Foreword

This standard describes the performance requirements for portal monitor instruments. The requirements stated are based on instruments used in support of efforts associated with the United States Department of Homeland Security.

Scope

This standard provides the testing and evaluating criteria for Radiation Detection Portal Monitors to detect radioactive materials that could be used for nuclear weapons or radiological dispersal devices (RDDs). Portal monitors may be used in permanent installations, in temporary installations for short-duration detection needs, or as a transportable system. These systems are used to provide monitoring of people, packages, and vehicles to detect illicit radioactive material transportation, or for emergency response to an event that releases radioactive material.
