辐射防护仪器.检测放射性物质非法贩运的车载移动系统

[中文适用范围]： 本文件适用于用于检测放射性材料非法贩运的车辆载移动系统（也称为移动系统或移动监测器）；这些仪器也可用于重大公共活动的保护和大面积快速筛查。这些车辆载移动系统包括安装在一个车辆（例如汽车或货车）中的一个或多个辐射探测器，该车辆主要在公共道路上行驶。本文件不适用于安装在其他类型车辆（例如飞机、直升机、火车或船只）上的检测系统。本文件涵盖的车辆载检测系统设计用于检测车辆运动时的放射性源。它们也可用作扫描静止或移动物体的静止监测器。车辆载移动系统检测伽马辐射，并可包括中子检测和/或伽马发射放射性核素的识别。本文件的目的是为用于检测放射性材料的车辆载移动系统设定最低要求。本文件确立了通用、辐射、气候、机械、电气和电磁以及文件要求，以及相关的测试方法。 [外文原描述]： IEC 63121:2020 applies to vehicle-mounted mobile systems (also known as mobile systems or mobile monitors) that are used for the detection of illicit trafficking of radioactive materials; these instruments may also be used for protection of major public events and for rapid screening of large areas. These vehicle-mounted mobile systems consist of one or more radiation detectors mounted in a vehicle, e.g., car or van, which travels predominantly on public roads. This document does not apply to detection systems mounted in other types of vehicles, e.g., planes, helicopters, trains, or boats. Vehicle-mounted detection systems covered by this document are designed to detect radioactive sources while the vehicle is in motion. They may also be used as stationary monitors that scan stationary or moving objects. Vehicle-mounted mobile systems detect gamma radiation and may include neutron detection and/or identification of gamma-ray emitting radionuclides.
