标准摘要
[中文适用范围]： 本国际标准规定了用于警告存在来自高水平密封放射源的危险电离辐射水平的符号，如果处理不当，该辐射可能导致死亡或严重伤害。该符号旨在补充基本电离辐射符号 [ISO 361, ISO 7010:2003, 表 1（参考编号 W003）]，而非替代它，通过提供有关该源相关危险以及未受训或非知情公众必须远离该源的进一步信息。该符号建议与国际原子能机构（IAEA）第 1、2 和 3 类密封放射源一起使用。这些源被 IAEA 定义为具有导致死亡或严重伤害的能力。 [外文原描述]： ISO 21482:2007 specifies the symbol to warn of the presence of a dangerous level of ionizing radiation from a high-level sealed radioactive source that can cause death or serious injury if handled carelessly. This symbol is not intended to replace the basic ionizing radiation symbol (ISO 361), but to supplement it by providing further information on the danger associated with the source and the necessity for untrained or uninformed members of the public to stay away from it. This symbol is recommended for use with International Atomic Energy Agency (IAEA) Category 1, 2, and 3 sealed radioactive sources. These sources are defined by the IAEA as having the ability to cause death or serious injuries.
