PART 1 Administrative Control Levels and Dose Limits

To accomplish DOE's objective of maintaining individual doses well below regulatory limits, challenging numerical

administrative control levels should be established below the regulatory limits to administratively control and help reduce

individual and collective radiation dose. These control levels should be multi-tiered with increasing levels of authority

required to approve higher administrative control levels.

Unless otherwise indicated, administrative, lifetime, and special control levels and dose limits are stated in terms of the

total effective dose equivalent, which is the sum of the doses received from internal and external sources.

211 Administrative Control Level

Approval by the appropriate Secretarial Officer or designee should be required prior to allowing an individual to

exceed 2,000 millirem in a year.

Facility management should establish an annual facility administrative control level based upon an evaluation of

historical and projected radiation exposures, work load, and mission. The specific value selected should be more

restrictive than the administrative control level established by the Program Office. This control level should be

reevaluated annually. The choice of a low level for one year does not preclude choosing either a higher or lower

level in a subsequent year. The facility administrative control level should be approved by the contractor senior site

executive

For most facilities, an annual facility administrative control level of 500 millirem or less will be challenging and

achievable. An annual administrative control level above 1,500 millirem is in most cases not sufficiently

challenging to meet the goals of this Standard.

No individual should be allowed to exceed the facility administrative control level without the prior written

approval of the radiological control organization and cognizant facility management. Authorization by the

contractor senior site executive is recommended.

When there is wide variation in the expected doses to the various work groups at a single facility, facility

management should develop work group-specific administrative control levels to control worker doses below the

regulatory limits.

212 Lifetime Control Level

Efforts should be made to control each individual's lifetime occupational dose below a lifetime control level of N

rem where N is the age of the individual in years. Article 216 discusses special control levels for radiological

workers who have doses exceeding N rem.

To ensure compliance with the lifetime control level, efforts should be made to determine the lifetime occupational

dose of individuals expected to receive more than 1 rem in a year. The lifetime occupational dose is determined by

summing all occupational internal and external doses received during the individual's lifetime.

The internal contribution to lifetime occupational dose from intakes prior to January 1, 1989, may be calculated in

terms of either cumulative annual effective dose equivalent or committed effective dose equivalent. The committed

effective dose equivalent should be used to the extent that adequate data are available to calculate doses in these

terms.
