Abstract

The results of NPL's twentieth Environmental Radioactivity Proficiency Test Exercise are reported. Six different sample types were offered: an aqueous mixture of two alpha emitters and two beta emitters (designated 'AB'), an aqueous mixture of four alpha emitters ('A1'), an aqueous mixture of three beta emitters ('B1'), an aqueous mixture of four gamma emitters ('GH'), a second aqueous mixture of four gamma emitters ('GL') and a vitreous sample containing three gamma emitters ('GS'). A total of 506 results were submitted; 82 % of the results were in agreement with the Assigned Values.
