(a) A licensee shall authorize the release from its control any individual who has been administered unsealed byproduct material or implants containing byproduct material if:

(1) 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); or

(2) The calculated doses, based on methods and tables of activities described in NUREG-1556 (Vol. 9), "Consolidated Guidance about Materials Licenses: Program-Specific Guidance About Medical Use Licenses" show that 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).

(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).

(c) If the total effective dose equivalent to a nursing infant or child could exceed 1 millisievert (0.1 rem), assuming there are no interruption of breast-feeding, the instructions shall also include:

(f) Records of the released individuals containing unsealed byproduct material or implants containing byproduct material:

(1) A licensee shall retain a record of the basis for authorizing the release of an individual in accordance with He-P 4035.25, if the total effective dose equivalent is calculated by:
a. Using the retained activity rather than the activity administered;

b. Using an occupancy factor less than 0.25 at 1 meter;

d. Considering the shielding by tissue;

(2) A licensee shall retain a record that the instructions required by He-P 4035.25(b) and (c) were provided to a breast-feeding female 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); and

(3) The records required by He-P 4035.25(f)(1) and (f) (2) above shall be retained for 3 years after the date of release of the individual.
