values is due to the relative health risk from exposure to uranium contamination

compared with these other nuclides.

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.

Bioassay Monitoring

Bioassay monito ring, or measuri ng the amount of ra dioactivity i nside the bod y,

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.
