Dosimeters are not typically used to
monitor for radiological doses
resulting from tritium. The weak
energy beta radiation will not
penetrate the dosimeter.

The best method used to determine

if an individual has an uptake of
HTO or soluble organically bound
tritium is by bioassay (urinalysis).
Routine urine samples, collected at
some predetermined frequency and
counted for the tritium content,
provide a very sensitive
measurement of tritium in the body.
This is especially true if the time of
uptake is known.
Air sampling results may be used to
assess dose from other types of
special tritium compounds.
Routine Versus Non-Routine
1. Prospective: Prospective
bioassay is routine bioassay.
Routine: Routine urinalysis
is conducted on a preset
b. Non-routine or Special:
Non-routine bioassay is done
whenever a potential exposure
to tritium is suspected.
