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.

A paper has been written on the radioactivity in oysters found in the Irish Sea, these were found by gamma spectroscopy to contain 141 Ce, 144 Ce, 103 Ru, 106 Ru, 137 Cs, 95 Zr and 95 Nb. [citation needed] In addition, a zinc activation product (65 Zn) was found, this is thought to be due to the corrosion of magnox fuel cladding in cooling ...
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).
The actinide series is a group of chemical elements with atomic numbers ranging from 89 to 102, [note 1] including notable elements such as uranium and plutonium.The nuclides (or isotopes) thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and (in the case of neptunium ...
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] Radium may also be released into the environment by human activity: for example, in improperly discarded products painted with radioluminescent paint.
Radioactive elements, except tritium and carbon-14, have been mostly filtered from the water that is being released into the Pacific Ocean. Radioactive elements, except tritium and carbon-14, have ...
Uranium is a naturally occurring element found at low levels within all rock, soil, and water. This is the highest-numbered element to be found naturally in significant quantities on Earth. According to the United Nations Scientific Committee on the Effects of Atomic Radiation the normal concentration of uranium in soil is 300 μg/kg to 11.7 mg/kg.
A massive sinkhole has been leaking at least 215 million gallons of radioactive water into an aquifer in this state. ... Stash of Roman-era coins buried 2,000 years ago found in field.
