IEC 61577-3 Ed. 2.0 b:2011

IEC 61577-3:2011 describes the specific requirements for instruments measuring the volumetric activity of airborne short-lived radon decay products and/or their ambient potential alpha-energy concentration outdoors, in dwellings, and in workplaces including underground mines. This standard applies practically to all types of electronic instruments that are based on grab sampling, continuous sampling technique and electronic integrating measurement methods. This new edition includes the following significant technical changes with respect to the previous edition:
- implementation of new requirements and tests concerning radiation detection performance;
- implementation of new requirements and tests concerning environmental performance;
- harmonization of the requirements and tests concerning electrical and mechanical performance with other standards in the area of radiation protection instrumentation.
