Abstract

The results of NPL's twenty-first 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 powdered cement sample containing a mixture of alpha-emitting, beta-emitting and gamma-emitting radionuclides (`C1'). A total of 467 results were submitted; 450 of the results were analysed, and of these 76 % were in agreement with the Assigned Values.
