Abstract

Abstract: In this investigation, Indoor Radon and Thoron Concentrations, the activity levels of Indoor Radon Progeny Levels, Thoron Progeny Levels and Annual Effective Inhalation Dose have been reported for different houses of Upper Assam mainly in oil field areas. BARC Twin cup dosimeters were deployed in the studied locations and LR-115(type II) solid state nuclear track detector was used to measure radon and thoron concentration level. The measurements have been carried out in fifteen dwellings of three different districts situated in and around the oil fields of upper Assam region. The indoor radon and thoron progeny levels as well as their concentrations with effective inhation doses are found maximum in RCC types of houses than Assam type of houses. The average indoor radon concentration varies from 168.5 Bq/m3 to 291.5 Bq/m3 for RCC houses where in AT type houses it varies from 81.7 Bq/m3 to 85.9 Bq/m3 whereas the thoron concentration varies from 12.58 Bq/m3 to 26.24 Bq/m3 in RCC type houses and it varies from 6.53 Bq/m3 to 7.60 Bq/m3 in AT type houses. The average effective inhalation dose in dwellings of different houses varies from 0.24 mSv/y to 0.32 mSv/y that lie within the safe limit recommended by ICRP, 2011 & ICRP, 1993) .
