Naturally Occurring Uranium in Groundwater in Northeastern Washington State
Uranium is a radioactive element (radionuclide) that occurs naturally in rock, soil, and water – usually in low concentrations. Radionuclides are unstable atoms with excess energy and as radionuclides decay, they emit radiation. The uranium decay sequence also includes other radionuclides of concern such as radium and radon (DeSimone and others, 2014).
