The Best Radon Detectors

Radon test kits are great, but they do not continuously monitor deadly radioactive gasses within your home. After all, gas levels fluctuate daily so monitoring indoor air quality 24/7 with realtime updates is a far better option, especially if you reside in a part of the US that experiences high levels of radon. Here we will review some of the best home radon detectors and answer some commonly asked questions about them.

What is a radon detector?

A radon detector, as the name suggests, detects radon levels at your home or business.

It differs from a test kit. The difference is that a test kit collects the gas atoms over a certain period, and gets sent to a lab where it will be analyzed and then you get those results back. A detector stays in your home and constantly monitors radon levels, which you can access any time in realtime. A detector system can also trigger an alarm or send notifications to your smartphone when and if these gasses reach dangerous levels.

Where to place the detector

Radon detector placement matters a lot, and it’s strongly recommended that you install it in the lowest liveable part of your home. This will usually be the ground floor or basement.

Also, make sure that the detector isn’t anywhere near doors or windows, because even the slightest breeze can dissipate the gasses and result in inaccurate readings.

Another important factor to consider is humidity levels. Too much humidity can give false readings, so if the area you want to install it in experiences high humidity you might want to get yourself a good dehumidifier system too.
