A. Personnel Monitoring

External Dose

Insert site specific requirements

Dosimeters are not typically used to

monitor for radiological doses

resulting from tritium. The weak

energy beta radiation will not

penetrate the dosimeter.

(insert any site specific monitoring

procedures)

Internal Dose

Show OT 45

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.

1. Prospective: Prospective

Routine Versus Non-Routine Bioassay

bioassay is routine bioassay.

Monitoring

Routine: Routine urinalysis is

conducted on a preset periodic

basis.

Non-routine or Special: Non-

routine bioassay is done

whenever a potential exposure to

tritium is suspected.

Workplace Monitoring

Air monitoring and surface contamination surveys

are used to verify that loose contamination is not

present. They provide an early indication of potential

problems.
