What is Radon?

Radon is a gas produced naturally by the breakdown of uranium in soils and rocks that occurs naturally in the environment. You can't see, smell or taste radon. When radon gas escapes from the ground into some confined spaces, like homes, radon can accumulate to relatively high levels and become a health hazard. Long-term exposure to high levels of radon in the home increases the risk of developing lung cancer.

What is the Safety Siren Pro?

The Safety Siren Pro is the only electronic digital radon gas detector on the market designed for use by homeowners. The Safety Siren Pro is an affordable solution for monitoring the radon level in home with an easy-to-read digital display. The detector can be set to display a short or long term average reading. When the level of radon becomes too high, the detector will trigger an audible alarm. This small, re-usable electronic device is a must-have item, for protecting your family and friends.

The safety siren detected high levels of radon in my house. I hired a professional to validate the reading, and the results were similar. A1 for accuracy.
