Section 335
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.
AGENCY NOTE: U.S. Nuclear
Regulatory Commission Regulatory Guide 8.39, Rev. 1, "Release of Patients
Administered Radioactive Material", published April 2020, exclusive of
subsequent amendments or editions, 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) 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 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 under Subpart F or H. The authorized user physician
shall state in writing that he or she is satisfied that patient compliance with
necessary instructions is likely and that the patient is suitable for release.
d) A
licensee shall retain a record for five 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.
