摘要:Data for 220Rn in indoors and workplace environment is scare due to the general perception that its levels are negligible due to its shorter half life, and subsequently its contribution to the total inhalation dose is ignored, in the presence of other significant sources of natural radiation. The Bhabha Atomic Research Center (BARC), Mumbai, India has completed a countrywide monitoring program of 220Rn along with 222Rn in the dwellings using 222Rn/220Rn discriminating Solid State Nuclear Track Detector (SSNTD) based dosimeter systems with large participation of research groups from different parts of the country. Details about measurement, standardization of dosimeters and evaluation of the inhalation dose is presented in this paper. Results are compared with the values reported in literature for dwellings as well as in high background radiation areas
