精华 感谢“小地主”，uglyducking，Mikejia： 成功安装氡气排放设备

[shgcn]

I bought this fan:

It is very good and quiet. The radon level drop to around 15 from 400. However I bought all installation stuff and radon detectors from www.radondetect.ca

你是自己装的还是找人装的？

下一步就是解决人体自身的70 bq/Kg 的磷40辐射，这个比氡气猛得多，氡气是惰性气体，基本不溶于水，无法构成化合物，因此无法在人体内积累，但是，自然界普遍存在的磷40，是构成人体细胞膜和骨骼的重要组成部分，一直呆在体内辐射不停啊，不只是肺，累计所有细胞，组织以及器官，万分危险；要不先买几个大型离心机，造点无辐射的磷同位素来易筋洗髓？

不是说氡气会积累在肺部吗？到你这里咋不积累了？

 

[uglyducking]

氡气积累在肺部？有任何可能吗？惰性气体耶，化学性质极端稳定，无法构成化合物沉积。物理上也不溶于水喝油，再加上3.8天的半衰期，你让它怎么积累啊？上口气进去，下口气就出来了，而且少了不少。
只要人不在地下2公里采矿，根本就无需担心氡气。

Q. How can radon affect my health?

A. Radon gas and radon progeny in the air can be breathed into the lungs where they breakdown further and emit "alpha particles". Alpha particles release small bursts of energy which are absorbed by nearby lung tissue. This results in lung cell death or damage. When lung cells are damaged, they have the potential to result in cancer when they reproduce.

The only known health risk associated with exposure to high levels of radon in indoor air is an increased lifetime risk of developing lung cancer. The risk from radon exposure is long term and depends on the level of radon, how long a person is exposed and their smoking habits. If you are a smoker and are exposed to elevated levels of radon your risk of developing lung cancer increases significantly.

On average, 16% of lung cancer deaths are attributable to radon exposure in Canada. In 2006, an estimated 1,900 lung cancer deaths in Canada were due to radon exposure. Radon is the 2nd leading cause of lung cancer, after smoking.

Other than lung cancer, there is no evidence that radon exposure causes other harmful health effects such as any other form of cancer, respiratory diseases such as asthma, or symptoms such as persistent coughing or headaches.

钾-40都不怕，还怕氡？

没事儿吸两口？

We installed the fan. Rented some tools from Homedepot to make holes in the wall. We installed the fan from the sump pump area where most of Radon come out because we live in countryside. You can use the same tool to make a hole in the basement floor. Find some videos online to see how you can do it yourself.

如果您老想买氡气，我给你打折，折可以打到你以身相许，你懂的！

不过，不许你告我性骚扰。

你要男的以身相许，口味不轻啊！hongyong的语文是看大门教的，误解很多!估计你是想说楼主是卖氡气设备的。

看来，我当初应该加价，组织团购氡气设备。最近，CFC很流行加价组织团购。

好帖。mark之。谢谢分享！

应该去卡屯搞化学的论坛上讨论一下。坎屯都是干IT的，看了半天也不明白到底值不值得安个抽氡气的装备。

不值得。

 

[渥太华的狼]

不值得。

能详细的说明一下不？家里老婆孩子担心这个问题。

去化学论坛讨论，结论肯定是不值得啊。
其实很简单，有顾虑就测一下，超标，就装，不超标但是还不放心，也装，低，不装。有免费同学那样的高科技知识的，不装。

简单粗暴直接，懂了。多谢了。
