【Abstract】 The main points of quality control methods and technique of environmental radiological baseline study of Guangdong Daya Bay Nuclear Power Station are veported.Results of intercalibration of international and inland laboratories are given.The random chosen samples are checked and compared with two measurement methods.The data obtained in Daya Bay environment are put to the correlation statistics test using the liner regression analysis method between the correlative items such as 40K activity by gamma spectrum measurement and potassium content by chemical analysis,total α(β)activity and nuclide content,as well as environmental gamma radiation dose rate and TLD accumulation dose.The data of Daya Bay environmental radioactivity baseline level show good concordance and reliablity.更多还原
