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.
