Practice that causes exposure to natural radiation

The operator must investigate the radiation exposure caused by natural radiation if there is reason to suspect that the operations constitute radiation practices (Radiation Act article 45). In that case, ‘radiation practices’ refer to situations where human exposure to natural radiation is or may be hazardous to health.

Radiation practice that causes exposure to natural radiation may be

  • work in underground mines, mining sites and in other underground working areas, where the radon concentration of air is significantly high,
  • working in other working areas, where the radon concentration of air is significantly high,
  • delivering water for household consumption to consumers, when the water’s concentration of radioactive materials is higher than normal,
  • manufacturing building materials that contain a higher amount of natural radioactive materials than normal,
  • handling or storing materials that contain amounts of radionuclides that are higher than nor-mal,
  • practice that produces a significant amount of waste containing natural radioactive materials or that causes significant radionuclide releases in the environment,
  • flight operations where the flight personnel’s exposure to cosmic radiation is significant.
