GROUNDWATER INFORMATION SHEET Radionuclides

Radium decays to form isotopes of radioactive radon and stable lead. Before the risks of radium exposure were understood, mixtures of light emitting radium salts and phosphors were widely used in luminescent paints for clock dials and gauges. Radon-222 Radon is a naturally occurring gas, and is a product of uranium decay.

Uranium Series - Radium Series - Nuclear Power

The uranium series, known also as radium series, is one of three classical radioactive series beginning with naturally occurring uranium-238.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. In case of uranium series, the stable nucleus is lead-206.
