t**l 发帖数: 206 | 1 房子地下室原先的radon level是5.0,高于4。找了个公司装了radon mitigation
system,把sump pump也seal了。装完后隔天开始用test kit测,kit放了三天,寄给检
测实验室后,收到的报告显示还有3.4。
安装公司保证的是降到4以下,因为那是EPA的标准。不过装的时候,他也提到根据经验
降到2以下没问题。所以现在感觉效果不是很理想。刚刚打过电话,安装公司首先提到
已经降到4以下。不过他说可以再做一次测试,假如结果相似,可以换强力些的风扇,
请问有经验的大侠,你们装过mitigation后,测试结果都有多少啊?这没有降到足够低
的原因是什么呢?如何和安装公司商讨这个问题,请问有何建议呀?
谢谢! |

Looking at a house, radon test for 3 days has 5.1, the house does not have

d****a 发帖数: 89 | 7 虽然radon花个1000多块,装个系统就好。但是你以后再出售这个房子的时候就需要在
disclosure form上写明房子曾经radon超标。下一个买家到底计较不计较,那就难说了

radon system不是钱的是, 是没必要, 而且 还要铺管道, 墙上屋顶打洞。,,
地下室, 只要半开一个小窗, 风扇不开都可,radon 立马就降下来。 |

荒唐
but as long as you cook and ventilate, the space is not fully enclosed.
because of that, there is no way to treat the radon in the living floor
because it is not air tight. all radon mitigation system work by creating a
vacuum under the basement. without air-tightness, you can't treat it. |
|
d*******3 发帖数: 6550 | 11 你不会不知道living floor的radon都是从地下室来的吧,地下室装了mitigation
system,living floor自然就不会有radon了。如果没有地下室的那就在Living floor
下面装,和地下室一个原理。

b***b 发帖数: 13249 | 15 如果真的喜欢这个房子,就不要纠结这点事了。可以重测一下Radon。
不过也有买家因为Radon mitigation退房的, 见过一次, 但是我认为是那个买家的借口而已。 |

h******l 发帖数: 112 | 16 Radon level is not constant, It changes season by season. You could check
the information on line for that. Also you could buy the digital Radon

If you want to use the basement, better have the migration system. |

Is this a problem for the area?

c****2 发帖数: 318 | 32 elevated radon is quite normal in Chicago area. The seller just needs to
install a fan in his basement to let the air flow out. Radon is heavier and
needs many many years to cumulate to high level above 4.0 in some low level
place like basement. It would be 0.* after installing the mitigation system.
You need to worry more about your neighbors whether they have problematic
kids. That is much harder problem to solve if you are unlucky to have a bad
new neighbor. just my 2 cents.

o**a 发帖数: 86 | 40 Hi all,
My basement radon reading was 3pCi/L, which is a tad high.Since my kid may
use the basement as a play ground, I plan to take deduction measures.I found
a long list of EPA certified radon mitigation companies in CT from a google
search. Seems that they will install a vacuum pump under the basement and
release the air on top of the roof. Has anyone ordered such service before?
Any particular company to recommend? Thanks a lot! |

S**********l 发帖数: 3835 | 41 最近看了一个房子,感觉还可以。disclosure里面写了有radon的问题,已经装了

有几个问题,
1.我们在ann arbor,这个radon是很普遍么?看得其他几个房子disclosure上都没写。
2.mitigation能解决多大问题。
3.这家用的是井水,那岂不是水里面也都是镭?水里面的镭没法弄掉吧。 |
