General Information
IEC TR 61577-5:2019 provides basic data and technical information in order to support the design of instruments and their practical application for the measurement. The document covers 222Rn as well as 220Rn and the short-lived decay products of both. It is an accompanying document for the application of the technical standards series IEC 61577, and provides physical and technical fundamentals of the measurements methods.

IEC 61577-2:2014 describes the specific requirements for instruments measuring the activity concentration of airborne 222Rn and 220Rn outdoors, in dwellings and in workplaces including underground mines. This standard applies practically to all types of electronic measuring instruments that are based on either spot or continuous measurements. The different types of instrumentation used for measurements are stated in IEC 61577-1. This new edition includes the following significant technical changes with respect to the previous edition:
- addition of new requirements and tests concerning performance;
- harmonization of the requirements and tests concerning performance with other standards in this area.

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.
