HPS N13.12-2013 PDF Download

The HPS N13.12-2013 standard provides guidelines for the clearance of items and materials from areas that are controlled to protect individuals from radiation exposure. The standard establishes a primary radiation dose criterion and screening levels for surface and volume radioactivity for groups of radionuclides. It is important to note that this standard does not cover naturally occurring radioactive materials (NORM) in bulk, radioactive materials on or in persons, release of licensed or regulated sites or facilities, radioactive materials on or in foodstuffs, release of land or soil intended for agricultural purposes, clearance issues related to national defense or security, process gases and liquids discharged in accordance with federal or state license requirements, radioactive material in transport, or radioactive materials governed by regulations or exemptions. It is also emphasized that this standard is not a substitute for radiological criteria for decommissioning or intervention criteria during cleanup projects. Instead, it provides protective screening levels for the clearance of items or materials.
