This standard applies to security screening systems that utilize x-ray or gamma radiation and are used to inspect people who are not inside vehicles, containers, or enclosures. Specifically, this standard applies to systems used to detect objects carried on or within the body of the individual being exposed. The following types of systems are included in the scope of this standard: ⎯ Systems designated as fixed, portal, re-locatable, transportable, mobile, or gantry. ⎯ Systems employing… read more detection of primary radiation (transmission systems), or scatter radiation (backscatter systems), or a combination of both. ⎯ Systems that are primarily imaging but that also may have complementary features such as material discrimination, or automatic active or passive threat alerts. This standard will not address how to test these complementary features. read less

This document establishes standard test methods and test objects for measuring the imaging performance of x-ray computed tomography (CT) security-screening systems. The quality of data for automated analysis is the primary concern. This document does not address the system's ability to use this image data to automatically detect explosives or other threat materials, nor is it intended for vendor-to-vendor comparisons of threat-detection performance. This standard does not purport to address… read more radiation safety and health practices associated with CT security-screening systems; users are advised to determine the applicability of regulatory limitations prior to use. Four annexes are included. Annex A is a bibliography (informative). Annex B (normative) provides mechanical drawings of the imaging test objects that compose the test article. A sample test report form is given in Annex C (informative). Finally, Annex D (informative) offers statistical guidance on multiple scans, summary statistics, and comparison of results. read less

This standard is intended to be used to determine the imaging performance of x-ray and gamma-ray systems utilized to inspect loaded or empty vehicles, including personal and commercial vehicles of any type; marine and air cargo containers of any size; railroad cars; and palletized or Unpalletized cargo larger than 1 m × 1 m in cross-section. The standard applies to systems that are the following: -- Single or multiple energy, source, or view -- Employ primary (i.e., transmission) and/or scatter… read more (e.g., backscatter) radiation detection -- Used to detect prohibited and controlled materials and/or to verify manifests -- Primarily imaging systems but also may have complementary features such as material discrimination and automatic active or passive threat alerts. This standard does not address how to test these complementary features. Adherence to all applicable mechanical and electrical safety requirements and compatibility with all applicable installation codes, including electro-magnetic compatibility requirements, is extremely important for any type of x-ray or gamma-ray screening system; however, identification of these requirements is not within the scope of this standard. read less

This standard establishes the minimum performance criteria for portable radiation protection instrumentation for use in ionizing radiation fields under both normal and extreme environmental conditions, i.e., all environmental conditions. For the portable radiation detection instrumentation addressed in this standard, the radiological ranges for the performance tests are as follows: the dose rate range of operation taken as background to 10 Gy/h (1000 rad/h); the activity-per-unit-area range for… read more surface contamination monitors taken as 0.01 Bq/cm (60 dpm/100 cm) or 0.05 Bq/cm (300 dpm/100 cm) to 200 Bq/cm (1.2 × 10 dpm/100 cm). The testing methods verify that the performance criteria are met over the range of operating conditions for each type of instrumentation. This standard does not specify which instruments or systems are required, nor does it consider the number of specific applications of such instruments. read less
