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 bromide is the bromide salt of radium, with the formula RaBr 2.It is produced during the process of separating radium from uranium ore.This inorganic compound was discovered by Pierre and Marie Curie in 1898, and the discovery sparked a huge interest in radiochemistry and radiotherapy.
Soon after the discovery of radium in 1898 by Pierre and Marie Curie, there was speculation in whether the radiation could be used for therapy in the same way as that from x-rays. The physiological effect of radium was first observed in 1900 by Otto Walkhoff , [ 23 ] and later confirmed by what famously known as the "Becquerel burn".
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.
Marie Curie's birthplace, 16 Freta Street, Warsaw, Poland. Maria Salomea Skłodowska-Curie [a] (Polish: [ˈmarja salɔˈmɛa skwɔˈdɔfska kʲiˈri] ⓘ; née Skłodowska; 7 November 1867 – 4 July 1934), known simply as Marie Curie (/ ˈ k j ʊər i / KURE-ee; [1] French: [maʁi kyʁi]), was a Polish and naturalised-French physicist and chemist who conducted pioneering research on ...
In the years that followed, radioactivity was extensively investigated, notably by Marie Curie, a Polish physicist whose maiden name was Sklodowska, Pierre Curie, Ernest Rutherford and others. By the turn of the century, physicists had also discovered three types of radiation emanating from atoms, which they named alpha, beta, and gamma radiation.
At the same time, Pierre and Marie Curie discovered the radioactive polonium and radium later used to treat cancer. The genetic effects of radiation, including the effects on cancer risk, were recognized much later. In 1927 Hermann Joseph Muller published research showing genetic effects, and in 1946 was awarded the Nobel prize for his findings.
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.
