The dose integrated over 50 years for adults (to age 70 for children) following an intake of radioactive material by inhalation, ingestion or through a wound. It is assigned in full to the year of the intake, even though most of it is delivered later, so a worker's record captures the whole consequence at once. It is estimated from bioassay results using biokinetic models for each radionuclide and chemical form.
Whole body count shows a cobalt intake, committed dose works out at 0.3 millisievert, assign it this quarter.
