BS EN 17462:2021 Animal feeding stuffs. Methods of sampling and analysis. Determination of the radionuclides Iodine-131, Caesium-134 and Caesium-137 in feed
Edition: 2021
Description of BS EN 17462:2021 2021
This document describes a method for determination of the massic
activity (Bq/kg) of 131I, 134Cs and 137Cs in animal feeding stuffs
in monitoring laboratories. General guidance on the preparation of
feed samples and the measurement of the three radionuclides 131I,
134Cs and 137Cs by high resolution gamma-ray spectrometry is
provided. The current document aims to be complementary to existing
standards. More information on sample preparation, moisture content
determination and gamma-ray spectrometry can be found in specific
standards referred to in this document. For example, generic advice
on the equipment selection, detectors and quality assurance for
gamma-ray spectrometry can be found in ISO 20042 [1]. The method
was fully statistically tested and evaluated in a collaborative
trial comprising five animal feeding stuff samples for the
radionuclides 131I, 134Cs and 137Cs. Details on the successfully
tested working range for each of the examined radionuclides are
described in Annex C.
