NEN-EN-IEC 62363

scope:

This International Standard is applicable to portable and transportable contamination meters and monitors designed for the direct measurement or the direct detection of surface contamination by photon radiation emitting radionuclides and which comprise at least: - a detection assembly (comprising counter tube, scintillation detector or semiconductor detector, etc.), which may be connected either rigidly or by means of a flexible cable or incorporated into a single assembly; - a measurement assembly. The standard is applicable to: - photon surface contamination meters; - photon surface contamination monitors. The standard is applicable to detection assemblies that are designed to measure photon contamination from radionuclides which emit photons with energy in excess of 5 keV. In particular, this standard should be used to assess the performance of assemblies used to demonstrate that material is free from surface contamination by photon emitting radionuclides. This standard is also applicable to special purpose assemblies and to assemblies specifically designed to provide limited spectroscopic information to the user.
