Abstract

The results of NPL's fourteenth Environmental Radioactivity Proficiency Test Exercise are reported. This exercise included preparing 245 samples and distributing them to 37 participants in the UK and 41 overseas participants. Seven different sample types were offered: an aqueous mixture of nine alpha emitters at two concentration levels, an aqueous mixture of four beta emitters, an aqueous mixture of three beta emitters, an aqueous mixture of eight gamma emitters at two concentration levels and a solid neutron-activated concrete powder sample containing a variety of activation products. The level of performance was lower to that observed in the previous Exercise (2007); 67% of the results returned were in good agreement.
