本文件涵盖了在辐射处理中使用辐射敏感指示剂（以下简称指示剂）的程序。这些指示剂可以是标签、纸张、墨水或包装材料，当暴露于电离辐射时会发生视觉变化（1-5）。 使用指示剂的目的是直观地确定产品是否经过辐照，而不是测量不同的剂量水平。 指示剂不是剂量计，不应用作适当剂量测定的替代品。其他ASTM和ISO/ASTM文件中提供了有关辐射处理剂量测定系统的信息（见ISO/ASTM指南51261）。 本文件并非旨在解决与其使用相关的所有安全问题（如有）。本文件的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 本文件是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

This document covers procedures for using radiationsensitive indicators (referred to hereafter as indicators) in radiation processing. These indicators may be labels, papers, inks or packaging materials which undergo a visual change when exposed to ionizing radiation (1-5). The purpose for using indicators is to determine visually whether or not a product has been irradiated, rather than to measure different dose levels. Indicators are not dosimeters and should not be used as a substitute for proper dosimetry. Information about dosimetry systems for radiation processing is provided in other ASTM and ISO/ASTM documents (see ISO/ASTM Guide 51261). This document 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 document to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. This document 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.
