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 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

The basic requirements for qualifying Class 1E equipment with interfaces that are to be used in nuclear power generating stations are described. The principles, procedures, and methods of qualification are covered. These qualification requirements, when met, will confirm the adequacy of the equipment design under normal, abnormal, design basis event, post design basis event, and in-service test conditions for the performance of safety functions. The methods are to be used for qualifying… read more equipment, extending qualification, and updating qualification if the equipment is modified. read less

This document presents standard test procedures for semiconductor X-ray energy spectrometers. Such systems consist of a semiconductor radiation detector assembly and signal processing electronics interfaced to a pulse height analyzer/computer. Test procedures for pulse-height analyzers and computers are not covered in this document. Section is essentially tutorial. This standard is not intended to imply that all tests described herein are mandatory, but only that such tests as are carried out shall be performed in accordance with the procedures described herein. Companion documents to this standard are ANSI/IEEE Std 300-1982 [1], ANSI/IEEE Std 301-1976 [2], and ANSI/IEEE Std 325-1971 [3]. The list of symbols and the glossary were derived from those in the companion documents. Contrary to previous convention in the X-ray spectroscopy field, this document utilizes the characteristic energy E of the X-ray rather than its wavelength λ. This approach is consistent with the fact that the basic quantity measured by this type of spectrometer is the X-ray energy. A convenient conversion is provided by the relationship λ(m) = 12.4 · 10-10 E-1(keV) λ(A0) = 12.4 E-1 (keV)

This Standard applies primarily to general-purpose laboratory cathode-ray oscilloscopes; it does not necessarily apply to specific kinds of oscilloscopes, such as those employing sampling techniques, nor to storage oscilloscopes, spectrum analyzers, television monitors, or other instruments using cathode-ray tube displays. Information for cathode-ray oscilloscopes designed or modified for specific applications and/or environments may require modification of certain listed information or the… read more addition of more information. read less

This document establishes standards for the technical performance of cabinet x-ray imaging systems used for screening at security checkpoints and other inspection venues. Included are all x-ray systems designed primarily for the inspection of baggage at airline, railroad, and bus terminals, and in similar facilities. An xray tube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionally incorporate portable shielding, is not considered to be a cabinet x-ray system.

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 for determination of gamma-ray efficiencies of germanium semiconductor detectors was developed in recognition of the increasing number of large-volume, low-activity samples being measured by gamma-ray spectroscopy. The standardized sample geometry and measurement techniques described, when used in conjunction with the relative efficiency measurement standard ANSI/IEEE Std 325-1971 (Reaff 1977), Test Procedures for Germanium Gamma-Ray Detectors, provide a meaningful assessment of… read more detector performance. It is recognized that many Marinelli beaker geometries are in use. However, the object of this standard is to specify a single configuration for the sole purpose of characterizing detector performance. read less
