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 (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.
The purpose of this document is to provide standard, repeatable and verifiable methods to describe and measure the imaging performance characteristics of the systems listed above. It is not intended to determine the capability of a security screening system under specific operational inspection conditions.
New IEEE Standard – Active. 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 meter by 1 meter in cross-section.
