(e) Using procedures to contain spilled byproduct 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 of less than or equal to 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 120.557(C)(1) and (2), and is able to independently fulfill the
radiation safety-related duties as an authorized user for oral administration of less than or
