Abstract: ABSTRACT newline newline newline newlineConceptually this thesis is structured in to five chapters namely Introduction, Literature survey, Instrumentation, Methods of Measurements, Results and Discussions followed by Conclusions, References and list of research publications by the author. The thesis eloquent the introduction to radioactivity, sources of background radiation, manmade sources, sources of 222Rn and 220Rn, the radioactivity in atmosphere, scope and objective of the present study. The extensive studies and surveys carried out for measuring the 222Rn/220Rn and their progeny levels , the source of 222Rn/220Rn(226Ra/232Th), radon in water and the back ground gamma radiation levels of the different environs of the world up to date are included. Definitions, specifications and block diagrams of the instruments which are used in the study are discussed extensively. Materials and methods, Calibration facility and standardization of dosimeter, Dosimetric methodology, Inhalation dose estimates are adopted by Solid Stare Nuclear Track Detectors (SSNTD) based double chamber dosimeter cup. newline newlineThe results and discussion, Variations of 222Rn, 220Rn and their progeny levels in different locations, different season, different floorings, different walls, different rooms and different volume of the dwellings of Bangalore Metropolitan, India and the distribution of 220Rn and its progeny levels in a dwelling. newline newline
