Test your home for radon
- The plan
- When I move in or before winter, I'll order a radon test kit and put it in the lowest room we use.
- How you'll know
- You have a result and know where it sits next to 100 and 148 Bq/m3 WHO, 2009 Korea JoongAng Daily.
Why
The WHO's reference level for indoor radon is 100 Bq/m3, and only a test tells you your own level WHO, 2009.
If it doesn't fit
Renting? Ask the landlord whether the building has been tested, and put your result into the app when you have one.
