【居家厨房石材的 放射辐射和有害气体 与你的健康】

 

大理石大厦 建于1888年

内壁 地面 皆以大理石为主

这样的石头房子 和 奢华装修 实不多见

 

近年来 室内石材 主要是 花岗岩 granite 和 大理石 marble

其 释放的 射线和氡气 及其对人体健康的危害  日益引人关注

 

是的  花岗岩 辐射 射线, 且 是最穿透的 伽玛(r) 射线为主

人们其实 每日每时生存于 射线辐射中

阳光 水 土壤 食品都含有或多或少的 射线  不可避免

只是微量 小量的射线 无大碍 而已

氡 是放射元素 镭 的 衰变物 仍然具有射线性 最终衰变成 铅, 是一种无色 无味 无嗅 气体 有害人体

高浓度 长期暴露和吸入氡气 可引发肺癌等疾患

开窗换气 让氡气飞出 是必要的

一个厨房石材(花岗石 大理石)台面      其放射极微 几乎可忽略不计

整个室内 石材化 表面装修 亦非不可 ?

不过 余似乎更喜欢 砖头石灰等低放射 高通气性的建材用于室内表面处理实用
