Committed dose
scroll
The irradiation of tissue or organs with incorporated
radionuclides is distributed over the incorporation period. This period
depends on the physical half-life and the biokinetic behaviour of the
radionuclide. The committed dose is equal to the time integral of the
dose rate in a tissue or organ over the time. The integration period
for calculation of the committed dose amounts to 50 years for adults
and to 70 years for children.
The organ committed dose HT()
for an incorporation at the time t0 is the time integral
of the organ dose rate in the tissue or organ T:
where HT(t) is the average organ dose rate
in the tissue or organ T at the time t period
in years over which the integration is effected. If no value is indicated
for t, a period of 50 years for adults and the period from the respective
age to the age of 70 years for children are taken as a basis.
