A Look at Radiological Water Contaminants

Radiological water contaminants are undesirable radioactive substances that have entered a water supply. They are also known as radionuclides. Typical, naturally-occurring radiologicals found in drinking water include, "isotopes of radium, uranium and radon, among others. Fission products from man-made nuclear reactions are also of concern today, particularly radioactive cesium and iodine." 1. Get price
