Section I - Purpose and Applicability I. PURPOSE AND APPLICABLITY This Implementation Guide (IG) provides an acceptable methodology for establishing and operating an occupational radiation protection record-keeping and reporting program that will comply with U.S. Department of Energy (DOE) requirements specified in Title 10 of the Code of Federal Regulations (CFR), Part 835, "Occupational Radiation Protection" (DOE, 1993a; hereinafter referred to as 10 CFR 835). For completeness, this IG also identifies applicable requirements and recommendations contained in DOE Order 5480.11, as amended,"Radiation Protection for Occupational Workers" (DOE, 1992a), DOE's "Radiological Control Manual" (DOE, 1994a; hereinafter referred to as the RCM (with the associated numbers denoting the article numbers), and secondary documents (American National Standards Institute (ANSI) Standards, etc.) invoked by these and other primary documents. The Appendix of this IG provides a cross-reference of the applicable material in 10 CFR 835, this IG, and the RCM. This IG amplifies the regulatory requirements of 10 CFR 835, which are enforceable under the provisions of Sections 223(c) and 234A of the Atomic Energy Act of 1954, as amended (AEC, 1954). The requirements and recommendations of the other DOE documents are enforceable through contractual or administrative means. Except for requirements mandated by a regulation, a contract, or by administrative means, the provisions in this IG are DOE's views on acceptable methods of program implementation and are not mandatory. Conformance with this guide will, however, create an inference of compliance with the related regulatory requirements. Alternate methods that are demonstrated to provide an equivalent or better level of protection are acceptable. Contractors are encouraged to go beyond the minimum requirements and to pursue excellence in their programs. The word "shall" is used in this IG to designate requirements from 10 CFR 835, DOE Orders, the RCM, and secondary documents invoked by them. The requirements of 10 CFR 835 are mandatory, except to the extent an exemption has been granted pursuant to 10 CFR 820, "Procedural Rules for DOE Nuclear Activities" (DOE, 1993b), and are identified by a bolded and underlined "shall." Requirements taken from DOE Orders and the RCM are mandatory to the extent they are invoked by a contract or through administrative means. Those facilities not subject to the requirements of 10 CFR 835 should substitute the corresponding DOE 5480.11 requirements. This IG is applicable to all DOE activities involving occupational exposure to ionizing radiation of DOE employees and/or DOE-contractor/subcontractor employees.
