View the full list If you’ve ever studied a periodic table of the elements (see below), you’re probably already aware that this table reveals a great deal about the chemical properties of the atoms that make up our world.But you may not realise that each square on the periodic table actually represents a family of isotopes — atoms which share the same name and chemical properties, but have different masses. They can split up or ‘decay’ and release radiation.Such isotopes are called radioactive isotopes or radioisotopes.You can think of protons and neutrons as the same kind of particle with one key difference: the protons are positively charged, while neutrons carry no charge.This means protons can “feel” electric or magnetic fields, while neutrons cannot.

NORM is the acronym for Naturally Occurring Radioactive Material, which potentially includes all radioactive elements found in the environment.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. 1979, 1986 © Harper Collins Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012 Cite This Source (ī'sə-tōp') One of two or more atoms that have the same atomic number (the same number of protons) but a different number of neutrons.Carbon 12, the most common form of carbon, has six protons and six neutrons, whereas carbon 14 has six protons and eight neutrons.However, the term is used more specifically for all naturally occurring radioactive materials where human activities have increased the potential for exposure compared with the unaltered situation.Concentrations of actual radionuclides may or may not have been increased; if they have, the term Technologically-Enhanced (TENORM) may be used.
