NUCLEAR REGULATORY COMMISSION



 

Change in Proficiency Testing Standard for Processors of Personal 

Dosimeters



AGENCY: Nuclear Regulatory Commission.



ACTION: Notice of change of proficiency testing standard.



-----------------------------------------------------------------------



SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) and the National 

Institute of Standards and Technology (NIST), U.S. Department of 

Commerce, began a joint effort in 1981, through an Interagency 

Agreement, to provide an accreditation program for processors of 

personnel dosimeters. That accreditation program, which is part of the 

Technology Administration of the U.S. Department of Commerce, is known 

as the National Voluntary Laboratory Accreditation Program (NVLAP) for 

Ionizing Radiation Dosimetry and is referred to as NIST/NVLAP. The 

purpose of this notice is to: (1) Acknowledge publication of a revised 

proficiency testing standard for personnel dosimetry performance by 

NIST/NVLAP; (2) inform the public and dosimetry processors of this 

action; and (3) identify significant changes in the standard.



EFFECTIVE DATE: April 11, 2002.



FOR FURTHER INFORMATION, CONTACT: Betty Ann Torres, Office of Nuclear 

Material Safety and Safeguards, U.S. Nuclear Regulatory Commission, 

Washington, DC 20555-0001, telephone 301-415-0191, e-mail: BAT@nrc.gov, 

or Carroll S. Brickenkamp, National Institute of Standards and 

Technology, Department of Commerce, NVLAP, Building 820, Room 286, 

Gaithersburg, MD 20899, telephone 301-975-4291, 

e-mail: cbrickenkamp@nist.gov.



SUPPLEMENTARY INFORMATION: NRC's regulations (10 CFR 20.1501) require 

that personnel dosimeters that need to be processed to determine dose 

must be processed and evaluated by a dosimetry processor that holds 

current personnel dosimetry accreditation from the NIST/NVLAP. 

Proficiency testing, currently required as part of the NIST/NVLAP 

accreditation process for Ionizing Radiation Dosimetry, is based on the 

standard issued by the American National Standard Institute (ANSI) and 

the Health Physics Society (HPS) for personnel dosimetry performance, 

ANSI/HPS N13.11-1993, as modified by NVLAP Bulletin Volume II, No. 1, 

``DOSIMETRY'' (January, 1995). The bulletin modifies dose equivalent 

conversion factors (Ck) found in Tables 2, 3, and C3 of 

ANSI/HPS N13.11-1993.

    A revision of ANSI/HPS N13.11-1993 was approved by the American 

National Standards Institute, Inc. in July 2001, and published as ANSI/

HPS N13.11-2001 in October 2001. A copy of the revised standard is 

available for a fee from the Health Physics Society at the following 

internet address: http://www.hps.org.

    The revision: (1) Adopts the conversion coefficients for photons 

issued by NVLAP Bulletin Volume II, No. 1, ``DOSIMETRY'' (January, 

1995); (2) reduces the number of test categories, based on radiation 

type and energy spectrum, from nine to six; (3) increases the number of 

possible radiation sources for test categories to which dosimeters can 

be exposed during testing; (4) lowers the permitted tolerance for all 

non-accident categories; (5) adds an angle test to the photon category; 

and (6) limits the number of individual dosimeters tested that is 

permitted to exceed the tolerance level for non-accident, non-neutron 

categories.

    NVLAP has determined that the revised standard, ANSI/HPS N13.11-

2001, will be implemented in the accreditation process as published. 

Contact Carroll Brickenkamp of NIST/NVLAP for information regarding the 

implementation of the revised standard, ANSI/HPS N13.11-2001.



    Dated at Rockville, Maryland, this 4th day of April, 2002.



    For the Nuclear Regulatory Commission.

Donald A. Cool,

Director, Division of Industrial and Medical Nuclear Safety, Office of 

Nuclear Material Safety and Safeguards.
