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 ...
A bottle of Radithor at the National Museum of Nuclear Science & History in New Mexico, United States. Radithor was a patent medicine that is a well-known example of radioactive quackery. It consisted of triple-distilled water containing at a minimum 1 microcurie (37 kBq) each of the radium-226 and 228 isotopes.
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.
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
As the longest-lived radioactive isotope ruthenium-106 has a half-life of only 373.59 days, it has been suggested that the ruthenium and palladium in PUREX raffinate should be used as a source of the metals after allowing the radioactive isotopes to decay. [4] [5] After ten half life cycles have passed over 99.96% of any radioisotope is stable ...
In a 1999 report by the International Atomic Energy Agency titled "Inventory of radioactive waste disposals at sea," a grainy map shows that at least 56,261 containers of radioactive waste were ...
Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium atoms. In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [1] and it is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H 2 O plus some HTO (3 HOH).
