UNCERTAINTY EVALUATION FOR MULTIDETECTOR PASSIVE DOSEMETERS USING A TWO-STAGE MEASUREMENT MODEL AND THE MONTE CARLO METHOD.

abstract：:Data on the daily urinary excretion of thorium (Th) was obtained from 15 non-exposed adult German subjects. A radiochemical neutron activation analysis method was developed and standardised especially for this purpose. The daily urinary excretion of 232Th was found to be in the range 1.9-14.9 microBq d(-1) with a mean...
