Alcance
This document specifies approaches for the determination of plutonium isotopes (238Pu, 239Pu and 240Pu) in urine using alpha spectrometry or inductively coupled plasma mass spectrometry (ICP-MS).It is applicable to the measurement of plutonium isotopes at levels which are appropriate for— workers handling plutonium in planned exposure situations, where detection limits are sufficiently low to be in accordance with dose limits, and— workers, members of the public and emergency responders in emergency exposure situations, where required detection limits can be much higher, and results need to be reported in a short timescale.This document does not provide information on when monitoring is carried out or the interpretation of the results in terms of dose or biological effects.
