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.

Decomposition is largely inhibited during advanced decay due to the loss of readily available cadaveric material. [15] Insect activity is also reduced during this stage. [ 16 ] When the carcass is located on soil, the area surrounding it will show evidence of vegetation death. [ 15 ]
Any decay daughters that are the result of an alpha decay will also result in helium atoms being created. Some radionuclides may have several different paths of decay. For example, 35.94(6) % [27] of bismuth-212 decays, through alpha-emission, to thallium-208 while 64.06(6) % [27] of bismuth-212 decays, through beta-emission, to polonium-212.
The song was inspired by a running gag on The Arsenio Hall Show, where Arsenio, while allegedly on a long drive, pondered certain thoughts and referred to them as "things that make you go hmmm...." The C+C song was a success in the US, reaching number four on the Billboard Hot 100 , number 31 on the Billboard Hot R&B Singles chart, and number ...

Ilya Stallone takes the quirky charm of medieval art and mashes it up with the chaos of modern life, creating comics that feel both hilarious and oddly timeless. Using a style straight out of ...
There is a half-life describing any exponential-decay process. For example: As noted above, in radioactive decay the half-life is the length of time after which there is a 50% chance that an atom will have undergone nuclear decay. It varies depending on the atom type and isotope, and is usually determined experimentally. See List of nuclides.
