Veterans Administration Hospital License No. 21-04234-01 ATTN: James H. Stevens License No. 21-04234-04 Director Southfield and Outer Drive Allen Park, MI 48101 Gentlemen:
This refers to the routine safety inspection conducted by Ms. E. Matson and Mr. J. Mu11auer of this office on May 13, 1981, of activities at Veterans Administration Hospital authorized by NRC Byproduct Material Licenses No. 21-04234-01 and No. 21-04234-04 and to the discussion of our findings with Mr. F. Smith and other 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 inspection consisted of a selective examination of procedures and representative records, observations, independent measurements, and interviews with personnel.
During this inspection, certain of your activities appeared to be in non-compliance with NRC requirements, as specified in enclosed Appendix A.
A written response, submitted under oath or affirmation, is required.
This inspection also included a measurement of the output of your tele-t therapy equipment. Our measurement was made using a Victoreen Model 570 Condenser R-Meter with Model 621 chamber, calibrated by the National l
Bureau of Standards Laboratory. The source-to-chamber distance was 80 centimeters and the field size used was 10 by 10 centimeters. After l
applying standard correction factors for temperature, pres,sure, attenua-tion, inverse square, time error, and roentgen-to-rad conversion, our l

Veterans Administration M 28 M Hospital measurement of the output of your teletherapy equipment was 127.32 rads per minute at the point of maximum buildup in a mini phantom. The most recent monthly decay chart for your teletherapy equipment, calculated for May 1, 1981, reported a measured output for the same exposure parameters of 131.8 rads per minute. Applying a correction faccor to account for 13 days decay, the valup calculated from your May 1, 1981 output verifi-cation becomes 131.18 F4s 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 1 5 percent.
We will gladly discuss any questioos you have concerning this inspection.
Sincerely, D. J. Sreniawski, Chief Materials Radiation Protection Section 2
