Naeve Hospital Association License No. 22-15252-01 ATTN:
Dr. David J. Nelson License No. 22-15252-02 Radiation Safety Officer 404 Fountain Street Albert Lea, MN 56007 Gentlemen:
This refers to the routine safety inspection conducted by Dr. W. J. Adam of this office on October 28, 1981, of activities authorized by NRC Byproduct Material Licenses No. 22-15252-01 and No. 22-15252-02 and to the discussion of our findings with you 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 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, and timer error, our measurement of the output of your teletherapy equipment was 120 roentgens per minute in air.
The most recent full calibration of your teletherapy equipment, conducted on April 25, 1981, and extrapolated for October 25, 1981, reported a measured output for the same exposure parameters of 116 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 described in your letter dated October 17, 1977, regarding apparent items of noncompliance found during our September 16, 1977 inspection. We have no further questions regarding these matters.
