ISO 13167:2015

ISO 13167:2015 specifies a test method for measuring actinides (238Pu, 239+240Pu, 241Am, 242Cm, 243+244Cm and 237Np) in water samples by alpha spectrometry following a chemical separation. The method can be used for any type of environmental study or monitoring. The volume of the test portion required depends on the assumed activity of the sample and the desired detection limit. The detection limit of the test method is 5 × 10-3 to 5 × 10-4 Bq/l for a volume of the test portion of 0,1 l to 5 l with a counting time of two to ten days.
