Madera of this of fice.on March 31, 1982, of activities authorized by NRC Byproduct Material Licenses No. 24-00624-03 and No. 24-00624-02 and to the discussion of our findings with Mr. James Burris and Mr. Henry Sonday 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 consisted of a selective examination of procedures and representative records, observations, independent measurements, and interviews with personnel.
This inspection also included a measurement of the output of your tele-therapy equipment. Our measurement was made using a Victorcen Model 570 Condenser R-Meter with Model 621 chamber, 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, attenuation, inverse square, backscatter, timer error, chamber factor, roentgen-to-rad convers lon, our measurement of the output of your teletherapy equipment was 111.0 rads per minute at the point of maximun buildup in a muscle large phantom. The most recent monthly calibration of your teletherapy equipment, conducted on March'11, 1982, reported a measured output for the same exposure parameters of 116.6 rads per minute. Applying a correction factor to account for ten days decay, the value calculated from the March 11, 1982, calibration becomes 116.2 rads per minute.
