4.1 This guide covers types of materials to be examined, neutron radiographic examination techniques, neutron production and collimation methods, radiographic film, and converter screen selection. Within the present state of the neutron radiologic art, these practices are generally applicable to specific material combinations, processes, and techniques.View Less
1.3 Interpretation and Acceptance Standards-Interpreta
1.4 Safety Practices-General practices for personnel protection against neutron and associated radiation peculiar to the neutron radiologic process are discussed in Section 18. Jurisdictional nuclear regulations will also apply.
1.5 Other Aspects of the Neutron Radiographic Process-For many important aspects of neutron radiography such as technique, files, viewing of radiographs, storage of radiographs, film processing, and record keeping, refer to Guide E94, which covers these aspects for X-ray radiography. (See Section 2.)
1.6 The values stated in either SI or inch-pound units are to be regarded as the standard.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
