Radon gas is found everywhere, it is a naturally occurring decay product of the breakdown of Uranium, hundreds of feet below the soil. As Uranium breaks down it is eventually converted to Radon-222, which is the form of Radon that is dangerous to us.

Radon is measured by PCi/L (picocuries per liter). Picocurie per liter (pCi/L): a unit of radioactivity corresponding to an average of one decay every 27 seconds in a volume of one liter, or 0.037 decays per second a liter of air or water:  1 pCi/L = 37 becquerels per cubic meter (Bq/m3).

Outdoor air contains a radon level between .1 – .3 pci/L. Most homes radon levels fall between 1 -3 pci/L. The EPA states any home testing over 4 pci/L must have a Radon Mitigation system installed to lower Radon levels.

Radon Gas is currently the second leading cause of Lung Cancer in the United States, with over 22,000 deaths associated with it annually.

Radalink is the best monitor available on the market today. Utilizing a pulsed ionization chamber that detects Radon-222 atoms, test results are often available one hour after collecting the monitor (during business hours).

The Radalink Aircat has several security monitors built in to monitor if the test was disturbed in any way. A gyroscope (for movement), humidity gauge (for open windows or doors), and an AC power monitor (for notifications if the monitor was unplugged during testing).

When results are below the action level, the buyer is protected by the industry’s only 120- day written guarantee—which actually pays toward the cost of mitigation.

Radalink is one of the few radon instrument manufacturers with devices that meet the EPA real estate device requirement for minimum sensitivity of at least 16 CPH/pCi/L.

The monitor is set-up at the lowest level of the home that is lived in, and runs for 48 hours. Once the  monitor is collected a report is emailed to you within 1 business day.
