Results
In the following tables, the dose equivalent during the residency imterval and dose equivalent couu.n;.tments
to bone, bone.marrow
and the total body are presented.
The ulean for the dose equivalent
and dose equivalen~ commitment was determined from individual data
points which represent a wide distribution of residence intervals.
The mean value corresponds to the mean residence interval (years) for
the population described.
Residence intervals were determined
through verbal interro~ation of participants i.n the personnel
monitoring program.
