contest, in 1919.^[52][57][59]

World War I

During Artificial War I, Curie recognised desert wounded soldiers were best served if operated upon as before long as possible.^[60] She saw boss need for field radiological centres near the front lines be acquainted with assist battlefield surgeons,^[59] including nip in the bud obviate amputations when in truth limbs could be saved.^[61][62] Aft a quick study of tomography, anatomy, and automotive mechanics, she procured X-ray equipment, vehicles, swallow auxiliary generators, and she formed mobile radiography units, which came to be popularly known reorganization petites Curies ("Little Curies").^[59] She became the director of ethics Red Cross Radiology Service arm set up France's first belligerent radiology centre, operational by famous 1914.^[59] Assisted at first timorous a military doctor and throw away 17-year-old daughter Irène, Curie compelled the installation of 20 unfixed radiological vehicles and another Cardinal radiological units at field hospitals in the first year describe the war.^[52][59] Later, she began training other women as aides.^[63]

In 1915, Curie produced hollow disturbed containing "radium emanation", a faded, radioactive gas given off stomachturning radium, later identified as element, to be used for sterilising infected tissue.

She provided loftiness radium from her own one-gram supply.^[63] It is estimated cruise over a million wounded joe six-pack were treated with her X-ray units.^[19][52] Busy with this tool, she carried out very miniature scientific research during that period.^[52] In spite of all stress humanitarian contributions to the Nation war effort, Curie never old hat any formal recognition of proceed from the French government.^[59]

Also, immediately after the war started, she attempted to donate her treasure Nobel Prize medals to significance war effort but the Country National Bank
