New Dosimetry Technology
AGENCY: Nuclear Regulatory Commission.
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Nuclear Regulatory Commission (NRC) is amending its
regulations that govern radiological safety to allow licensees to use
any type of personnel dosimeter that requires processing to determine
the radiation dose, provided that the processor of the dosimeter is
accredited to process this type of dosimeter under the National
Voluntary Laboratory Accreditation Program (NVLAP), operated by the
National Institute of Standards and Technology (NIST).
DATES: The final rule is effective January 8, 2001 unless significant
adverse comments are received by November 24, 2000. If the effective
date is delayed, timely notice will be published in the Federal
Register.

SUPPLEMENTARY INFORMATION:
Background
NRC regulations at 10 CFR Part 20, Subpart F--Surveys and
Monitoring, Sec. 20.1501 (c) ``General'' specify that whole body
personnel dosimeters that require processing to determine the radiation
dose must be processed and evaluated by a processor holding current
personnel dosimetry accreditation under the NVLAP. In addition, the
dosimetry processor must be approved in this accreditation process for
the types of radiation that most closely approximate the types of
radiation for which the individual wearing the dosimeter is monitored.
Although there is no specification in Sec. 20.1501, ``General'' on
the type of NVLAP accredited dosimeters that are acceptable, other
parts of the NRC regulations, namely Part 34, ``Licenses for Industrial
Radiography and Radiation Safety Requirements for Industrial
Radiographic Operations;'' Part 36, ``Licenses and Radiation Safety
Requirements for Irradiators;'' and Part 39, `` Licenses and Radiation
Safety Requirements for Well Logging'' specify the use of either a film
badge or a thermoluminescent dosimeter (TLD). At the time that these
rules were adopted, film badges and TLDs were the only available
dosimeters that required processing to determine the radiation dose.
Discussion
Modern developments in personnel dosimetry have produced dosimeters
that have higher sensitivities to radiation than either film badges or
TLDs, and require processing to determine the radiation dose. For
example, the Optically Stimulated Luminescent Dosimeter involves the
use of optical lasers for processing, unlike the processing for a film
badge that requires photographic development or the TLD that is
processed using heat. New dosimeter technologies and other processing
techniques are likely to appear in the near future. Therefore, the
specific references to film badges or TLDs in 10 CFR 34.47, ``Personnel
Monitoring;'' Sec. 36.55, ``Personnel Monitoring;'' and Sec. 39.65,
``Personnel Monitoring'' should be removed to allow the use of
dosimeters that require alternative processing techniques. This rule is
intended to remove the specific requirements and to allow the use of
any dosimeter that requires processing to determine the radiation dose,
provided that the processor of the dosimeter holds appropriate NVLAP
accreditation.
Discussion of Amendments by Section
Section 34.47 Personnel Monitoring
This section is amended to delete the limitation to the use of film
badges and TLDs and to allow the use of any personnel dosimeter that
requires processing to determine the radiation dose, provided that the
processor of the dosimeter holds appropriate NVLAP accreditation. The
replacement of dosimeters specified in this section is also revised to
conform to the language used in paragraph (a) of this section.
Section 34.83 Records of Personnel Monitoring Procedures
In paragraphs (c) and (d), the existing requirement to retain
exposure records of lost or damaged film badges or TLDs until license
termination is modified to use conforming terminology of ``personnel
dosimeter'' in place of ``film badges or TLDs'.
Section 36.55 Personnel Monitoring
This section is amended to allow irradiator operators to wear any
personnel dosimeter requiring processing to determine radiation dose,
provided that the dosimeter is processed and evaluated by an accredited
NVLAP processor. Processing intervals specified in this paragraph are
also revised to incorporate conforming language.
Section 36.81 Records and Retention Periods
This section is modified to use conforming terminology of
``personnel dosimeter'' in place of ``film badges and TLDs''.
Section 39.65 Personnel Monitoring
This section is revised to remove the limitation to the use of film
badges and TLDs, and to permit the use of a personnel dosimeter that is
processed by an accredited NVLAP processor. The frequency of processing
dosimeters specified in this paragraph and the record retention
requirement are revised to incorporate conforming language.
Procedural Background
Because NRC considers this action to be noncontroversial and
routine, the NRC is using the direct final rule procedure for this
rule. This action will become effective January 8, 2001. However, if
the NRC receives significant adverse comments on the associated
proposed rule published concurrently in the proposed rules section of
this Federal Register, by November 24, 2000, then the NRC will publish
a document that withdraws this action and will address the comments
received in response to the proposed amendments. These comments will be
addressed in a subsequent final rule. Absent significant modifications
to the proposed changes requiring republication, the NRC will not
initiate a second comment period on this action.
[[Page 63751]]
Agreement State Compatibility
Under the ``Policy Statement on Adequacy and Compatibility of
Agreement State Programs'' approved by the Commission on June 30, 1997,
and published in the Federal Register on September 3, 1997, (62 FR
46517), this direct final rule will be a matter of compatibility
between the NRC and the Agreement States, thereby providing consistency
among Agreement State and NRC requirements. A Compatibility Category
``C'' designation means an NRC program element, the essential
objectives of which Agreement States should adopt to avoid conflicts,
duplication, or gaps in the regulation of agreement material on a
nationwide basis and that, if not adopted, would result in an
undesirable consequence. The manner in which the essential objectives
are addressed need not be the same as NRC provided the essential
objectives are met. A Compatibility Category ``D'' designation means an
NRC program element which does not need to be adopted by Agreement
States for purposes of compatibility.
The revisions to Sec. 34.47 and Sec. 34.83 are classified as
Category C, and the revisions to Sec. 36.55 and Sec. 36.81 are
classified as Category D. The revisions to Sec. 39.65 are classifed as
Category C for paragraph (a) and Category D for paragraph (c). Although
these sections are subject to varying degrees of compatibility with
regard to the Agreement States, this direct final rule is not expected
to affect the compatibility of the Agreement State regulations.
Plain Language
The Presidential Memorandum dated June 1, 1998, entitled, ``Plain
Language in Government Writing'' directed that the Government's writing
be in plain language. The NRC requests comments on this direct final
rule specifically with respect to the clarity and effectiveness of the
language used. Comments should be sent to the address listed under the
heading ADDRESSES above.
Voluntary Consensus Standards
The National Technology Transfer Act of 1995, (Pub. L. 104-113),
requires that Federal agencies use technical standards that are
developed or adopted by voluntary consensus standards bodies unless the
use of such a standard is inconsistent with applicable law or otherwise
impractical. In this direct final rule, the NRC would revise 10 CFR
34.47, 10 CFR 36.55, and 10 CFR 39.65 to allow the use of any dosimeter
that requires processing to determine the radiation dose, provided that
the processor of the dosimeter holds appropriate NVLAP accreditation.
This action does not constitute the establishment of a standard that
establishes generally-applicable requirements.
Environmental Impact: Categorical Exclusion
The Commission has determined that this direct final rule is the
type of action described in categorical exclusion 10 CFR 51.22(c)(2).
Therefore, neither an environmental impact statement nor an
environmental assessment has been prepared for this direct final rule.
Paperwork Reduction Act Statement
This direct final rule does not contain a new or amended
information collection requirement subject to the Paperwork Reduction
Act of 1995 (44 U.S.C. 3501 et seq.). Existing requirements were
approved by the Office of Management and Budget, Approval Number 3150-
0007 for 10 CFR Part 34, Approval Number 3150-0158 for 10 CFR Part 36,
and Approval Number 3150-0130 for 10 CFR Part 39.
Public Protection Notification
If a means used to impose an information collection does not
display a currently valid OMB control number, the NRC may not conduct
or sponsor, and a person is not required to respond to, the information
collection.
Regulatory Analysis
A regulatory analysis has not been prepared for this direct final
rule because this rule is considered a minor, nonsubstantive amendment
that has no economic impact on NRC licensees or the public.
Small Business Regulatory Enforcement Fairness Act
In accordance with the Small Business Regulatory Enforcement
Fairness Act of 1966, the NRC has determined that this action is not a
major rule and has verified this determination with the Office of
Information and Regulatory Affairs, Office of Management and Budget.
Regulatory Flexibility Certification
In accordance with the Regulatory Flexibility Act of 1980, 5 U.S.C.
605(b), the NRC certifies that this rule will not, if promulgated, have
a significant economic impact on a substantial number of small
entities. This direct final rule simply amends present regulations to
allow use of any dosimeter that requires processing to determine the
radiation dose, provided that the processor of the dosimeter holds
appropriate NVLAP accreditation. The use of this new technology is
optional and will have no significant impact on small entities because
use of the new technology is optional and no changes are being made to
affect the use of the technology currently available.
Backfit Analysis
The NRC has determined that the backfit rules (10 CFR 50.109,
72.62, or 76.76) do not apply to this direct final rule because these
amendments do not involve any provisions that would impose backfits as
defined. Therefore a backfit analysis is not required.
