Universal Citation: 180 NE Admin Rules and Regs ch 7 ยง 060

Current through September 17, 2024

060.01 USE PARAMETERS. Before the first medical use of a brachytherapy source a licensee must:

(A) Determine the source output or activity using a dosimetry system that meets the requirements of 180 NAC 7-072.01;

(B) Determine source positioning accuracy within applicators; and

(C) Use published protocols currently accepted by nationally recognized bodies to meet the requirements of 180 NAC 7-060.01(A) and (B).

060.02 SOURCE MANUFACTURER OR CALIBRATION LABORATORY. A licensee may use measurements provided by the source manufacturer or by a calibration laboratory accredited by the American Association of Physicists in Medicine that are made according to 180 NAC 7-060.01.

060.03 PHYSICAL DECAY CORRECTION. A licensee must mathematically correct the outputs or activities determined in 180 NAC 7-060.01 for physical decay at intervals consistent with one percent physical decay.

060.04 PERFORM OR REVIEW OF CALCULATION MEASUREMENTS. An authorized medical physicist must perform or review the calculation measurements made according to 180 NAC 7-060.01, 7-060.02, or 7-060.03.

060.05 STRONTIUM-90 SOURCES FOR OPHTHALMIC TREATMENTS. Requirements for licensees using strontium-90 sources for ophthalmic treatments are as follows:

(A) Licensees who use strontium-90 for ophthalmic treatments must ensure certain activities specified in 180 NAC 7-060.05 (B) are performed by either:
(i) An authorized medical physicist; or

(ii) An individual who:
(1) Is identified as an ophthalmic physicist on a specific medical use license issued by the Department, NRC, or an Agreement State; permit issued by a Department, NRC, or Agreement State broad scope medical use licensee; medical use permit issued by an NRC master material licensee; or permit issued by a NRC master material licensee broad scope medical use permittee;

(2) Holds a master's or doctor's degree in physics, medical physics, other physical sciences, engineering, or applied mathematics from an accredited college or university;

(3) Has successfully completed one year of full-time training in medical physics and an additional year of full-time work experience under the supervision of a medical physicist;

(4) Has documented training in:
(a) The creation, modification, and completion of written directives; and

(b) Procedures for administrations requiring a written directive; and

(5) Is performing the calibration measurements of brachytherapy sources as detailed in 180 NAC 7-060;

(B) The individuals identified in 180 NAC 060.05 (A) must:
(i) Calculate the activity of each strontium-90 source that is used to determine the treatment times for ophthalmic treatments. The decay must be based on the activity determined under 180 NAC 7-060; and

(ii) Assist the licensee in developing, implementing, and maintaining written procedures to provide high confidence that the administration is according to the written directive. These procedures must include the frequencies that the individual meeting the requirements in 180 NAC 7-060.05 (A) will observe treatments, review the treatment methodology, calculate treatment time for the prescribed dose, and review records to verify that the administrations were according to the written directives; and

(C) Licensees must retain a record of the activity of each strontium-90 source according to 180 NAC 7-105.

060.06 RECORDS. A licensee must retain a record of each calibration according to 180 NAC 7-104.
