IEC 61577-1
Radiation protection instrumentation – Radon and radon decay product measuring instruments – Part 1: General principles
This standards addresses the instruments and associated methods for measuring isotopes 220 and 222 of radon and their subsequent short-lived decay products in gases. Helps to define type tests which have to be conducted in order to qualify these instruments.
Available in printed and PDF version.
IEC 61577-2
Radiation protection instrumentation – Radon and radon decay product measuring instruments – Part 2: Specific requirements for radon measuring instruments
Specifies the main performance characteristics of instruments intended for measurement of airborne radon volume activity, their specific method of testing and documentation requirements. Is to be used with IEC 61577-1.
Available in printed and PDF edition.
IEC 61577-3
Radiation protection instrumentation – Radon and radon decay product measuring instruments – Part 3: Specific requirements for radon decay product measuring instruments
Describes the specific requirements for testing instruments intended for measuring the activity concentration of airborne radon decay products and/or the volume potential alpha energy. Covers test procedures, radiation characteristics, electrical, mechanical, safety and environmental characteristics as well as identification certificates.
Available in printed and PDF edition.
IEC 61577-4
Radiation protection instrumentation – Radon and radon decay product measuring instruments – Part 4: Equipment for the production of reference atmospheres containing radon isotopes and their decay products (STAR)
IEC 61577-4 concerns the System for Test Atmospheres with Radon (STAR) needed for testing, in a reference atmosphere, the instruments measuring radon and RnDP. Provides guidance for those facing problems associated with the production of equipment for setting up reference atmospheres for radon and its decay products.
