Abstract

The results of NPL's nineteenth Environmental Radioactivity Proficiency Test Exercise are reported. Eight different sample types were offered: an aqueous mixture of five alpha emitters (designated 'AL'), a second aqueous mixture of five alpha emitters ('AH'), an aqueous mixture of three beta emitters ('B1'), a second aqueous beta mixture containing four beta emitters ('B2'), an aqueous mixture of four gamma emitters ('GL'), a second aqueous mixture of four gamma emitters ('GH'), a peat sample containing four radionuclides ('P') and a sandy soil sample containing four radionuclides ('S'). A total of 721 results were submitted; 78% of the results were in agreement with the Assigned Values.
