摘要
Abstract
The filtration efficiency of 7Be aerosol was measured hy the method of threelayer membrane. The filtration efficiency of 7Be aerosol is 85.7％ with amendment on decay effect. The annual change regularity of 7Be aerosol activity concentration around Hangzhou area was analyzed, and it is concluded that the main reason is the seasonal rainfall.关键词
