WebJul 19, 2024 · Ultraviolet Radiation; Contributors and Attributions; High energy radiation, such as X-rays, \(\gamma\)-rays, and \(\beta\) particles (or electrons) are powerful mutagens. Since they can change the number of electrons on an atom, converting a compound to an ionized form, they are referred to as ionizing radiation. They can cause a … WebFeb 29, 2008 · 3 causes of mutation: 1. Radiation in form of gamma rays, x rays, etc 2. Viruses may cause mutation of cells of other organisms. 3.

WebMar 25, 2024 · The gamma ray is the most widely used ionizing radiation in mutagenesis. In fact, 63% of mutant varieties developed using a physical mutagen registered at the Mutant Variety Database (Joint FAO/IAEA) resulted from exposure to gamma rays. WebGramm ray are produced, classically, via the decay of unstable nuclei of atoms as they are experiencing a transition from the high energy to a lower energy state that known as …
WebThe US Environmental Protection Agency (EPA) sets limits for exposure to x-rays and gamma rays in part because it recognizes that this form of radiation can cause cancer. For more information on the classification systems used by these agencies, see Determining if Something Is a Carcinogen and Known and Probable Human Carcinogens. Written by WebWe know that X-rays increase mutation rates and also lead to chromosome rearrangements, but we do not known in detail which mechanisms of DNA repair lead to chromosomal rearrangements after this ...
