UNE-EN IEC 61563:2021

This document applies to instruments used to measure the activity and/or activityconcentration of gamma-emitting radionuclides in food and/or foodstuffs. This documentapplies to instruments used both as gross count type instruments and pulse height analysingtype instruments used in field conditions and in measurement facilities. This document doesnot apply to high-resolution spectrometers that use germanium detectors.The instruments to which this document applies can be used to measure the activity andactivity concentration of gamma-emitting radionuclides for a wide variety of samples, such assoil, sewage, plant, and animal life.The object of this document is to establish performance requirements, to provide test methodsand to specify general characteristics, general test conditions, and radiological, environmental,mechanical and electromagnetic characteristics to be used to determine whether aninstrument meets the requirements of this document. The test results provide information toend-users and manufacturers regarding the capability of instrument for reliable measurementof the activity and/or activity concentration of gamma-emitting radionuclides.This document does not apply to sample preparation.
