摘要
Abstract
To solve the difficulties in “original”radon concentration measuring,this paper proposed an overflow type electret radon concentration measurement method and device.A 4 L jar was applied as ionization chamber and E-perm electret was applied as radon detector.When the steady radon contaminated water flowed through the ioniza-tion chamber,water radon was released with the nitrogen aerating disturbance.The average radon concentration was detected by the E-perm electret.Furthermore,RAD7-H2O kit was used to measure the radon concentration for comparison.The results showed that different methods had well consistency with the water radon concentration in the range of 4 to 97 Bq/L.关键词
