Some occupational health and safety jurisdictions have adopted values for workers in general , or for workers in a specific industry e. The Carex Canada summary document on Radon lists these values.
You can also contact your local occupational health and safety jurisdiction to determine what values may apply in your situation. Although there is currently no regulation that governs an acceptable level of radon in Canadian homes, Health Canada, in partnership with the provinces and territories, has developed a guideline.
Indoor radon level is measured by air sampling and by alpha dosimetry using radon track etch dosimeters. A number of companies manufacture and sell measuring instruments. Since radon levels vary greatly from day to day, Health Canada recommends long-term sampling at least 3 months to get a more accurate reading.
Testing can be done by professionals or by using testing kits that can be purchased over the internet or from some home improvement stores. Be sure to follow the testing kit's instructions carefully to get accurate values. In many cases, a method called sub-slab depressurization is used. A pipe is installed through the basement sub-flooring that leads to an outside wall or to the roof. A small fan draws the radon from below the house and exhausts the radon before it can enter the home.
Other methods include to increase ventilation, or to seal major entry routes into the home. Effectiveness of each method will depend on how high the radon levels are, and the characteristics of each home.

The concentration of radon and radon progeny in the indoor air depends on: the amount of radium in the soil and the ease with which the radon it produces can move through soil and building walls where it can then mix with the room air.
There are several sources of exposure limits to note. The results of the survey are not meant to be used to determine radon risk potential. The potential alpha energy concentration…of any mixture of short-lived. The potential alpha energy concentration … can be also expressed in terms of the so-called equilibrium equivalent concentration of … radon.
The equilibrium equivalent concentration, corresponding to a non-equilibrium mixture of radon progeny in air, is the activity concentration of radon in radioactive equilibrium with its short-lived progeny that has the same potential alpha energy concentration … as the actual non-equilibrium mixture.
The SI unit of the equilibrium equivalent concentration is Bq m -3 …. Radon Measurements A becquerel is a measure of radioactivity. That is why radonmap. The free tool can be populated with a huge amount of sensors from around the world, available to everyone. It is free to use, updated daily, and has thousands of anonymized radon sensors from around the world. You can see yearly, monthly and approximate risk calculations in this easy-to-use, interactive map.
Seasonality, ventilation, structural changes and location all make a difference to radon levels, which result in you having different readings to your neighbors. The best way to know the air you are breathing is clean and safe is by monitoring long term, with a detector that will track changes so you don't have to think about it!
Zero would be the natural answer, except that radon is a naturally occurring, radioactive gas that is in the air all around us. It is unavoidable, and in high levels over long periods of time can be dangerous. Hence the need for a radon detector, as its colorless, odorless and invisible, only through monitoring will you be aware of the levels in the air.
Depending on the country, acceptable radon levels vary. Homes or structures measuring higher are advised to take remedial action to lower radon levels.
It is also thought that reducing levels to sub This makes it easy to get an overview of the air in your home. In addition, you can check in the Airthings app if the radon sensor is good green , fair amber or poor red. High radon levels can be fixed easily and simply.
Whether it is following easy radon reduction tips, increasing ventilation, performing DIY fixes or contacting a radon mitigator, radon gas levels can be improved dramatically. The first step is to monitor, so that you can be alerted to high levels and make small changes where necessary. A smart radon detector with quick and accurate results on your smartphone. Additionally, you can simply wave in front of the device to get a visual indication of your radon levels.
