Section 3701:1-58-62 - Full calibration measurements on remote afterloader units
Current through all regulations passed and filed through March 18, 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 paragraph (A) of this rule, full calibration measurements must include, as applicable, determination of:
(C) A licensee shall use the dosimetry system described in paragraph (A) of rule 3701:1-58-60 of the Administrative Code to measure the output.
(D) A licensee shall make full calibration measurements required by paragraph (A) of this rule 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 paragraph (B) of this rule, a licensee shall perform an autoradiograph of the source(s) to verify inventory and source(s) arrangement at intervals not exceeding one 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 paragraphs (A) to (E) of this rule.
(G) A licensee shall mathematically correct the outputs determined in paragraph (B)(1) of this rule for radioactive decay at intervals consistent with one per cent radioactive decay.
(H) Full calibration measurements required by paragraph (A) of this rule and radioactive decay corrections required by paragraph (G) of this rule must be performed by the authorized medical physicist.
(I) A licensee shall retain a record of each calibration in accordance with rule 3701:1-58-94 of the Administrative Code.
