The monitoring results of gross a and gross beta activity from 2001 to 2005 for environmental airborne aerosol samples around the Qinshan NPP base are presented in this paper. A total of 170 aerosol samples were collected from monitoring sites of Caichenmen village, Qinlian village, Xiajiawan village and Yangliucun village around the Qinshan NPP base. The measured specific activity of gross alpha and gross beta are in the range of 0.02 similar to 0.38 mBq/m(3) and 0.10 similar to 1.81 mBq/m(3), respectively, with an average of 0.11 mBq/m(3) and 0.45 mBq/m(3), respectively. They are lower than the average of 0.15 mBq/m(3) and 0.52 mBq/m(3), of reference site at Hangzhou City. It is indicated that the specific activity of gross alpha and gross beta for environmental aerosol samples around the Qinshan NPP base had not been increased in normal operating conditions of the NPP.
