Frequently asked questions

Both devices measure radon. X-Sense XR0A-SR measures radon.

X-Sense XR0A-SR: Not available — on-device LCD display only.

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 both of these devices monitor radon continuously over time, they give a more reliable picture of your exposure than a single short-term test kit.
