Data for 220Rn in indoor and industrial environments are limited since it is widely accepted that its concentrations are meager on account of its diminutive half life, so its participation to respiration dose is disregarded on account of the incidence of considerable sources of ambient radiation. An effective dose from indoor 222Rn and its half springs accounts for almost half to the sources of natural radiation. However, indoor studies carried out in Asian continent imply the dose intake from 222Rn and its progeny may not be much lower than, or possibly more than, that from 220Rn. In light of this, an effort has been made to track Bangalore, India's 220Rn level distribution. Dosimeters were positioned throughout the room at fixed intervals from the wall, ceiling, and floor. To analyze the variances with respect to distance, all windows and doors were shut for 90 days. Additionally, dosimeters were placed in an upper and lower parabolic configuration. Cellulose Nitrate based Nuclear Track Detector (SSNTD) was used to examine the 220Rn coupled with 222Rn in test room. Higher concentrations were seen when the detector was moved away from the walls, ceiling, and floors of the room. This study covers the technical aspects of measuring the 220Rn distribution in a room. The findings are contrasted with figures provided in the literature for residences and regions with high background radiation levels.
