ANALYSIS:

The proposed rulemaking amends Subchapter 11 rules regulating the used of radiation producing machines for therapeutic purposes in the healing arts. The term "medical event" is defined. Permittees are required to develop procedures to guard against medical events and similar incidents. Requirements for treatment planning simulators and other imaging equipment are updated to address newer technologies used in Oklahoma. The duration of certain record keeping requirements is increased to the life of the radiation machine permit. Changes have been proposed to the record keeping requirements in Subchapter 3 to complement those in Subchapter 11.

The Radiation Management Advisory Council voted to amend portions of the rules proposed by staff. These amendments allowed for electronic approval of treatment plans and clarified a separate document was not required to document the treatment plan. These amendments were in OAC 252:410-11-1(e)(9) and OAC 252:410-11-2(b).
