那么,接受了机场地铁火车站的X射线扫描的食物会不会有辐射残留呢?

简单的回答是不会。关于这个问题,梅奥医学中心的放射科医生 Kelly Classic 表示,“这个问题里需要区分两种辐射,一种是辐射暴露,也就是物品或者你自己在扫描仪里接受射线照射,另一种是接触放射性物质。”

不过,如果接受大剂量的X射线辐射,细胞内就会产生一种被称为自由基广东11选5的分子,大量自由基对细胞有害。下文讲到的食品辐照消毒法就是靠这一招杀死细菌和其他有害生物的。

普通X射线扫描仪的辐射量是多少?会影响食物吗?

简单的说很少,并不会引发安全问题。

界卫生组织在1997年的一项研究确认,1万戈瑞内的辐射不会影响食物的安全性或营养价值。1万戈瑞相当于食品接受X射线检测时的辐射剂量的1千万倍。

换句话说,一个馅饼在接受检测时接触到的辐射量相当于一个人在一般环境里呆2.5个小时后接触到的辐射剂量。

如果你还是不放心,可以参照一下食品辐照的辐射剂量。

食品辐照(food irradiation)是利用X射线、伽马射线等辐射产生自由基,从而杀死食物里的细菌、寄生虫还有昆虫的方法。它的辐射功率比普通X射线检测仪高多了,一次食品辐照的辐射剂量大约是3000希沃特,差不多是X射线检测的10亿倍
