Dear Mr. Eisenhower:
A l
During a meeting on December 16, 1981, of the Interagency Policy Committee on Per-sonnel Dosimetry Performance Testing interest was expressed in the position of the NRC staff regarding the Cx values that should be included in ANSI N13.11. Specifi-4 cally, should the analytically dervived values be retained in the standard, or should they be replaced with values determined empirically at PNL.
The NRC staff position on this question is stated below:
1 (1) The differences between the empirical and analytical data are small in consideration of the intrinsic uncertainties associated with personnel j
dosimetry; either ser. of Cx values would be acceptable for the initial i
version of the standard,
'i (2) The final Cx values should be recommended by an authoritative organization such as the t!ational Council on Radiation Protection and Measurements, 3
the International Commission on Radiological Protection, or the.
International Commission on Radiation Units and Measurements (ICRU).
It appears that such recommendations will be made by the ICRU within the l
next year or two; if necessary, the standard can be modified at that time.
~
Thus, there would probably be little actual application of the Cx values published in the initial standard.
(3) The present controversy over the Cx values should not be allowed to
^
delay development and implementation of the personnel dosimetry processor accreditation program.
(4)
If ANSI has not issued the standard by the time NVLAP is ready to start 2
the accreditation program, the program should begin by utilizing the present version of the standard, i.e., the Health Physics Society Standards Committee standard.
Please include this statement in the meeting record.

Sincerely, UL-sdf j
Robert E. Alexander, Chief i-Occupational Radiation Protection Branch Office of Nuclear Regulatory Research
