Radon is a harmful gas that is odorless, colorless, and tasteless; hence its presence is entirely undetectable by humans. It naturally occurs in the soil and can be found everywhere in the world. In extreme cases, radon poisoning can lead to death, and people don’t realize it until it is too late.

In this article, we have gone through a whole host of these kits and have come out with what we hope to be a comprehensive list for choosing the best radon test kit for your home!

What Is Radon, and How Is It Harmful to Our Bodies?

Radon is a naturally occurring radioactive gas. It can cause lung cancer in humans. It is undetectable by humans, and in almost every breath, we breathe some amount of this gas.

The gas quickly disperses outdoors and is not harmful if left in the open. However, if it is trapped inside four walls, it can be fatal. 

If you have a home with a basement and the floor has a few cracks or holes, there are high radon presence chances. Fortunately, there are a few steps, which you can take to control and reduce its level. 

But before taking any step, you need to check its level for which you will need a test kit. This is why you should invest some time looking for the best radon test kit because it can be a life-saving tool for your loved ones.

Are Home Radon Test Kits Accurate?

If you go for an excellent radon test kit, you can rest assured that you will get accurate results. 

One thing you must always keep in mind is that radon has a volatile nature, and its level in your home can change drastically every day, which means that you should always buy a long-term test for detecting its presence and fluctuation in levels.

On the other hand, short-term tests can give excellent results provided, you are in a hurry, and if the last two-three days’ results are enough for you. Also, for a short test, you need to keep your doors and windows locked as much as possible. Avoid air conditioners or fans that bring in air from the outside.

Where Should You Place a Radon Detector?

Radon often enters from the soil underneath the basement, and the level of radon is generally high in the lower levels of buildings, such as the underground floors. Also, radon most likely enters through a crack or a hole. 

So if you have bedrooms, offices, etc. in the lowest levels of the building, place the radon detector in one of these rooms. You can also set the sensor in any of the frequently used rooms, even if these rooms are not in the lower levels of the building. 

Always place the detector in the breathing zone, at least two-six feet above the floor and away from sumps, exterior walls, drafts, doors, and windows.

What Are the Symptoms of Radon in Your Home?

Since humans cannot detect radon by themselves; therefore, even if you are breathing at a high radon level, there are no apparent signs. 

However, radon exposure signs and symptoms of lung cancer can include shortness of breath, coughing up blood, wheezing, chest pain, hoarseness, persistent cough, fatigue, loss of appetite, and weight loss.

Does Opening Windows Help in Getting Rid Of Radon?

Radon escapes and disperses quickly in the open air; hence, it is better to open the windows if radon’s presence is detected. When you open the windows, air circulation, and ventilation improve, which helps move radon out of the house. 

Opening windows is the first and the most crucial step in removing radon from home. However, opening windows is just a temporary solution.

Is It Ok to Live in a House With Radon?

It is never safe to live in a house with high levels of radon. It is a natural by-product of uranium, which is found in all types of soils. Therefore there is no way to avoid it. 

However, its levels are high in basements and floor levels closest to the land under your house. So, when you know there is no way to avoid it, it is better to get the home tested for its presence. Once its appearance it’s detected, you must take safety precautions immediately.

How to Get Rid Of Radon at Home?

There is no single method to get rid of radon, yet some conventional techniques include:

Removal of Radon Using Suction Pipes

In this technique, a suction pipe is inserted into the concrete slab below the home, which is emitting radon. Then a vent fan is used to draw away the gas and release it into the open air.

Encapsulating the Cracks and Holes

This method includes sealing the cracks and holes with a special plastic membrane and then using the suction pipe method to eradicate radon.


Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) is a machine that exchanges indoor air with outdoor air. You can also use this machine to reduce the levels of radon in the home.

What Should You Consider When Buying the Best Radon Test Kit for Your House?

It is essential to select the right Radon detection kit for your home since you know that you are putting you and your family’s lives in the hands of that kit. Here are a few things to consider when looking to buy a good read on detection kit for your family:


Since there is already a lot riding on what these radon detection kits can find, we need to be very sure of the results that they are producing. Accuracy is not a standalone measure. It also depends on the period taken by the detection kit to record the observation and to come out with the result.

That is why radon tests that are claiming to detect radon within a short period are typically unreliable and susceptible to spikes in data that can skew the results.

Continuous testing over a long period generally produces much better results, which you can rely upon to be completely accurate. However, the catch is that these tests are typically a lot more expensive, and sometimes, even after all that effort, the result may come out to be wrong.

Ease of Use

Test kits are designed to be executed by the homeowner there are usually created so that even a layman can use them without any hiccups.

Passive test kits require a lot of effort during testing, but on the other hand, are usually relatively easy to setup. You just need to put them in a particular place and then mail them over to the lab.

Active test kits are easy to install and give you constant updates which you can see for yourself as and when needed. However, in case you are installing such a kit for an older person, make sure that they are comfortable using all the features of the test kit, such as smartphone connectivity and digital dashboards. 

Sometimes all of this technology can be very confusing, especially for an older person.

Technical Know-How Needed

As discussed earlier as well, passive radon test kits are usually a pretty simple job to put in place, however, with active radon test kits, it might take a bit of involvement to set up. 

Especially if they are not battery-run or else require a smartphone or digital connectivity, just be sure that you are comfortable with all the technical know-how that is needed for installing these kits.

The kits are meant for your convenience, so make sure that they don’t end up becoming your headache!

Next, we discuss a few test kits which we have selected for you. You can choose any one of these and get your house tested.
