Abstract:The total Background Radiation in the earth s environment is due to the contributions from natural (cosmic and terrestrial) as well as artificial (fall-out from nuclear weapon test, nuclear accidents, discharge from nuclear reactors etc.) Radiation sources. It comes mainly from uranium 238U series, thorium 232Th series and radioisotope of potassium, 40K.
