Indoor radon measurement using LR-115 films (in bare mode) was carried out in four different seasons for a period of one year in 99 houses of four villages viz. Nongkasen & Markasa (N&M), Rambrai, Nongkhlaw and Nongstoin under West Khasi Hills District of Meghalaya, India. Seasonal variations are noted and discussed as well as the variations between different house types. The measured indoor radon concentration in N&M (119.56±5.55 Bq.m-3) and Nongstoin (102.74±5.10 Bq.m-3) villages are found to be higher than the lower limit set by the ICRP (100 Bq.m-3).
