U *ti c-JA 2 Belleville, IL 62221 D ccj[gt 10 Gentlemen:
' /I w This refers to the routine safety in p c ion conducted by Mr. W. P. Reichhold of this office on December 9,1981, of activities authorized by NRC Byproduct Material Licenses No. 12-01567-01 and No. 12-01567-04 and to the telephone discussion of our findings with you on January 19, 1982.
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 teletherapy equipment. Our measurement was made using a Victoreen 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, and roentgen-to-rad conversion, our measurement of the output of your teletherapy equipment was 89.3 rads per minute. The most recent monthly spot check of your teletherapy equipment, conducted on December 4,1981, reported a measured output for the same exposure parameters of 91.7 rads per minute. Applying a correction factor to account for five days decay, the value calculated from the December 4, 1981, calibration becomes 91.5 rads 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 described in your letter dated September 24, 1979, regarding apparent items of nonconpli-ance found during our August 29, 1979, inspection. We have no fu er questions regarding these matters.
