American National Standard for Evaluation and Performance of Radiation Detection Portal Monitors for Use in Homeland Security 1. Overview 1.1 Scope This standard provide

26、s the testing and evaluation criteria for installed radiation detection portal monitors that detect radioactive materials (without identification capabilities). These systems are used to provide monitoring of people, packages, containers, and vehicles to detect illicit radioactive material transport

27、ation. Portal monitors are used for detection of photon- and neutron-emitting radioactive substances for the purposes of detection, interdiction, and prevention. 1.2 Purpose The purpose of this standard is to specify performance criteria and test methods used to evaluate installed radiation detectio
