X-Ray Exposure Protection Although occupational radiation doses
at Virginia Tech are very low and current occupational limits
provide a very low risk of injury, the administration at
Virginia Tech recognizes that it is sensible to avoid
unnecessary exposure. It is therefore the policy of Virginia
Tech to reduce occupational exposures to a level that is as low
as reasonably achievable (ALARA). This will be accomplished
through sound radiation protection planning and practice, and a
commitment to policies that promote vigilance against unsafe
practice. Radiation workers shall not receive a dose in one
calendar quarter over the following limits: - Deep Dose
Equivalent 1,250 millirem (mrem) - Lens Dose Equivalent 3,750

Shallow Dose Equivalent (extremities) 12,500 mrem Individuals
under 18 years of age are not permitted to receive a dose
greater than 10% of the above limits. The maximum permissible
