Study of indoor radon and its progeny levels in rural areas of North India using LR-115 plastic track detectors

摘要

This paper presents the values of potential alpha energy concentration (PAEC) and concentration of radon measured in 51 houses of four Indian villages. The value of PAEC varies from 2.1+/-0.2 to 300.8+/-2.6 mWL with a geometric mean value of 29.7+/-0.8 mWL. The value of the concentration of radon varies from 19.4+/-1.9 to 2782.6+/-23.7 Bq/m(3) with a geometric mean value of 255.5+/-7.1 Bq/m(3). ne values of effective dose are found to vary from 0.34+/-0.03 to 48.11+/-0.41 mSv/yr with a geometric mean value of 4.8+/-0.12 mSv/yr. Most of the values have been found to be higher than the values in urban dwellings. (C) 2008 Elsevier Ltd. All rights reserved.
