Rule 3701:1-58-48 | Calibration measurements of brachytherapy sources.
(A) Before the first medical use of a brachytherapy source, a licensee shall have:
(1) Determined the source output or activity using a dosimetry system that meets the requirements of paragraph (A) of rule 3701:1-58-60 of the Administrative Code;
(2) Determined source positioning accuracy within applicators; and
(3) Used published protocols currently accepted by nationally recognized bodies to meet the requirements of paragraphs (A)(1) and (A)(2) of this rule.

(C) A licensee shall mathematically correct the outputs or activities determined in paragraph (A) of this rule for radioactive decay at intervals consistent with one percent radioactive decay.
