The curie (symbol Ci) is a non-SI unit of radioactivity originally defined in 1910. According to a notice in Nature at the time, it was to be named in honour of Pierre Curie, [1] but was considered at least by some to be in honour of Marie Skłodowska-Curie as well, [2] and is in later literature considered to be named for both. [3]
They experienced radiation sickness and Marie Curie died from radiation-induced aplastic anemia in 1934. Even now, all their papers from the 1890s, even her cookbooks, are radioactive. Their laboratory books are kept in special lead boxes and people who want to see them have to wear protective clothing. [43]
[23] [30] [38] [39] In the course of their research, they also coined the word "radioactivity". [12] Pierre and Marie Curie, c. 1903. To prove their discoveries beyond any doubt, the Curies sought to isolate polonium and radium in pure form. [30] Pitchblende is a complex mineral; the chemical separation of its constituents was an arduous task.
It was not until 1898 that Marie Curie-Skłodowska (1867-1934) and her husband Pierre Curie (1859-1906) discovered radium and created the concept of radioactivity. [84] Beginning in the fall of 1898, Marie Curie suffered from inflammation of the fingertips, the first known symptoms of radiation sickness.
Treatise on Radioactivity (French: Traité de Radioactivité) is a two-volume 1910 book written by the Polish scientist Marie Curie as a survey on the subject of radioactivity. [1] [2] [3] She was awarded her second Nobel Prize in the following year after the publication of the book. [4]
Following its discovery by Marie and Pierre Curie in 1898, radium (principally 226 Ra) has had a number of uses. In the early 20th century, when the hazards of radiation were not well-known, radium was commonly used in consumer items such as toothpaste and hair creams.
In 1906, Pierre Curie died in a Paris street accident. Marie won the 1911 Nobel Prize in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes. Under her direction, the world's first studies were conducted into the treatment of neoplasms by the use of radioactive isotopes.
Irène Joliot-Curie (French: [iʁɛn ʒɔljo kyʁi] ⓘ; née Curie; 12 September 1897 – 17 March 1956) was a French chemist and physicist who received the 1935 Nobel Prize in Chemistry with her husband, Frédéric Joliot-Curie, for their discovery of induced radioactivity.
