Radiological Safety Training for Uranium Facilities

Module 104 Internal Dose Control

Release of materials with the potential for uranium contamination shall

only be performed by personnel who are trained and authorized to do so.

The site radiological control organization is responsible for designating

and training these individuals.

i. Bioassay Monitoring

Bioassay monitoring, or measuring the amount of radioactivity inside

the body, can also be a way of determining if there has been a loss of

control of uranium contamination. For example, if a person who works

in an area with a relatively low airborne radioactivity concentration

and shows an intake consistent with a higher airborne radioactivity

concentration, there may have been a previously undetected loss of

airborne contamination control. Routine bioassay monitoring will

assist in making these determinations.
