Section 335.2110  Release of Individuals Containing Unsealed Radioactive Material or Implants Containing Radioactive Material

a)         A licensee may authorize the release from its control of any individual who has been administered unsealed radioactive material or implants containing radioactive material if the total effective dose equivalent to any other individual from exposure to the released individual is not likely to exceed 5 mSv (0.5 rem) following assessment of the patient's medical, living and working conditions.

b)       If the total effective dose equivalent to any other individual is likely to exceed 1 mSv (0.1 rem), the licensee shall provide the released individual and, as determined appropriate by the authorized physician user, the individual's spouse, parent, guardian or other primary caregiver, with verbal and written instructions, on actions recommended to maintain doses to other individuals as low as is reasonably achievable.  If the total effective dose equivalent to a minor, pregnant individual, or nursing infant or child could exceed 1 mSv (0.1 rem), assuming there were no interruptions of breast-feeding, the instructions shall also include:

1)         Guidance on the interruption or discontinuation of breast-feeding;

2)         Guidance on minimizing close and/or extended contact; and

3)         Information on the potential consequences, if any, of failure to follow the guidance.

c)         Release of the patient pursuant to this Section shall be approved by an authorized physician user who is approved for the applicable use of radioactive material (i.e., Subpart F or Subpart H of this Part).  The authorized user physician shall state in writing that he or she is professionally satisfied that patient compliance with necessary instructions is likely and the patient is suitable for release.

d)         A licensee shall retain a record for 5 years after the release of the individual for the following:

1)         The basis for authorizing the release of an individual in accordance with subsections (a) and (b) of this Section to include the assessment and evaluation criteria for the patient's medical, living and working conditions, activities of radioactive material used (i.e., retained or administered activity), occupancy factors, biological or effective half-life of radioactive material, shielding by tissue, and means of estimating doses to any other individual and the physicians.

2)         The instructions for each patient required by subsection (b) of this Section.

3)         The physician's certification for patient release required by subsection (c) of this Section.
