摘要

从墙壁、地板和天花板散发出来的气体是封闭房间中氡(Rn)和钍(Tn)的主要来源。大部分陆地建筑材料的孔隙中含有气体,其浓度比大气中的气体浓度高1000 - 10000倍。这种高浓度导致建筑材料和周围空气之间存在相当大的氡/钍浓度差异。在本研究中,使用大量剂量计测量了班加罗尔大都市家庭室内氡、钍及其子代浓度。

STUDY OF THE CONNECTION BETWEEN ROOM SIZE AND RADON/THORON DOSE RATES IN BANGALORE METROPOLITAN AREA
The emanation of gases from the walls, floors, and ceilings is the main source of radon (Rn) and thoron (Tn) in enclosed rooms. The bulk of terrestrial construction materials contain gas in their pores in concentrations 1,000−10,000 times higher than those in the atmosphere. This high concentration results in a considerable radon/thoron concentration difference between the construction materials and ambient air. In this study, indoor radon, thoron, and their progeny concentrations, in Bangalore Metropolitan households, were measured using a significant number of dosimeters.
