Measurement of radioactivity. Gamma-ray emitting radionuclides. Generic test method using gamma-ray spectrometry1 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

BS EN 55016-2-4 on testing immunity to EMC is relevant to:

aircraft not-in-motion

Air handling units

Mechanical property limits are specified for all Class `A' alloys as defined in BS EN 573-4

The ERIC number obtained is dependent on the distribution of ink particle sizes
