Personnel dosimeters are assigned to individuals based upon their potential occupational exposure to penetrating radiation and regulatory requirements. Dosimeters are not effective for measurement of exposure from H-3, C-14, P-33 and S-35. Dosimeters are normally exchanged on a monthly basis. Temporary dosimeters are available for interim issue until permanent dosimeter assignment is established.
Dosimeters are required to monitor occupational exposure for the following:
- Adults likely to receive an annual dose from external sources >10% of the occupational exposure limits (500 mrem whole-body deep dose; 5,000 mrem extremity or shallow dose; 1,500 mrem lens of the eye).
- Individuals working with medical fluoroscopic equipment.
- Individuals entering a high radiation area.
- Declared pregnant women likely to receive a whole-body deep dose > 100 mrem from external sources during their pregnancy.
Contact information and areas of expertise can be found on the Contact Us page.
Documents
