What is Curie answer?
Answer: Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive.
Who won the Nobel Prize with the Curies?
Marie Curie
The Nobel Prize in Chemistry 1911 was awarded to Marie Curie, née Sklodowska “in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element.”
Why did Marie Curie get the Nobel Prize in Physics?
Working with her husband, Pierre Curie, Marie Curie discovered polonium and radium in 1898. In 1903 they won the Nobel Prize for Physics for discovering radioactivity. In 1911 she won the Nobel Prize for Chemistry for isolating pure radium.
What did Becquerel and the Curies do?
The French Physicist, Henri Becquerel, discovered the phenomenon of radioactivity. He shared the Nobel Prize in Physics with Marie Curie and Pierre Curie (Marie’s husband) in 1903 for their work in radioactivity . Madame Curie and her husband coined the term radioactivity.
What do you mean by 1 curie?
One curie (1 Ci) is equal to 3.7 × 1010 radioactive decays per second, which is roughly the amount of decays that occur in 1 gram of radium per second and is 3.7 × 1010 becquerels (Bq). In 1975 the becquerel replaced the curie as the official radiation unit in the International System of Units (SI).
Which unit is curie?
The curie (symbol Ci) was the unit for radioactive decay in the cgs system. One curie was defined as the radioactivity of one gram of pure radium-226; this is equivalent to 3.7 x 1010 decays per second. It was officially replaced by the becquerel in 1975.
Who is the first female Nobel laureate?
This list of female laureates includes Marie Curie, who was the first woman to win the Nobel Prize. Curie actually obtained the Prize twice, receiving it in Physics in 1903 and then in Chemistry in 1911.
Who was first person to win two Nobel prizes?
The couple later shared the 1903 Nobel Prize in Physics. Marie was widowed in 1906, but continued the couple’s work and went on to become the first person ever to be awarded two Nobel Prizes.
What two Nobel prizes has Marie Curie awarded?
Together with her husband, she was awarded half of the Nobel Prize for Physics in 1903, for their study into the spontaneous radiation discovered by Becquerel, who was awarded the other half of the Prize. In 1911 she received a second Nobel Prize, this time in Chemistry, in recognition of her work in radioactivity.
How many curies of radiation is safe?
Adult: 5,000 Millirems. The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is “as low as reasonably achievable; however, not to exceed 5,000 millirems” above the 300+ millirems of natural sources of radiation and any medical radiation.
Why did Becquerel and Curie win the Nobel Prize?
The discoveries and research of Becquerel and of M. and Mme. Curie are closely bound up with each other; the latter were of course co-workers. The Royal Academy of Sciences did not think it right to distinguish between these eminent scientists, when it came to awarding the discovery of spontaneous radioactivity a Nobel Prize.
When did Marie Curie win her second Nobel Prize?
Little could they have imagined that not only would Marie go on to win a second Nobel in chemistry in 1911 — the first person ever to receive the prize twice — but Irène and her husband, Frédéric Joliot, would take home their own Nobel in chemistry in 1936.
How did Marie Curie get recognition for her work?
If not for the intervention of a member of the nominating committee, Swedish mathematician Magnus Goesta Mittag-Leffler, Marie might have been denied recognition for her work. But Mittag-Leffler, an advocate of women scientists, wrote Pierre advising him of the situation.
Why was radioactivity not awarded a Nobel Prize?
The Royal Academy of Sciences did not think it right to distinguish between these eminent scientists, when it came to awarding the discovery of spontaneous radioactivity a Nobel Prize.
