1. (1) Before the first medical use of a brachytherapy source on or after July 1, 2006, a licensee must have:

   1. (a) Determined the source output or activity using a dosimetry system that meets the requirements of OAR 333-116-0560(1);
   2. (b) Determined source positioning accuracy within applicators; and
   3. (c) Used published protocols currently accepted by nationally recognized bodies to meet the requirements of section (1) of this rule.
2. (2) Instead of a licensee making its own measurements as required in this rule, the 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 in accordance with section (1) of this rule.
3. (3) A licensee must mathematically correct the outputs or activities determined in section (1) of this rule for physical decay at intervals consistent with one percent physical decay.
4. (4) Only an authorized medical physicist must 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 section (1) of this rule.

5. (5) A licensee must retain a record of each calibration in accordance with OAR 333-100-0057. Each record must include:

   1. (a) The date of the calibration;
   2. (b) The manufacturer's name, model number, and serial number for the source and the instruments used to calibrate the source;
   3. (c) The source output or activity;
   4. (d) The source positioning accuracy within the applicators; and
   5. (e) The name of the individual, the source manufacturer, or the calibration laboratory that performed the calibration.

6. (6) Records of decay of strontium-90 sources for ophthalmic treatments must maintain a record of the activity of a strontium-90 source for the life of the source. The record must include:

   1. (a) The date and initial activity of the source; and
   2. (b) For each decay calculation, the date and the source activity.
