| |
| GENERAL SAFETY STANDARDS FOR INSTALLATIONS USING NONMEDICAL SEALED GAMMA-RAY SOURCES
| |
|
| |
|
| ==A. INTRODUCTION== | | ==A. INTRODUCTION== |
| This guide directs the reader to the type of information acceptable to the U.S. Nuclear Regulatory Commission (NRC) to approve the initial transfer of devices containing byproduct material to persons generally licensed under Title 10, Section 31.5, "Certain Detecting, Measuring, Gauging, or Controlling Devices, and Certain Devices for Producing Light or an Ionized Atmosphere," of the Code of Federal Regulations (10 CFR 31.5) (Ref. 1) or equivalent regulations of an Agreement State.
| | Section 20.101, "Exposure of Indcividuals to Radia tion in Restricted Areas," of 10 CFR Part 20, "Stand ards for Protection Against Radiation," provides that, subject to certain enumerated exceputios, no licensee shall xces, use, or transfer licensed material in such a manner as to cause any indiidual in a restncted area to receive a dose in excess of the limits specified therein. |
|
| |
|
| The requirements for transferring gamma-ray sources to general licensees appear in 10 CFR 32.51, "Byproduct Material Contained in Devices for Use Under § 31.5; Requirements for License to Manufacturer, or Initially Transfer" (Ref. 2). One method of complying with the requirements of 10 CFR 32.51 appears in NUREG-1556, Volume 3, "Consolidated Guidance about Materials Licenses: Applications for Sealed Source and Device Evaluation and Registration" (Ref. 3).
| | Paragraph (c) of §20.1 provides that licensees, in addition to complying with the requirements set forth m Part 20, should make every reasonable effort to maintain radiation exposures as far below the limits specified in Part 20 as practicable. |
| This regulatory guide endorses the description of the information to be submitted in the application for the initial transfer and installation of sealed gamma-ray sources contained in the current revision of Volume 3 of NUREG-1556 as a method acceptable to the NRC staff.
| |
|
| |
|
| Volume 3 of NUREG-1556 provides the applicants and reviewers with information concerning how to file a request, a listing of the applicable regulations and industry standards, policies affecting evaluation and registration, administrative procedures to be followed, information on how to perform the evaluation and write a registration certificate, and the responsibilities of the registration certificate holder. The NRC issues regulatory guides to describe and make available to the public methods that the NRC staff considers acceptable for use in implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in reviewing applications for permits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions that differ from those set forth in regulatory guides will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission.
| | This guide describes general safety practices which are acceptable to the Regulatory staff a methods for nonmedical users of sealed garnrna-ray sources to corn ply, in part, with the above Commrnission regulations. |
|
| |
|
| This guide was issued after consideration of comments received from the public.
| | Basic to this general safety standard are the use of appropriate equipment, ample shielding, and safe oper ating procedures. |
| | |
| Regulatory guides are issued in 10 broad divisions C1, Power Reactors; 2, Research and Test Reactors; 3, Fuels and Materials Facilities; 4, Environmental and Siting; 5, Materials and Plant Protection; 6, Products; 7, Transportation; 8, Occupational Hea lth; 9, Antitrust and Financial Review; and 10, General.
| |
| | |
| Electronic copies of this guide and other recently issued guides are available through the NRC's public Web site under the Regulatory Guides document collection of the NRC's Electronic Reading Room at http://www.nrc.gov/reading-rm/doc-collections/ and through the NRC's Agencywide Documents Access and Management System (ADAMS) at http://www.nrc.gov/reading-rm/adams.html, under Accession No. ML081140498.
| |
| | |
| Rev. 1 of RG 6.5, Page 2 Radiation safety programs for sealed gamma-ray sources or devices are structured on two key points. First, the byproduct material will not breach its containment and contaminate the environment or unnecessarily expose individuals to radiation. Second, the sealed source or device will be installed and operated correctly and in accordance with the manufacturer's instructions. Regulatory Guide 6.4, "Verification of Containment Properties of Sealed Radioactive Sources," discusses verification of the byproduct containment system. This guide directs the reader to the type of information necessary for the NRC to review the safety standards for the installation of the source or device.
| |
| | |
| This regulatory guide contains information collection requirements covered by 10 CFR Parts 31, and 32 that the Office of Management and Budget (OMB) approved under OMB control numbers 3150-0016, 3150-0001, respectively. The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number.

| ==B. DISCUSSION== | | ==B. DISCUSSION== |
| As part of its redesign of the materials license program, the NRC consolidated and updated numerous guidance documents for material licenses into the multivolume NUREG-1556. Various volumes in the NUREG-1556 series provide current, program-specific guidance on testing, licensing, decommissioning, and terminating materials licenses.
| | American National Standards Institute Subcommittee N43-5 has revised National Bureau of Standards Hand book 93, "Safety Standard for Non-Medical X-Ray and Sealed Gamma-Ray Sources," and the revised standard, designated ANSI N543-1974 1 and now entitled "Gen eral Safety Standard for Installations Using Non-Medical X-Ray and Sealed Gamma-Ray Sources," was approved by the American National Standards Institute in 1974. The standard provides recommendations for appropriate |

|
| |
|
| Volume 3 of NUREG-1556 provides guidance to applicants for requests for sealed source or device safety evaluations and registrations. It also provides reviewers of such requests with the information and materials necessary to determine that the products are acceptable for licensing purposes. It provides the applicants and reviewers with information concerning how to file a request, a list of the applicable regulations, industry and consensus standards, policies affecting evaluation and registration, administrative procedures to be followed, information on how to perform the evaluation and write a registration certificate, and the responsibilities of the registration certificate holder.
| | Con tamied in appendixes to the standard are guiddTce and extensive data for use in deter-rruruuon of se d barrier thicknees for inrstallatcon.s usiig XVra,, e-uip mernt or sealed sources of cobaJt-6,0. |
|
| |
|
| Many of the volumes of NUREG-1556 also contain appendices that include (1) copies of necessary forms, (2) sample applications and completed examples for different types of applications, and (3) examples of the types of supporting information, such as implementing procedures that the applicant may need to prepare. The NRC is placing added emphasis on conducting its regulatory activities in a risk-informed and performance-based manner. This approach is intended to be less prescriptive and to allow licensees the flexibility to implement the agency's regulations in a manner that is more specific to their needs yet still meets the regulatory requirements. By supplying examples, the NRC seeks to provide information to meet the needs of applicants for licensure without being prescriptive. Guidance in NUREG-1556 represents one means of complying with NRC regulations and is not intended to be the only means of satisfying the regulatory requirements.

Section 20.101, "Exposure of Indcividuals to Radia tion in Restricted Areas," of 10 CFR Part 20, "Stand ards for Protection Against Radiation," provides that, subject to certain enumerated exceputios, no licensee shall xces, use, or transfer licensed material in such a manner as to cause any indiidual in a restncted area to receive a dose in excess of the limits specified therein.
Paragraph (c) of §20.1 provides that licensees, in addition to complying with the requirements set forth m Part 20, should make every reasonable effort to maintain radiation exposures as far below the limits specified in Part 20 as practicable.
This guide describes general safety practices which are acceptable to the Regulatory staff a methods for nonmedical users of sealed garnrna-ray sources to corn ply, in part, with the above Commrnission regulations.
Basic to this general safety standard are the use of appropriate equipment, ample shielding, and safe oper ating procedures.
B. DISCUSSION
American National Standards Institute Subcommittee N43-5 has revised National Bureau of Standards Hand book 93, "Safety Standard for Non-Medical X-Ray and Sealed Gamma-Ray Sources," and the revised standard, designated ANSI N543-1974 1 and now entitled "Gen eral Safety Standard for Installations Using Non-Medical X-Ray and Sealed Gamma-Ray Sources," was approved by the American National Standards Institute in 1974. The standard provides recommendations for appropriate

POSITION The requirements and recommended practices con tamed in ANSI N543 1 are acceptable for the construc tion and use of installations unng sealed pmma-ra> sources for nonmedical purposs subject to the follo,.w ing: 1. Table I of ANSI N543 lists maximum permissible dose lirmts. In lieu of those listed limits, the user of this guide should refer to the dose limits prescribed by 10 CFR Part 20, -Standards for Protection Against Radiation." Every reasonable effort shoulc be made to maintain radiation exposures as far below these lirris as practicable.

of 10 CFR P.j, r 20 which provides that does levels of either 5 mhlirenis in any one hour or 100 miliirems in any 5 c,,iseculive days may be used to determine a radiaarea 5. Ii addition to the rate of exposure provisions in paragraph
3.3.3 of ANSI N543, the user of this guide is directed to the requirements of 10 CFR 20.105, "Per-missible Levels of Radiation Exposure in Unre stricted Areas." The requirements of §20.105 should also be considered when applying Appendix B of ANSI N543, "Determination of Gamma Ray Shield ing Barrier Thicknesses."
6. Piragraph
6.5.2 of ANSI N543 permits the use of a suitable lock in place of an interlock for a temporary exposure room. The user of this guide should comply with the specific provisions of §§20.203(cX2Xiii)
and 2O.203(cX4)
of 10 CFR Part 20 if he elects to use a lock in place of an interlock.
7. Paragraph
7.2 of ANSI N543 lists cqanges which require a radiation protection resurvey or reevalua tion by a qualified expert. A resurvey or reevaluation should also be performed when a change in radiation source may have adversely affected radiation protec tion.
8. Paragraph
8.4.6 of ANSI N543 recommends consider ation of the guidance provided in ANSI N13.6-1966(R1972), "American National Standard Practice for Occupational Radiation Exposure Records Systems." The user of this guide should also consider Regulatory Guide 8.7, "Occupational Radia tion Exposure Records Systems," which provides an acceptable definition of "bioassay" and notes that records must be maintained in accordance with §20.401 of 10 CFR Part 20. 9. Appendix A of ANSI N543 proides guidance for planning shielding where adequate occupancy data are not available or when complete installation use data are not available.
Persons using the occupancy factors and use factors in Appendix A for planning purposes should make appropriate observations and records to substantiate use of factors less than 1.2 L
