Scope

GB/T 13163.2-2021 is the English-translated version of 辐射防护仪器氡及氡子体测量仪第2部分：222Rn和220Rn测量仪的特殊要求.

GB/T 13163.2-2021 is the Chinese standard "Radiation protection instrumentation - Radon and radon decay product measuring instruments - Part 2: Specific requirements for 222Rn and 220Rn measuring instruments".

Its scope clause reads: This document specifies special instruments for measuring airborne 222Rn and 220Rn activity concentrations in outdoor, residential and workplace (including underground mines).

Claim. This document applies to almost all types of electronic instruments based on single-point measurement or continuous measurement. 222Rn is made by pumping or diffusion And/or 220Rn air enters the sensitive volume of the detection unit or the activity concentration can be measured by air sampling (instantaneous sampling) at a specific time.

Various types of instruments for measurement are specified in IEC 61577-1. This document does not apply to instruments using activated carbon adsorption, electret or solid nuclear track detectors.
