买房时考虑氡气是怎么回事？

[kevin_than]

最近看了几个kanata 的房子，感觉很好。 一些朋友说kanata 的有些地方氡气含量偏高。能否请对此有了解的朋友在此解释一下？

Thanks a lot.

我查到这个链接有关氡气分布情况。好象渥太华周围氡气含量很低。图片如下，如果有兴趣，可以查看http://geoscape.nrcan.gc.ca/ottawa/radon_e.php
图中深蓝部分为高含量地区，浅蓝为低含量或无。KANATA好象在浅蓝地区。希望有哪位专业人士能给分析一下。

关于氡气

关于氡气，我想说几句供参考
< ONTARIO BUILIING CODE > PART 2。1。1。8。规定
IN ADDITION TO ALL OTHER REQUIREMENTS， A BUILDING IN THE FOLLOWING DESIGNATED AREAS SHALL BE DESIGNED AND CONSTRUCTION SO THAT THE ANNUAL AVERAGE CONCENTRATION OF RADON 222 DOES NOT EXCEED 250 MILLIBECQUERELS PER LITRE OF AIR AND THE ANNUAL AVERAGE CONCENTRATION OF THE SHORT LIVED DAUGHTERS OF RADON 222 DOES NOT EXCEED 0。02 WORKING LEVELS INSIDE THE BUILDING
(a) The TOWN OF ELLIOT LAKE IN THE TERRITORIAL DISTRICT OF ALGOMA，
(b) THE TOWNSHIP OF FARADAY IN THE COUNTY OF HASTINGS，
AND
(c) THE GEOGRAPHIC TOWN SHIP OF HYMAN IN THE TERRITORIAL DISTRICT OF SUDBURY。
安省对氡气有严格的测试，并且现在有相关的施工措施。到目前我还没查到任何资料显示KANATA有较重的氡气说法。

how to get tested for my house?

 

[marklin]

Just to give you guys some update on radon gas. I just had a test done on a potential house we are buying in Morgan's Grant last weekend, the results are way below the US standards. I had contacted several inspectors in the area prior to the inspection, and all said they'd never encountered any single home in Ottawa area that had a high level of radon gas.

The test was done by placing 2 test canisters in the house for few days, then they were sent back to the lab for analysis. It costs me $80 and was done through Mark Hodgson, a reputable inspector in CFC forum.

If anyone is interested in doing the test, you can either contact a home inspector or check the following site out, this is where the test results came from:

Found another reliable source for radon gas test, this is from Radiation Safety Institute of Canada, if anyone decide to give it a try, don't forget to post back any feedback or comment!

Happy living!

I kind of remember that not long ago the "Ask This Old House" program on the WPBS channel had an episode to answer a viewer's question about radon.

The viewer had found a higher level of radon in the basement. The tests showed that the level was 6 while the US EPA (Environment Protection Agency) standard is no greater than 4. The "Ask This Old House" program hired a special technician to help the viewer to fix the problem and the program recorded the entire process.

At first, the technician did several tests in the basement in order to find out where the radon came from. After he found the source spot, he dug a hole in the basement floor and put a pipe into the hole. The diameter of the pipe is very similar to that of the sewage pipe we see in our home. The pipe went out of the basement.

In the basement, the technician also installed a box, which is an automatic radon-monitoring system. If the radon level is higher than 1, the system will automatically start a fan to exhaust the air through the pipe. Thus, the radon level in the basement is always kept under 1. The whole system plus the installation costs less than $1,500 US (I don't remember the exact figure, I only remember it was more than $1,000 US but less than $1,500 US). At the end of the show, the viewer and his wife seemed very happy because the problem had completely been solved.

If you're really interested, you may want to write to WPBS and ask them to re-run that particular episode of "Ask This Old House", which they often do.

KANATA是全部浅蓝安全区域。见红圈。无论怎样大家都喜欢KANATA LAKE，一定是有道理的。
