摘　　要：^222Rn and ^220Rn enter the atmosphere mainly by crossing the air interface of either soil-air or building materials. The existence of relatively high concentration maintains a large ^222Rn, ^220Rn concentration gradient between the materials and open air. The present paper deals with the experimental measurement of ^222Rn, ^220Rn concentrations and the associated inhalation dose rates due to them in the dwellings of different characteristics. Higher concentrations and dose rates were observed in lower volume houses and the houses with granite flooring.

关 键 词：Indoor radon volume dose rate dwelling.
