IEEE N42.323AB-2026

This standard establishes calibration and calibration-related requirements for portable radiation protection instruments used for detection and measurement of levels of ionizing radiation fields or levels of radioactive surface contamination. For purposes of this standard, portable radiation protection instruments are those battery-powered instruments that are carried to a specific facility or location for use. Count rate meters and scalers, when used with an appropriate detection probe for quantifying activity, can be considered portable radiation protection instruments and are treated as a single unit for the purposes of this standard.



New IEEE Standard - Active. Testing, calibration, and calibration frequency requirements for portable radiation detectors used to directly measure α, β, photon, and neutron radiation are defined. Also defined are the calibration and testing requirements for α and β-gamma measurements of surface contamination levels using portable radiation detectors.
