The discovery of radioactivity in 1896 led to a series of more in-depth 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.
