Radon is a naturally occurring radioactive gas that can cause lung cancer in non-smoking individuals. It is not easy to detect without an accurate detector. The Ecosense EcoQube (EQ100) is a smartphone compatible radon tester that lets you monitor real-time radon levels on your phone. The companion app alerts you if radon levels go above your comfort level.
The EcoQube is WiFi connected. It has a compact design, so you can move it around easily. It comes with color-coded LED on the front to give you visual feedback. The device has a counting sensitivity of 30 counts per hour per pCi/L. It graphs data on your phone, so you can visually see how radon levels change with the weather.[where to get it]
