Description / Abstract:

This standard applies to the manufacture and operation of security screening systems that are intended to expose humans to primary beam x-rays, gamma radiation, or both. This standard does not address neutron-based systems. Examples of screening practices covered by this standard include the following:

Direct screening of humans to detect objects hidden within an individual's body or clothing.

Knowingly exposing human occupants to the primary beam when screening vehicles or structures.

Screening of orthopedic casts and prosthetic devices while being worn.

The standard provides requirements specific to the ionizing radiation safety aspects of both the design and operation of these systems. It does not include electrical safety guidelines or any other safety, performance, or use considerations outside the realm of radiation safety. The limits in this standard are not intended to apply to stowaways not authorized to be in the area and not known to be present prior to scanning.

It is recognized that the need for security might sometimes call for exceeding the dose limits set in this standard. This should be based on an analysis demonstrating that the security benefit outweighs the risk from the radiation exposure incurred by the individuals screened. This standard does not address the evaluation of the societal benefit of security screening. Therefore, screening operations that exceed this standard's dose limits are beyond the scope of this standard and shall not claim compliance with this standard.

Medical diagnostic systems should be used under medical supervision and are not covered by this standard.
