On April 21, 2003, (68 FR 19321), the NRC published a direct final rule amending its regulations in 10 CFR part 35. This direct final rule clarified: the definitions of authorized users, authorized medical physicists, authorized nuclear pharmacists, and radiation safety officers; the notification requirements if the patient is in a medical emergency or dies; and the recordkeeping requirements for calibration of brachytherapy sources. In addition, the amendments corrected the title for the National Institute of Standards and Technology; clarified that prior to October 24, 2004, individuals who meet the training and experience requirements in Subpart J may undertake responsibilities specified in certain sections in Subparts B and D-H; and eliminated a restriction that training for ophthalmic use of strontium-90 can only be conducted in medical institutions. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on July 7, 2003. The NRC did not receive any comments that warranted withdrawal of the direct final rule. Therefore, this rule will become effective as scheduled.
