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.
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.

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 ]
Radium was discovered by Marie Skłodowska-Curie and her husband Pierre Curie on 21 December 1898 in a uraninite (pitchblende) sample from Jáchymov. [32] While studying the mineral earlier, the Curies removed uranium from it and found that the remaining material was still radioactive.
In 1898, Marie and Pierre Curie discovered a strongly radioactive substance in pitchblende and determined that it was a new element; it was one of the first radioactive elements discovered. Having identified it as such, they named the element polonium after Marie's home country, Poland.
The element was named after Marie Curie and her husband Pierre Curie, who are known for discovering radium and for their work in radioactivity. It followed the example of gadolinium, a lanthanide element above curium in the periodic table, which was named after the explorer of rare-earth elements Johan Gadolin: [13]
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.
