NF ISO 13167, M60-830 (07/2023)

This document describes a test method for measuring actinides (238Pu, 239+240Pu, 241Am, 242Cm, 243+244Cm, 237Np) in water samples by alpha spectrometry after chemical separation. This method can be used for any type of environmental study or monitoring after appropriate sampling, handling and preparation of test samples. The detection limit of the test method is between 5 × 10-3 Bq·l-1 and 5 × 10-4 Bq·l-1 for a test sample whose volume ranges from 0.1 l to 5 l and counting duration from two to ten days. This limit is lower than the WHO criteria for safe drinking water consumption (recommended level of 1 Bq·l-1 or 10 Bq·l-1 depending on the radionuclide).[4] The method described in this document is applicable in emergency situations.
