摘要
Abstract
Radon concentrations of a radioactive area before,during and after decommissioning were investigated using RAD 7 electronic radon measurement equipment.Adult annual effective dose resulted from radon was estimated.The average radon concentration before,during and after decommissioning were（35.5±3.8）-（38.7±4.1）Bq/m 3（,14.8±2.2）-（84.9±6.8）Bq/m 3 and（10.6±1.6）-（11.4±1.7） Bq/m 3, respectively.Radon concentration in the radioactive area was consistent with upper limit of background level before decommissioning;In the process of decommissioning,it increased first and decreased later with higher value than background level;It maintained constant with lower limit of background level after decommissioning.Adult annual effective dose resulted from radon irradiation before,during and after decommissioning were 0.97 mSv,1.34 mSv and 0.27 mSv respectively.关键词
