Comparison of the Best Radon Gas Detectors with Reviews From Amazon in 2026

What is Radon Gas?

You cannot see, taste, or smell radon gas. Being a radioactive gas, it is best to avoid it whenever possible. We have radiation exposure every day of our lives, and radon accounts for 50% of that exposure. With normal levels of radiation, there is no harm to humans. But exposure to radon gas at levels above normal can have serious health consequences.

Radon is a naturally occurring gas that comes from the decay of uranium in rocks and soil. The gas is all around us, both inside and outdoors. The levels of radon outdoors are always safe, but radon can pose a health threat in buildings of all shapes and sizes. 

Different parts of the country are more likely to have higher levels of radon gas in their buildings than others. There are other factors, too, such as the type of land the building sits on, its design, the materials used to construct it, and the habits of the people who use it. Two buildings side by side can have different radon levels.

The Health Risks of Radon Gas

Radon will cause radioactive dust to enter the air. Any levels of radiation over safe levels pose a health threat. The radioactive dust generated by radon gas may become trapped in the airways, and if this happens, it will emit radiation, including particularly dangerous alpha particles.

Humans who come into contact with this radioactive dust regularly face the possibility of tissue damage and even lung cancer. You must know if your home or the building you work in represents a high risk to you. 

Exposure to harmful radon particles causes thousands of people to die every year. You will find radon and uranium in all parts of the United States and throughout the world. According to the EPA, one in 15 homes in the United States has high radon levels. 

Radon can enter your home in several ways. It can enter through cracks in your walls and floors, through wall cavities, and may even get into your water supply. The bottom line is that radon is a serious health threat to you and your family. You need to conduct a test to determine whether the radon gas level in a building is at a safe level.

You will see radon levels expressed in picocuries per liter of air pCi/L. A curie is the level of radiation within a single gram of radium. The amount of decay of radium is around 2.2 trillion disintegrations every minute. A picocurie represents this decay and is a trillionth of a curie. 

According to the EPA, anything around or above 4 pCi/L is a health hazard, and you will need to take action to reduce the amount of radon that you are exposed to. Even if radon levels are below 4 pCi/L, there is still a risk, and it is often very difficult to reduce radon levels in a house or other building below 2 pCi/L.

Alternatively, a radon gas detector can measure radon levels per cubic meter of air. The unit of measurement here is becquerels, which are expressed as Bq/m3. With this unit of measurement, a radon reading of around 100 Bq/m3 is generally considered safe.

What is a Radon Gas Detector?

A radon gas detector is a device used to measure radon levels in a building. There are radon gas detectors for home and professional use. The US Environmental Protection Agency (EPA), together with the Office of the Surgeon General, recommends that you test your home for the presence of radon.

Using a radon gas tester is not a one-off exercise. The levels of radon gas in your home or a building that you inhabit frequently can change often. You should use your radon gas detector for at least a week to achieve more accurate results.

You can conduct a shorter-term test of a couple of days if you need to gather results fast. But we recommend that you follow this up with another test in a few days. If you are prepared to test for longer periods (such as more than 3 months) then you will be able to see the average radon levels for your home or office building.

Types of Radon Gas Detectors

There are a few different types of radon gas detectors that you need to be aware of. We will take a look at the different types here:

1. Long-Term Detectors

Radon gas detectors deemed suitable for long-term testing provide a broad range of results. You need to use long-term radon testers for a minimum of 2 days up to 90 days and beyond. You will get the most concise readings from a long-term radon detector.

Long-term radon gas detectors provide you with an average reading over the time that they are being used, which a short-term detector will not. This is important because radon levels vary daily and from one month to the next.

2. Short-Term Detectors

You should obtain a short-term radon detector if you want immediate results rather than waiting weeks, as with a long-term detector. A short-term detector shows varying results and not an average, and the information presented is often different.

3. Alpha Track Detectors

You will see alpha track radon detectors commonly used for radon testing. The reason is that they provide a long-term solution to radon testing. Inside an alpha track detector is a polycarbonate plastic sheet. Air particles collect on the plastic sheets, leaving very small marks.

After testing with an alpha track detector for some time, a lab can analyze the polycarbonate sheets. The number of marks left on the sheets will indicate the levels of radon gas present in the home or other building.

4. Charcoal Detector

If you are looking for an inexpensive radon gas detector, a charcoal canister version will provide a short-term solution. Normally, charcoal canister radon detectors take between three and seven days to produce a result. A lab can assess the amount of radon present in the charcoal as it absorbs gas in the air.

5. Digital Detectors

You will get consistent and continuous radon test results with a digital radon detector, making it a good all-around choice. There is no requirement for you to send anything to a lab for testing, as you will see the results straight away. A digital detector can display results in the short and long term.

How do Radon Gas Detectors work?

A radon gas detector tests for the presence of radon gas or the products left behind after the radioactive decay of radon. You can choose between two different types of radon detectors, which are passive and active.

1. Passive Detectors

A passive radon detector device does not need any electrical power from batteries or mains power. The passive device will trap radon gas or its decay products so you can send them to a lab for radon level analysis.

You will find passive radon detectors in different forms:

• Alpha track
• Charcoal canister
• Charcoal liquid scintillation
• Electret ion

With alpha track devices, dangerous alpha particles mark the plastic sheets. A lab will use chemical treatments to make these marks visible, and then they will be counted to determine the amount of radon in the air.

Both the charcoal liquid scintillation and charcoal canister devices absorb radon particles in the charcoal. A lab can then test for radon levels by counting the particles using either a sodium iodine counter or a scintillation counter.

Electrets ion detectors have a statically charged Teflon disc. Each time a dangerous radon particle strikes the Teflon disc, the amount of electrical charge reduces. A lab measures the reduction in charge and calculates the radon level.

Short-term radon testing typically requires charcoal-based radon detectors. You will find the charcoal and alpha test detectors widely available, while the electret ion detectors are a specialized purchase. You will see passive detectors often referred to as radon gas test kits.

2. Active Detectors

An active device can be a continuous radon monitor or a continuous working level monitor. These devices need electrical power from the mains or batteries. An active radon device continuously monitors radon levels. They tend to be more expensive than passive devices.

Things to Consider before buying the Best Radon Gas Detector :(Buying Guide)

There are some things you need to consider before purchasing a radon gas tester. The most important of these is the accuracy of the results that you will receive from the test. Long-term testing tends to yield more accurate radon levels than short-term testing.

How easy is it to use the radon gas tester? Most home testing kits are very simple to use, but if you want to go for continuous active testers, some are more complicated to set up than others. If you want to be a professional radon tester, then a degree of setup is inevitable.

You need to decide whether a one-off test is acceptable to you or if you want the added protection of continuous testing. A continuous radon monitor will certainly cost a lot more than a one-off test kit, so you need to think long term here.

Although price is an important issue, you should also consider the benefits that radon monitors for home use offer. Protecting your and your family’s health is far more important than a few dollars, so please consider this. It is better to pay for higher-quality results and constant monitoring than to worry about saving money.

How to Use Radon Gas Detectors

You may need to use more than one radon gas detector in your home or office building to detect harmful radon levels. This is because a single tester may not have the range to detect harmful particles from another part of the building. Once the detector is in place, you just need to leave it there to do the job.

If you have a continuous or electronic radon sensor, you need to regularly monitor the results. With a passive or test kit, you will have to send the device to a laboratory for radon testing after a specified period.

How to install Radon Gas Testers/System

It is not difficult to install radon testing equipment. With a home radon detector, it should only take you a few minutes to set up and install. If your radon tester uses batteries, be sure to replace them. Usually, the manufacturer specifies how long the batteries will last in the device. You can use a battery tester to check the remaining charge in the batteries you are using.

If you have a house or are checking a small office building, then you will probably require two radon gas testers. It is unlikely that one tester will cover all areas of your home. Because radon emanates from the soil, you need to place one of the testers as close to the ground as possible.

If your home has a basement, place the radon detector there. In homes without a basement, install the testing device as close to the soil as possible. Install the other radon tester in a busy room, such as your living room.

Install radon gas detectors where they will not encounter any obstructions. Placing them on an interior wall is often best. Do not install a radon tester near the source of heat or in a place where you know that drafts exist. Both of these situations can lead to false-positive results, so do everything that you can to avoid this.

After you have installed your radon gas detector, just leave it alone. Don’t be tempted to play around with it after installation. Determine how long you will conduct the test if you are using short-term detectors. Radon monitors for home use continuously check for radon levels,s so leave them installed for a few days and then check the readings afterward.

There is nothing complicated about installing radon testers. You do not require any special skills to do it successfully. The most important thing is to position the testers in the right places to get the most accurate results.

Have a question? Find the answer here with our Radon Gas FAQs that specifically cater to the needs of homeowners

Q.1 What is radon gas?

Radon gas is harmful to your health when you are exposed to high levels. It is a naturally occurring gas formed by the decay of uranium in the soil and rocks.

Q.2 What are the health risks of radon gas?

Radon gas is the second biggest contributor to lung cancer in the United States after cigarette smoking. Thousands of people die from high levels of radon exposure in their homes and work buildings every year.

Q3. What is the unit of measurement for radon gas?

In the United States, this is measured in picocuries per liter of air (pCi/L). Other countries use becquerels per cubic meter of air Bq/m³.

Q4.What is a safe level of radon gas?

Radon levels below 4 pCi/L are considered safe in the United States. 100 Bq/m3 is generally considered safe elsewhere throughout the world.

Q5.What is the difference between an active and a passive radon gas detector?

An active radon gas detector requires a power source such as batteries or a mains supply to keep it working. A passive radon gas detector does not need any electrical supply. With passive detectors, you will need a laboratory to analyze the radon levels.

Q6.Is short-term or long-term radon gas testing better?

With long-term radon gas testing, you will get more accurate results. Radon levels tend to change frequently, often daily.

Q7.Is a digital radon detector better than a test kit?

Yes, it is because you have continuous monitoring of your home. It will cost you more money, though.
