Radon coverage gap

View Plus measures radon. Ambient One does not. Radon is a colorless, odorless radioactive gas — the second leading cause of lung cancer in the US (EPA). Because you cannot detect it without a sensor, this is a meaningful difference for long-term home health monitoring.

Radon is a naturally occurring, colorless, odorless radioactive gas that comes from the breakdown of rocks and soil. It enters homes through cracks in foundations and gaps such as around plumbing entry points. It is the leading cause of lung cancer among non-smokers and the second leading cause overall (US, EPA, and WHO). The EPA recommends fixing your home if the average radon level is consistently at 4 pCi/L or higher, and considering action if it is between 2 and 4 pCi/L. Because View Plus monitors radon continuously over time, it gives a more reliable picture of your exposure than a single short-term test kit. Ambient One does not measure radon.
