HPS N43.3-2008 PDF Download

The HPS N43.3-2008 standard provides guidance for the design and use of installations using non-medical x-ray and sealed gamma-ray sources with energies up to 10 MeV. The standard aims to ensure that the exposure of individuals to radiation is kept as low as reasonably achievable (ALARA) and that the maximum permissible dose equivalent is not exceeded. This can be achieved through the implementation of engineered controls, management controls, safe operating procedures, appropriate equipment, and a comprehensive maintenance and surveillance program.

The standard also includes technical information on radiation shielding design, which can be useful in the design of radiation protection programs. However, it is important to note that this standard is primarily intended for technical experts involved in the design of installations and the establishment of radiation protection programs. For day-to-day operation of facilities, it is recommended to consult ANSI/HPS N43.11, which provides safe operating practices for non-medical x-ray radiographic and radioscopic equipment.

The standard differentiates between requirements and advisory recommendations. Requirements identified with the word "shall" are necessary to meet the standards of protection outlined in the document. Advisory recommendations identified with the word "should" are suggestions that should be implemented when practical.
