Choosing A Radon Detector – What to Look For

What should you look for when choosing a radon detector? This section reveals some factors worth considering before making a purchasing decision. They include:

Accuracy

A radon detector’s accuracy should be the first factor you consider before putting your money down. This factor could make all the difference in a life and death situation because radon gas is invisible, so you can’t rely on your eyes when detecting it.

Therefore, it’s crucial you get a device that makes up for that shortcoming. At the same time, these devices aren’t infallible, so it isn’t uncommon to get the occasional false reading. As such, it’s best to get a detector with high accuracy.

Speed

Testing speed depends on the type of radon-detecting device you get. Single-use radon test kits take a week or so to detect radon. However, when you consider that you have to send them to a testing lab after, the time doubles. This shouldn’t be an issue when testing for radon in an unoccupied building. However, such a long testing time isn’t ideal in a residence.

In contrast, digital radon detectors can provide results in a couple of minutes. So, they’re ideal for testing occupied buildings for radon.

Ease-Of-Use

Time is of the essence when testing for radon, so you should consider how easy a detector is to use when making your choice. After all, you wouldn’t want to be fiddling with electronics and instructions for hours when your environment could be the scene of a radon gas leak.

The most desirable radon gas detectors are a plug-and-play affair, so they either use batteries or plug into electrical mains. Also, they don’t have complicated setups and can begin detecting radon in your environment once they have power.

Wrap Up

Radon exposure is one of the many causes of lung cancer, so it’s crucial that you quickly detect how much radon your environment has. In terms of accuracy, speed, and ease of use, the products we’ve discussed in this article are among the best options you can get to keep your environment safe.
