American National Standard Minimum Performance Criteria for Active Interrogation Systems Used for Homeland Security

The performance criteria for active interrogation systems in homeland security applications are described in this standard. These systems are intended for non-intrusive inspection of closed containers, vehicles, and packages of a wide range of types and sizes. In these systems, the contents of an inspection zone are irradiated with penetrating ionizing radiation to determine the presence of a hidden substance-of-interest by the analysis of stimulated secondary radiations or nuclear-resonance absorption spectra that are indicative of the chemical and/or nuclidic composition of the substance-of-interest.
