Radon is undetectable by human senses. It is an invisible, odorless, colorless gas that can seep into your home through the ground. Unfortunately, it is estimated that about 10% of all lung cancers worldwide are related to radon exposure¹.

Use radonmap.com as a guideline, a way in which to  see if high levels are common in your area. Seasonality, ventilation, structural changes and location all make a difference to radon levels, which may result in you having different readings to your neighbours. 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!

The common radon myth

Not all countries, states or cities are known to have high radon areas, but that does not mean that individual homes are automatically free of any radon risk. Remember, high radon levels have been found in homes situated in areas with generally low radon levels. You can use radonmap.com to help see radon readings from your local area.
