DANSK DS/EN 60325 PDF

This international standard is applicable to radiation meters and monitors designed for the direct measurement or the direct detection of surface communication by alpha and/or beta radiation emitting nuclides 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. Some meters and monitors consist of detection assemblies and measurement assemblies where it is possible to separate the detector assembly and use alternative detection assemblies. Conformity with the standard can either by achieved by: All combinations of the detection assembly and the measurement assembly conforming to the requirement of this standard or the detection assembly and the measurement assembly separately conforming to the relevant part of this standard in isolation. The standard is applicabe to: - alpha surface contamination meters; - alpha surface contamination monitors; - beta surface contamination meters; - beta surface contamination monitors; - alpha/beta surface contamination meters; - alpha/beta surface contamination monitors.
