Section XV-725 - Release of Individuals Containing Radiopharmaceuticals or Permanent Implants

A. A licensee may authorize the release from its control of any individual who has been administered unsealed byproduct material or implants containing byproduct material if the total effective dose equivalent to any other individual from exposure to the released individual is not likely to exceed 5 millisieverts (0.5 rem).

NOTE: The current revision of NUREG1556, Vol. 9, "Consolidated Guidance About Materials Licenses: Program-Specific Guidance About Medical Licenses," describes methods for calculating doses to other individuals and contains tables of activities not likely to cause doses exceeding 5 mSv (0.5 rem).

B. A licensee shall provide the released individual, or the individual's parent or guardian, with instructions, including written instructions, on actions recommended to maintain doses to other individuals as low as is reasonably achievable if the total effective dose equivalent to any other individual is likely to exceed 1 millisievert (0.1 rem). If the total effective dose equivalent to a breast-feeding infant or child could exceed 1 millisievert (0.1 rem) assuming there were no interruption of breast-feeding, the instructions shall also include:

1. guidance on the interruption or discontinuation of breast-feeding; and

2. information on the potential consequences, if any, of failure to follow the guidance.

C. The licensee shall maintain a record of the basis for authorizing the release of an individual in accordance with Subsections A and B of this Section for three years after the date of release of the individual, if the total effective dose equivalent is calculated by:

1. using the retained activity rather than the activity administered;

2. using an occupancy factor less than 0.25 at 1 meter;

3. using the biological or effective half-life; or

4. considering the shielding by tissue.

D. The licensee shall maintain a record for three years after the date of release of the individual that the instructions required by Subsection B of this Section were provided to a breast-feeding woman if the radiation dose to the infant or child from continued breast-feeding could result in a total effective dose equivalent exceeding 5 millisieverts (0.5 rem).
