Change: Neutrons that have been slowed to the degree that they have the same average thermal energy as the atoms or molecules through which they are passing. The average energy of neutrons at ordinary temperatures is about 0.025 eV, corresponding to an average velocity of 2.2 з 103 m s-1. Ultraviolet View changes from previous version. (Word count: 1470)

Change: The process of emitting energy as waves or particles. The energy thus radiated. Frequently used for ionizing radiation except when it is necessary to avoid confusion with non-ionizing radiation. Radioactive Possessing the property of radioactivity Radioactive waste Useless material containing radionuclides. Frequently categorised in View changes from previous version. (Word count: 1291)

Change: A chemical change in the DNA in the nucleus of a cell. Mutations in sperm or egg cells or their precursors may lead to inherited effects in children. Mutations in body cells may lead to effects in the individual. Neutron An elementary particle with unit View changes from previous version. (Word count: 1157)

Change: Radiation that produces ionisation in matter. Examples are alpha particles, gamma rays, x-rays and neutrons. When these radiations pass through the tissues of the body, they have sufficient energy to damage DNA. Isotope Nuclides with the same number of protons but different numbers of neutrons. Not a synonym for nuclide. View changes from previous version. (Word count: 999)

Change: Electromagnetic radiation capable of producing the sensation of heat and found between light and radiofrequency radiations in the electromagnetic spectrum. Has subregions IRA, IRB and IRC Ion Electrically charged atom or grouping of atoms Ionization The process by which a neutral atom or View changes from previous version. (Word count: 907)

Change: Nuclear fission. A process in which a nucleus splits into two or more nuclei and energy is released. Frequently refers to the splitting of a nucleus of uranium-235 into two approximately equal parts by a thermal neutron with emission of other neutrons.Free radicalAgrouping of atoms View changes from previous version.

Change: The quantity obtained by multiplying the equivalent dose to various tissues and organs by a weighting factor appropriate to each and summing the products. Unit sievert, symbol Sv. Frequently abbreviated to dose. Electric field strength A measure of the intensity of an electric View changes from previous version. (Word count: 491)
