摘要
Because of the pronounced seasonal variation in the indoor levels of Rn concentration, it is necessary to make measurements over the entire period to arrive at an average of annual dose to the occupants. This paper gives the results of a study made on the seasonal variation of indoor Rn and its progeny concentration in a house in Bombay. It has been observed that the indoor Rn concentration follows a specific trend of seasonal variation. An average annual effective dose equivalent of 0.48 mSv has been estimated for the occupants of the house. © 1990.
