of dosages and performing checks for proper operation of survey meters;
(c) Calculating, measuring, and safely preparing patient or human research subject
dosages;
(d) Using administrative controls to prevent a medical event involving the use of
byproduct material;
(e) Using procedures to contain spilled radioactive material safely and using proper
decontamination procedures; and
(f) Administering dosages to patients or human research subjects that includes at least
three cases involving the oral administration greater than 1.22 gigabecquerels (33
millicuries) of sodium iodide I-131; and
(3) Has obtained written attestation that the individual has satisfactorily completed the
requirements in 105 CMR 120.558(C)(1) and (2), and is able to independently fulfill the
radiation safety-related duties as an authorized user for oral administration of greater than
1.22 gigabecquerels (33 millicuries) of sodium iodide I–131 for medical uses authorized
under 105 CMR 120.552. The attestation must be obtained from either:
(a) A preceptor authorized user who meets the requirements in 105 CMR 120.528,
120.556, 120.558, or equivalent Nuclear Regulatory Commission or Agreement State

equivalent Nuclear Regulatory Commission or Agreement State requirements, has
experience in administering dosages as specified in 105 CMR 120.556(B)(1)(b)6.b., and
concurs with the attestation provided by the residency program director. The residency
training program must be approved by the Residency Review Committee of the
Accreditation Council for Graduate Medical Education or the Royal College of
Physicians and Surgeons of Canada or the Council on Postdoctoral Training of the
American Osteopathic Association and must include training and experience specified
in 105 CMR 120.558(C)(1) and (2).
