Assumption models to calculate the radiation exposure through radioactive waste disposal in the waste water of a nuclear plant. The radiation generated during the decay of these radionuclides may in principle lead to a radiation exposure for human beings via the following paths:

  • External irradiation through spending time on sediment,
  • Internal irradiation through ingestion of radioactive substances withfood via
    • drinking water,
    • water – fish,
    • watering tank – cow – milk,
    • watering tank – animal – meat,
    • rainfall – forage plant – cow – milk,
    • rainfall – forage plant – animal – meat,
    • rainfall – plant,
    • mother’s milk

Models and calculation assumptions for radiation exposure via the waste water path are included in the administrative instruction “Determination of radiation exposure through radioactive waste disposal from nuclear plants or facilities”.
