MEASUREMENT OF INDOOR RADON ACTIVITY LEVELS IN JOWAI REGION, MEGHALAYA, INDIA
In the present work, the activity levels of radon in dwellings and schools are reported for Jowai region. We have used LR-115 type 2 films which belong to the class of Solid State Nuclear Track Detectors (SSNTDs); the ‘Bare-mode’ methodology was adopted. Higher concentration levels were observed in concrete structures as compared to Assam type structures. Higher geometrical mean value was recorded for the first floor of multi-storeyed school buildings as compared to the ground floor.
