ASTM C 1112

ASTM C 1112, Standard Guide for Application of Radiation Monitors to the Control and Physical Security of Special Nuclear Material, is a standard published by ASTM International.

The standard was first published in June 1999 and was updated in 2005. The standard provides a guide to selecting, calibrating, testing, and operating radiation monitors to detect special nuclear material (SNM), including searching pedestrians, packages, and motor vehicles for concealed SNM. This may be one part of a security plan for nuclear materials. SNM radiation monitors are commercially available in three different forms: Small Hand-Held Monitors, Automatic Pedestrian Monitors, and Automatic Vehicle Monitors.
