Abstract

The results of NPL's thirteenth Environmental Radioactivity Proficiency Test Exercise are reported. This exercise included preparing more than 200 samples and distributing them to 32 participants in the UK and 33 overseas participants. Eight different sample types were offered: an aqueous mixture of seven alpha emitters at two concentration levels, an aqueous mixture of six beta emitters at two concentration levels, an aqueous mixture of ten gamma emitters at two concentration levels, an aqueous mixture of four beta emitters and a solid neutron-activated concrete powder sample containing a variety of activation products. The level of performance was similar to that observed in the previous Exercise (2005); 73% of the results returned were in good agreement.
