【 摘 要 】

Radon is the daughter product of 226Ra, and is exist in large concentration compared to all other radioactive elements present in the atmosphere and contributes more annual effective dose to human than all other radiation sources. Inhaling radioactive radon mainly causes of lung cancer. The effect of radon exposure prevention measures is initially determined by how successfully and quickly information persuades people to test properties. Usually, this is accomplished through educating locals on the dangers radon poses to their health.The activities of radon, thoron and their progenies were measured in the present study using pinhole dosimeters with alpha sensitive films, LR-115 type-II in 26 dwellings with a variety of flooring materials, including cement, tiles, mud, and granite, in both excellent and bad ventilation conditions along the Kabini river bank. The total yearly effective dose obtained from the study area is varied from 0.81 to 5.26 mSv.y-1, with an average dose value of 2.54 mSv.y-1 and is less than the suggested range ofICRP 2011 and the WHO -2011recommended level.
