Dr. John Worley License No. 14-15767-02 Administrator 117 Eleventh Street Ames, Iowa 50010 Gentlemen:
This refers to the routine safety inspection conducted by Dr. W. J. Adam and Mr. J. L. Lynch of this office on June 24, 1981, of activities at Mary Greely Memorial Hospital authorized by NRC Byproduct Material Licenses No. '4-15767-01 and Ne 14-15767-02 and to the discussion of our findings with Mr. Paul Anderson and Mr. S. Brian Smith 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 inspection consisted of a selective examination of procedures and rep-resentative 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 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 standarl correction factors for temperature, pressure, and time error, our measurement of the output of your teletherapy equipmer.t was 69.2 roentgens per minute in air. The most recent monthly spot check of your teletherapy equipment, conducted on June 15, 1981, reported a measured output for the same exposure parameters of 71.0 roentgens per minute. Applying a correction factor to account for nine days decay, the value calculated from the June 15, 1981 calibration becomes 70.8 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.
