Emanation Radia

Natural sources of radioactivity

Having discovered the phenomenon of radioactivity, Rutherford, however, did not connect its discovered phenomena with a specific element. In his experiments, the scientist noticed the release of alpha particles when Uranium was bombarded with radioactive substances containing radium, Ra and actinium, Ac. This was convincingly confirmed by various experiments of scientists, and, first of all, by the works of the English physicist E. Atkins. They conducted experiments on the precipitation of radioactive substances from nitric acid and acetic acid solutions and found that the nature of these substances was different from the nature of most chemical elements. It was even more convincingly proven that radioactive substances can transform
