Abstract

Background: RADON, THORON and their progenies are the most important contributions to human exposure from natural sources. RADON exists in soil gas, BUILDING MATERIALS, Indoor atmosphere etc. Among all the natural sources of radiation dose to human beings, inhalation of RADON contributes a lot. The work presented here emphasizes the long term measurements of RADON, THORON and their progeny concentrations in about 100 dwellings using solid state nuclear track detectors. Materials and Methods: Measurements were made using DOSIMETERs and the concentrations were estimated by knowing the track density of films through spark counter, and sensitivity factor for bare, filter and membrane films. Results: Presence of RADON and THORON in houses is the effect of several aspects such as the activity concentrations of uranium, radium and thorium in the local soil, BUILDING MATERIALS, ventilation of houses and also entry of RADON into houses through the cracks in floor/wall. Conclusion: The observations reveal that the concentrations of RADON and/or THORON are relatively higher in granite than in concrete, cement and bricks. In continuation to this the concentration observed in bathrooms is more compared to kitchen, bedroom and living rooms. This study discloses that the residential rooms of good ventilation will avoid the health hazards due to RADON and its rich materials.
