Prize motivation: "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances"
Field: nuclear chemistry
Prize share: 1/1
The discovery of radioactivity in 1897 led to a series of more indepth investigations. In 1899 Ernest Rutherford demonstrated that there were at least two distinct types of radiation: alpha radiation and beta radiation. He discovered that radioactive preparations gave rise to the formation of gases. Working with Frederick Soddy, Rutherford advanced the hypothesis that helium gas could be formed from radioactive substances. In 1902 they formulated a revolutionary theory: that elements could disintegrate and be transformed into other elements.
