Types of Radon Test Kits

EPA suggests the installation of a radon removal system when the radon level reading is beyond the acceptable value. Testing your home for high radon levels can be done in several different ways with radon test kits.

Short-Term Radon Test Kits

These kits are used for collecting the radon readings from your home between 2 and 90 days. Then, the kits are supposed to be sent to a laboratory for calculation of results that will be sent back to you. The lab fees and shipping charges are included with the kit at times, so you can check for the same when buying a kit. There are both long-term and short-term radon test kits available on the market where the former is more reliable as they test the radon level over a long period and give more accurate results. Short-term radon test kits are better for quick testing and results.

Long-Term Radon Test Kits

These test kits are developed for testing the radon level in the house over an extended period. At the end of the usage period, the sample is collected and tested in the laboratory. This type of test kit is more accurate than short-term kits as it allows the collection and review of larger data rather than results being influenced by random spikes (high or low), leading to incorrect test results.

Alpha-Track Radon Test Kits

This is a long-term testing method where polycarbonate plastic sheets are used. In this, the test kit needs to be kept at the lowest livable point of the house to check the presence of radon gas. If the radon is present, then you’ll see tracks being created on the sheet by the alpha particles. The higher the level of alpha tracks, the more the presence of high alpha particles and radon. After keeping the alpha-track test kit in place for the time suggested by the manufacturer, you can remove the sheets and send them to a lab for tests.

Charcoal Radon Test Kits

Another short-term procedure, charcoal radon test kits have an identical operation when compared to alpha-track test kits, but in this test kit, the radon gas is absorbed for 2 to 90 days before you can send it to the lab for results.

These tests are affordable and fast to measure radon levels in the home, but not that accurate because they are influenced by the spikes in radon levels as the sample is shipped from your home to the lab for testing.

Digital Radon Test Kits

These kits are also known as radon detectors and are very expensive compared to other test kits. Installing them can be a bit of a hassle, as every manufacturer has its own procedure. But these are relatively permanent as you can attach them to a wall and use a sensor to determine the presence of alpha particles in the surroundings. It features a digital display that provides continuous pCi/L reading without having to send the samples to a lab.

How to Choose The Best Radon Test Kit?

Every radon test kit works differently, so you must keep the following points in mind while selecting a radon test kit:


Accuracy is a key factor when deciding upon test radon levels. The accuracy of the results depends upon how long the test is carried out by the test kit. Reason being, the longer testing will let you find out the average level of pCi/L in the home without the influence of random high or low spikes. There is always a question about the accuracy of short-term radon tests because of their susceptibility to spikes in radon levels, which may ruin the average. Whereas, long-term test kits take a long time to collect readings, but that leads to better average radon levels in the home. Obviously, their cost is high and the time taken to take the samples is also longer, but the results are more accurate than short-term radon kits.


Test kits designed for radon are meant to be simple and easy to use. Kits that are not easy to use can provide inaccurate readings due to human error, whereas kits that are easier to use provide more accurate results.

There are several passive radon test kits available, including charcoal and alpha-track. Both are relatively simple to set up, though they require you to get your hands dirty during testing. You have to place them in a particular location to test the air, then take the results to a laboratory.

On the other hand, digital radon detectors are very easy to use once properly installed. These devices will update radon level readings from time to time for you to keep a constant check and take action in case there is an unusual reading. Some digital radon detectors are complex as well because of the features added by the manufacturer.

Ease of Installation

If you are looking for a test kit that you don’t have to monitor on a daily basis, then you should opt for a radon detector, which comes all the instructions you need to place the kit at the right place for accurate testing. Active radon test kits range from wall-mounted battery units to units compatible with smart home devices, which require properly setup before you could use them.

Wrapping Up

Radon is dangerous no doubt, but there is a way to detect this gas and take suitable action to prevent it from harming you and your family. So, it’s time to act promptly and buy a radon test kit from the list of best radon test kit consumer reports. Follow the instructions to check the presence of radon gas and send it to the lab for confirmation. Don’t take it casually, as it can cause severe health problems that can put you in mortal danger as well. Get a test kit now!
