Abstract
The results of NPL’s twenty-sixth Environmental Radioactivity Proficiency Test Exercise are reported. Five different sample types were offered: an aqueous mixture of one alpha emitting radionuclide and two beta emitting radionuclides (designated ‘AB’), an aqueous mixture of three alpha-emitting radionuclides (‘A1’), an aqueous mixture of three beta-emitting radionuclides (‘B1’), an aqueous mixture of three gamma-emitting radionuclides (‘GH’), and a second aqueous mixture of five gamma-emitting radionuclides (‘GL’). In total, 392 results were submitted. A total of 377 were submitted for individual radionuclide analysis, of these results 299 (79 %) were in agreement with the proficiency test exercise assigned values, 46 (12 %) were questionable and 32 (8 %) were discrepant.
