House-Type Analysis of 222Rn, 220Rn, and their Progeny in some Dwellings in Budgam Karewas of the Kashmir Valley

The average radiation dose received by humans each year as natural background is 2.4 mSv and long-term exposure to such harmful can be severely hazardous. According the BEIR-VI report, radon (222Rn) alone accounts for higher than 50% of all ambient from sources. Thus, its quantification essential evaluate any risk imposed human health. Newly created LR-115 films embedded in pinhole detectors have been used passive time-integrated assessment (222Rn), thoron (220Rn), their progeny levels permanent, semi-permanent, temporary house types. annual these three types were 31.7 Bqm-3, 37.2 55.2 respectively. value permanent semi-permanent houses was found lie below, while that exceeded worldwide 40 Bqm-3. Meanwhile, mean concentrations 31.3 40.9 temporary, 41.58 All outperformed global thoron.
