Radioactivity of Geological Materials

Primeval elements with long half-lives such as potassium (40K), thorium (232Th), and uranium (235U, 238U produce elements with shorter half-lives as part of the decay process. Other primeval elements such as calcium (48Ca), vanadium (50V), and nickel (58Ni) are either … Continue reading

Radioactivity

Some elements are naturally radioactive, releasing alpha particles, beta particles, or gamma radiation as they decay to more stable elements. The decay in a fixed period of time is proportional to the number of unstable atoms, with exponential decay dictating … Continue reading
