Abstract—The average level of indoor radon concentration for uranium mining facilities. Environmental factors studies of
the residence in the uranium ore district is 282Bq/m3 and the indoor radon pollution are of great significance to take
maximum value can up to 570 Bq/m3 which exceed the national appropriate radiation protective measures.
