事故报告和新闻报导除外。因医疗或其他目地，依据国家规定的程序接触、使用放射性同位素等，不属于本通知范围。生活中不可避免的天然同位素、宇宙射线、阴极射线管电视机的X辐射等，也不属于本通知范围。

比如在我的CuteO₂-40-B型发动机的第一次试车中，就因为上述原因（以及密封问题）发生了壳体烧穿（具体情况请看我发的那个事故报告贴）。最合适固体推进剂的孔型，应该还是各种异形孔（比如星孔）

不知道请先看一下火箭燃料板块上置顶的Winter的典型固体火箭燃料名单及禁用名单【20200327修订版】包括评论），劝告新人一句，先学理论，别在那瞎搞，免得出问题，想听响请移步到tb上买四凯，还有，多看看事故报告吧
