IEC 62438:2010适用于用于检测、量化和识别环境中的光子和/或中子发射体的移动辐射检测系统。这包括点辐射源和分布式辐射源。本标准的目的是: -确定仪器的最低要求； -确定部署和行动的要求； -提供测试和校准方法；和 -为适当设备的采购提供指导。本标准取消并取代1992年发布的IEC 61134。IEC 61134的范围仅限于钾、铀和钍地质矿床的勘探。IEC 62438:2010纳入了一系列当前可用的探测器技术，并纳入了中子监测。该标准还涉及广泛的移动平台应用，包括环境、应急响应、安全以及地质。

IEC 62438:2010 is applicable to mobile radiation detection systems used for the detection, quantification and identification of photon and/or neutron emitters in the environment. This includes point and distributed radiation sources. The object of this standard is to:
- establish minimum requirements for the instrumentation;
- establish requirements for deployment and operations;
- provide test and calibration methods; and
- provide guidance to procurement for appropriate equipment. This standard cancels and replaces IEC 61134, issued in 1992. The scope of IEC 61134 was restricted to exploration for geological deposits of potassium, uranium and thorium. IEC 62438:2010 incorporates the range of currently available detector technologies and incorporates neutron monitoring. This standard also relates to a wide range of mobile platform applications including environmental, emergency response, security in addition to geological.
