Abstract

Abstract: Indoor radon ( 222 Rn), thoron ( 220 Rn) and their progeny concentrations were detected in several homes in Dimapur district, Nagaland, utilizing Direct Radon and Thoron progeny sensors based on solid-state Nuclear Track Detectors (Type-2 film) and pinhole type radon-thoron discriminating dosemeters. For three separate seasons, the annual inhalation dose has been determined in 80 residences in the research regions. The residences were chosen to have various types of housing, such as concrete, semi-wood/bamboo and bamboo, with varying levels of ventilation that contribute to indoor 222 Rn, 220 Rn and their progeny. The inhalation dose in the survey area lies between 0.33 and 3.04 mSvy −1 and is within the reference value as suggested by ICRP, 2018.
