216 Special Control Levels

Certain situations may require lower individual exposure control levels. In addition to considering recommendations

from senior radiological control and medical officials, the contractor senior site executive should obtain advice from

professionals in other disciplines such as human resources and legal in establishing special control levels. The contractor

senior site executive may wish to establish these special control levels using a radiological health advisory group.

A special control level for annual occupational exposure should be established for each radiological worker with a

lifetime occupational dose exceeding N rem, where N is the age of the individual in years. The special control level

should allow the individual's lifetime occupational dose to approach and, if practicable, fall below N rem during

ensuing years as additional occupational dose is received.

An employer should be attentive to special circumstances of employees, such as those undergoing radiation

therapy, and establish special control levels as appropriate.

Special controls on an individual dose should not be implemented in a manner that interferes with that individual's

right to work. If reasonable efforts to implement the special control level below 1 rem per year threaten to restrict

the individual's right to work or are otherwise unsuccessful, the contractor senior site executive should authorize

any doses in excess of the special control level, but not to exceed the regulatory dose limits.
