Measurement of radioactivity. Gamma-ray emitting radionuclides. Generic test method using gamma-ray spectrometry Ingestion-build-93833 In BS EN 13230-1 mechanical1 Scope This document describes the methods for determining the activity in becquerel (Bq) of gammaray emitting radionuclides in test samples by gamma ray spectrometry. The measurements are carried out in a testing laboratory following proper sample preparation. The test samples can be solid, liquid or gaseous. Applications include: routine surveillance of radioactivity released from nuclear installations or from sites discharging enhanced levels of
