摘要
Abstract
Passive method and positive measurement were used to measure 220Rn and its daughters equilibrium equivalent concentrations (EECTd), and equilibrium factors of 220 Rn for different distances from different sources were calculated based on the measurement. The equilibrium factors of 220Rn are 0. 003-0. 065 by passive measurement and 0.008-0.045 by positive measurement, respectively. The equilibrium factor of 220Rn appears a certain regular change in the spatial distribution.关键词
