IEEE PN42.35

New IEEE Standard - Active - Draft.
Minimum performance specifications and testing methods for the evaluation of radiation portal monitors, also known as RPMs, are contained in this standard. These monitors are large size installed or stationary RPMs. These instruments are primarily designed for the detection of radioactive materials emitting gamma rays and neutrons. The specifications for general, radiological, environmental, electromagnetic and mechanical performance are given and the corresponding testing methods are described. The documentation to be provided by the manufacturer is listed as part of the requirements. A number of informative annexes that provide useful information and guidance in implementing this standard are also contained in this standard.

This standard provides the testing and evaluation criteria for installed or stationary radiation portal monitors that passively detect radioactive materials (without identification capabilities). These systems are used to provide monitoring of people, packages, containers, and vehicles to detect illicit radioactive material transportation.
Radiation portal monitors are used for detection of photon- and neutron-emitting radioactive substances for the purposes of detection, interdiction, and prevention.
The purpose of this standard is to specify performance criteria and test methods used to evaluate installed or stationary radiation portal monitors for use in homeland security.
