This refers to the routine safety inspection conducted by Ms. E. Matson of this office on October 20 and 21, 1981, of activities authorized by NRC Byproduct Material Licenses No. 21-02307-02 and No. 21-02307-03 and to the discussion of our findings with you and members of your staff at the conclusion of the inspection.
The inspection was an examination of activities conducted under your license as they relate to radiation safety and to compliance with the Commission's rules and regulations and with the conditions of your license. The inspec-tion cond sted of a selective examination of procedures and representative records, of servations, independent measurements, and interviews with personnel.
During this inspection, certain of your activities under License No.
21-02307-03 appeared to be in noncompliance with NRC requirements, as specified in enclosed Appendix A.
No items of noncompliance were identified for License No. 21-02307-02. A written response, submitted under oath or affirmation, is required.
This inspection also included a measurement of the output of your tele-therapy equipment. Our measurement was made using a Victoreen Model 570 Condenser R-Meter with Model 621 chsaber, calibrated by the National Bureau of Standards Laboratory. The source-to-chamber distance was 80 centimeters and the field size used was ten by ten centimeters. After applying standard correction factors for temperature, pressure, chamber factor, and time error, our measurement of the output of your teletherapy equipment was 60.6 roentgens per minute in air. The most recent full calibration of your teletherapy equipment, conducted on April 13, 1981, I1105 e
oco3 7 MR
{
~.
C Francis A. Bell Memorial Hospital 2-NOV 5 1981 reportad a measured output for the same exposure parameters of 64.1 roent-gens per minute in air. Applying a correction factor to account for six months and eight days decay, the value calculated from the April 13, 1981 calibration becomes 59.8 roentgens per minute.
Based on the close agreement in measured output values, we feel the actual output of your teletherapy equipment to be within established guidelines of 15 percent.
In addition to the above areas, the inspector examined actions for License No. 21-02307-02 described in your letter dated December 15, 1976, regarding apparent items of noncompliance found during our October 21, 1976 inspection.
We have no further questions regarding these matters.
We will gladly discuss any questions you have concerning this inspection.
Sincerely, D. J. Srrniawski, Chief Materia s Radiation Protection Section 2
