This document replaces GB/T 34138-2017 "Environmental, electromagnetic and mechanical performance requirements for radiation protection instruments" and GB/T 34138-Compared with 2017, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

a) The definitions of some terms have been changed (see 3.1.8, 3.1.9, 3.1.7 and 3.1.8 of the 2017 edition);

b) The details of the selected test methods have been changed (see 7.2.2, 7.3.2, 7.4.2, 7.5.2, 7.6.2, 2017 edition 7.2.2, 7.3.2, 7.5.2, 7.4.2, 7.6.2);

c) Added guidance and recommendations for equipment and instrumentation settings (see 7.2.3, 7.3.3, 7.5.3, 7.6.3, 7.7, 8.4.4, 8.5.3, 9.2.3, 8.5.3, 9.6.1.3, 9.6.2.3).

This document is modified to adopt IEC 62706:2019 "Environmental, electromagnetic and mechanical performance requirements and test methods for radiation protection equipment".

The technical differences between this document and IEC 62706:2019 and their reasons are as follows.

Introduction

Radiation protection instrumentation, including instruments for the detection and identification of radioactive materials and radionuclides, is used in many different environments.

During normal use, radiation protection equipment is typically exposed to varying temperatures, humidity, electromagnetic fields and mechanical stresses (e.g. shock and vibration).

Radiation instruments may be wearable, handheld, vehicle mounted, moved from one location to another, or fixedly installed.

All conditions related to various uses. In order to ensure consistency between standards, for environmental, electromagnetic and mechanical performance requirements are established.

Radiation Protection Instrumentation Environmental, Electromagnetic and Mechanical Performance requirements and test methods

1 Scope

This document specifies the environmental, mechanical and electromagnetic performance requirements and test methods for radiation protection equipment. This document also provides some test Guidance is provided for the setup of test equipment and the instrument under test (IUT).

This document applies to body-worn (e.g. personal radiation detectors, backpacks and dosimeters), hand-held, transportable, mobile Tabletop and fixed instruments.

NOTE. The purpose of this document is to specify the possible use environment of radiation protection equipment for the design and testing of the equipment.
