ATTN: Mr. Ivan R. Finfrock, Jr.

Vice President Madison Avenue at Punch Bowl Road Morristown. New Jersey 07960 Gentlemen:

i Your letter dated June 27, 1975, in response to the letter dated May 27, 1975, which was sent to you by our Region I Office in

. King of Prussia, Pennsylvania, regarding calibration of radiation

' protection instruments, hac been referred to this office.

We note and confirm your commitment to do a two-point calibration j

of radiation protection instruments initially and at two-year

]

intervals. This type of calibration at' intervals of two years may be adequate for instruments used in routine surveys of low le gl radiation areas.similar to those found in a laboratory-type Prudence dictates, however, that careful cali-radfation program.

bration checks be made at more frequent intervals when instruments are subject to conditions, among others, of daily use in relatively high radiation levels under out of the' ordinary ranges of temper-4 ature and humidity; conditions often found in nuclear power plants.

In any event, it is expected that a forthcoming standard, ANSI N323, I

of'the American National Standards Institute will specify an annual frequency for this type of calibration. Tha standard will also I

cover the other basic requiremente of an adequate instrument main-tenance program.
