Radon is produced by the radioactive decay of radium-226, which is found in uranium ores, phosphate rock, shales, igneous and metamorphic rocks such as granite, gneiss, and schist, and to a lesser degree, in common rocks such as limestone.
Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe. [1] Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2]
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Radioactive waste is a type of hazardous waste that contains radioactive material. It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. [1]
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
Releases of man-made radioactive materials which occur during an industrial or research accident. For instance the Chernobyl accident. Releases which occur as a result of military activity. For example, a nuclear weapons test, which have caused a global fallout, peaking in 1963 (the Bomb pulse), and up to 2.4 million deaths by 2020. [5]
Missouri state representatives are coming together to help protect residents from nuclear waste left over from the Manhattan Project. A new bipartisan special committee is focused on the lasting ...
