Summary

< p class=" MsoBodyText" > < span lang=" EN-GB" > This document 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.< / span>


< p class=" MsoBodyText" > < span lang=" EN-GB" > This method can be used for any type of environmental study or monitoring after appropriate sampling and handling, and test sample preparation.< / span>


< p class=" MsoBodyText" > < span lang=" EN-GB" > The detection limit of the test method is 5 × 10−3 Bq·l-1 to 5 × 10−4 Bq·l-1 for a volume of test portion between 0,1 l to 5 l with a counting time of two to ten days. This is lower than the WHO criteria for safe consumption of drinking water (1 Bq·l-1 or 10 Bq·l-1 depending on radionuclide).[4]< / span>


< p class=" MsoBodyText" > < span lang=" EN-GB" > The method described in this document is applicable in the event of an emergency situation.< / span>
