Full Description
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.This method can be used for any type of environmental study or monitoring after appropriate sampling and handling, and test sample preparation.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]The method described in this document is applicable in the event of an emergency situation.
