KEY FACTS

  • Terminology

    • Clinical Implications

      TERMINOLOGY

      • Definitions

        • Survey: Evaluation of radiological conditions and potential hazards
          • May be measurements (radiation levels measured with survey instruments or wipe tests), calculations, or combination of measurements and calculations
          • Surveys performed for radioactive contamination present on surfaces of floors, walls, laboratory furniture, production line, packages, and equipment
          • Measurements of radioactive material concentrations in air for areas where radioactive materials are handled or processed in unsealed form, and areas that could expose workers or public to inhalation of radioactive material
          • Measurements of radioactive material concentrations in water that is released to environment or sanitary sewer
            • Radioactive excreta is not regulated by NRC and any amount can be introduced to sewer system
          • Bioassays to determine kinds, quantities, or concentration, and in some cases, location of radioactive material in human body; bioassay can be made by direct measurement (in vivo counting) or by analysis and evaluation of material excreted or removed from human body (in vitro counting)
          • Surveys of external radiation exposure levels in both restricted and unrestricted areas
        • Surveys are performed on facilities, equipment, personnel, restricted and unrestricted areas, sealed source leak testing, testing before waste disposal, testing after spills or other radiation incidents, checking incoming/outgoing packages, and products produced
        • Surveys should be performed on restricted areas, where workers may be exposed to radiation levels that might result in radiation doses > 10% of occupational dose limits, and unrestricted areas if radiation doses might exceed public dose limits
