License No. 21-03312-02 ATTN: David Barker, M.D.
12510 Harper Avenue St. Clair Shores, Michigan 48080 Gentlemen:
This refers to the routine safety inspection conducted by Ms. E. Matson and Mr. J. R. Mu11auer of this office on May 12, 1981, of activities authorized by NEC Byproduct Material License No. 21-03312-02 and to the discussion of our findings with Dr. Gomley and Dr. Mantel at the conclusion of the inspec-tion.
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-therapy equipment. Our measurement was made using a Victoreen Model 570 Condenser R-Meter with Model 621 chamber, calibrated by the hational Bureau of Standards Laboratory. The source-to-chamber distance was 80 l
centimeters and the field size used was ten by ten centimeters. After i
applying standard correction factors for temperature, pressure, attenua-tion, time error, roentgen-to-rad conversion, and decay for ten days, our measurement of the output of your teletherapy equipmen? was 126.9 rads per l
l minute. The most recent full calibration of your teletherapy equipment, conducted on May 2, 1981, reported a measured output for the same exposure parameters of 127 rads per minute.
