HPS ANSI/HPS N43.2 ✓ Most Recent [ Active ]

This standard provides guidelines specific to the radiation safety aspects of the design and operation of electrically powered/energized x-ray diffraction and fluorescence analysis equipment. This standard includes use of hand-held equipment using x-ray fluorescence to detect and identify contraband such as explosives and narcotics, in addition to other types of materials. It does not include electrical safety guidelines or other safety considerations outside the realm of radiation safety. Equipment employing x-rays from radioactive sealed sources is not within the scope of this standard.

Purpose

This standard concerns safe operation of analytical x-ray diffraction and fluorescence analysis equipment, establishes equipment design criteria, and sets up requirements for approved operating procedures. This standard also references reviews of the types of injuries resulting from accidental exposure to ionizing radiation, and recommends the establishment of health surveillance, and personnel monitoring programs. The circumstances under which operation of equipment must be limited to specially designated areas equipped with radiation barriers and warning signs are provided. Dose limits recommended by the National Council on Radiation Protection and Measurements are provided for reference. A list of references to selected articles on various aspects of radiation safety is given, and notes on the detection and measurement of radiation from x-ray diffraction and fluorescence analysis equipment are included in appendix A.
