How to Test for Radon?

http://www.hc-sc.gc.ca/ewh-semt/radiation/radon/testing-analyse-eng.php

Radon testing is relatively simple and inexpensive. Radon test devices canbe purchased by phone or over the internet and are available at some homeimprovement retailers across Canada. For more information on do- it-yourselfradon test kits contact Health Canada's Radiation Protection Bureau at [email protected]or 613-946-6384.

You can also hire a certified radon measurement professional to come andtest your home. Health Canada recognizes the Canadian certification program, http://file:///C:\\DOCUME~1\\ADMINI~1\\LOCALS~1\\Temp\\msohtmlclip1\\01\\clip_image001.gif http://www.c-nrpp.ca/CanadianNational Radon Proficiency Program[/url] (C-NRPP) 1-855-722-6777.Lists of certified Canadian measurement and mitigation professionals areavailable through the http://file:///C:\\DOCUME~1\\ADMINI~1\\LOCALS~1\\Temp\\msohtmlclip1\\01\\clip_image001.gif http://www.c-nrpp.ca/CanadianNational Radon Proficiency Program[/url].

The most popular long term radon detectors are the electret ion chamberand the alpha track detector. These devices areexposed to the air in a home for a specified period of time, and then sent to alaboratory for analysis. Radon is measured in units called"becquerels per cubic meter" (Bq/m?). It is not uncommon to see radonlevels in a house change by a factor of two to three or more over a one-dayperiod. Seasonal variations can be even more dramatic with the highest levelsusually experienced during the fall and winter months when air circulation andventilation is decreased. Since the radon concentration inside a home varies overtime, measurements gathered over a longer period of time are generallyconsidered to give a more accurate picture of the radon exposure. Health Canadarecommends that homes be tested for a minimum of three months, ideally duringthe winter months as the radon concentrations are usually representative atthis time.

When conducting the radon test yourself observe the manufacturer'sinstructions and the guidelines below when placing a radon detector in yourhome:

• Make the     measurement in the lowest lived-in area of your home. By lived-in     we mean; where you or a member of your family spends more than 4 hours per     day in that area.
• Avoid taking     measurements in the kitchen. The exhaust fan as well as humidity and     airborne particles from cooking may affect the accuracy of some types of     radon detectors. Also, avoid bathrooms since relatively little time is     spent in this room.
• Place the     detector where it will not be disturbed during the measurement period but     avoid small enclosed areas, such as a cupboard or closet.
• Do not place     the detector close to an outside wall or near a sump or floor drain.
• Avoid     locating the detector in drafts from heating or air conditioning vents,     near windows or doors, or sources of heat, such as stoves, fireplaces or     strong sunlight.
• Place the     detector a minimum of 50cm from any floor, wall or ceiling and more than     20cm from other objects.

Health Canada has developed standard protocols for radon http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/radon_homes-maisons/index-eng.phptesting in homes[/url], http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/radon_building-edifices/index-eng.phpschools and other large buildings[/url]. Theseprotocols provide detailed instructions and guidance to radon testing companiesand homeowners on how to perform a radon test. Health Canada recommends thathomes be tested for a minimum of three months, ideally in the fall / wintertimeframe. The cost of radon testing is approximately$50 to $100.

As part of the National Radon Program, Health Canada has completed a http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/survey-sondage/index-eng.phpCross-Canada residential radon survey[/url] in aneffort to gain a better understanding of radon concentrations in homes acrossCanada.

自己如何做氡气检测

氡气是一种无色、无味具有放射性的惰性气体。正因为它的这些特性，人体器官无法感觉到它的存在。但是，它具有放射性，会对人体产生危害。
关于氡气是如何产生的，以及它的危害，可查阅系列文章http://proenbiotest.ca/xiangguanwenzhang.php。 大家也可以Google 搜索一下，网上有很多这方面的资讯。

知道了氡气及其危害，接下来很自然想到的一个问题是，如何检测。

先来看看权威部门--------加拿大联邦卫生部，是怎么说的。
联邦卫生部网站上说（http://www.hc-sc.gc.ca/ewh-semt/radiation/radon/testing-analyse-eng.php ），居民可以让专业人员上门检测氡气或自己做检测。

让专业人员上门检测，当然省事，但不省钱。比如我是联邦卫生部认可的氡气检测专业人员，我上门服务要收取服务费，再加上检测的费用。

那么自己做呢？省钱。

自己做氡气检测，关键是要拿到检测氡气的探测器。
得到探测器的途径有这么几条：
1， 到店里买。The Home Depot 有卖。 $13.99+TAX （这是在2015-11-25查到的价格），便宜。但请注意，您付这么点钱还无法知道家里的氡气数值。需要把探测器寄回实验室，同时再寄上检测费，才能得到报告。至于检测费用，2013年的检测费是 $30.00。 所以总的费用是，$13.99+13.99*0.13+30.00+邮寄费，50多刀吧。
2， 网购。大家可以上这个网站：http://www.radiationsafety.ca/community/home-radon-testing， 网上付$ 55.00+TAX， 即 $62.15 ( 这是在2015-11-25查到的价格)，他们就把探测器寄给你。检测完后，再寄回去，然后他们再把报告EMAIL给你。所以总的费用是，$62.15+邮寄费，70 多刀吧。
3， 不用邮寄得结果
先说明一下，上面两条途径得到的设备是不一样的。 东西不一样，价钱也有差别。
上面两条途径的共同点是，你必须把设备邮寄回实验室。
理想情况是，实验室就在你家隔壁，拿个探测器回家，检测结束了再送回去分析，省了邮寄费，减少了中间环节，把外界影响因素降到了最低。

我们就是你家隔壁的实验室。

ProEnBioTest Inc. 服务于多伦多及周边地区，工作人员是联邦卫生部认可的氡气检测专业人员。 打电话与我们见面（416-818-3930），然后得到和第二条途径一样的探测器，检测完后交到我们手上，48小时内EMAIL结果。所有费用是$50.00+TAX,即$56.50.

关于氡气检测的费用，联邦卫生部网站上也有说明，$50 to $100 (这是在2015-11-25 查到的信息)。政府呼吁居民检测家中氡气浓度，费用也不高，让大家都做得起。
