Abstract
In view of the fact that radon and its daughter product are major source of natural radiation exposure; the measurement of radon radiation in dwelling is assuming ever increasing importance. It is known from the recent surveys in many countries that radon and its progeny contributes significantly to total inhalation dose and its fairly established that radon when in held in large quantity causes lung disorder. The major sources of Radon are: soil that contains radon releasing material; water and natural gas that has passed through underground areas containing radon; solar heating system that use radon-emitting r o c k s to store heat granite rock; and uranium or phosphate mine tallings. Generally the radon concentration has been found to be not only varying with seasonal changes, but also with the mode of construction of houses, building material utilized and the ventilation conditions the houses with mud floors shows quite higher radon as compared to the houses with brick flooring. Even the radon survey in the soil gas and the dwellings has also been carried out using the Alpha Guard technique, which is based on pulse ionization chamber. The soil gas radon concentration shows a large variation from 1000Bq/m3 to 75000Bq/m3. The indoor radon concentration levels which have been measured in the dwelling by the alpha guard are quiet different as compared to that measured in these dwellings by the nuclear track etch technique(using the SSNTDs), indicating the importance of the SSNTDs in the long term integrated measurement of radon level in the dwellings. The occurrence of radon, its effect on the environment, measurement and protection particularly in Indian context are being discussed in this present paper.
