This document describes a method for determination of the massic activity (Bq/kg) of iodine-131, caesium-134 and caesium-137 in animal feeding stuffs in monitoring laboratories. General guidance on the preparation of feed samples and the measurement of the three radionuclides iodine-131, caesium-134 and caesium-137 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. The method was fully statistically tested and evaluated in a collaborative trial comprising five animal feeding stuff samples for the radionuclides iodine-131, caesium-134 and caesium-137. Details on the successfully tested working range for each of the examined radionuclides are described in Annex C.
