Section 335.8160 - Full Calibration Measurements on Remote Afterloader Units
Current through Register Vol. 48, No. 52, December 27, 2024
a) A licensee authorized to use a remote afterloader unit for medical use shall perform full calibration measurements on each unit:
b) To satisfy the requirement of subsection (a) of this Section, full calibration measurements shall include, as applicable, determination of:
c) A licensee shall use the dosimetry system described in subsection 335.8080(a) to measure the output.
d) A licensee shall make full calibration measurements required by subsection (a) of this Section in accordance with published protocols accepted by nationally recognized bodies.
e) In addition to the requirements for full calibrations for low dose-rate remote afterloader units in subsection (b) of this Section, a licensee shall perform an autoradiograph of the sources to verify inventory and sources arrangement at intervals not exceeding 1 quarter.
f) For low dose-rate remote afterloader units, a licensee may use measurements provided by the source manufacturer that are made in accordance with subsections (a) through (e) of this Section.
g) A licensee shall mathematically correct the outputs determined in subsection (b)(1) of this Section for physical decay at intervals consistent with 1 percent physical decay.
h) Full calibration measurements required by subsection (a) of this Section and physical decay corrections required by subsection (g) of this Section shall be performed by the authorized medical physicist.
i) A licensee shall maintain a record of the remote afterloader unit full calibrations required by this Section for 5 years.
j) The records shall include for each full calibration required by subsection (a) of this Section:
