What is Radon Gas?

You cannot see radon gas nor can you taste it or smell it. Being a radioactive gas it is best to avoid it as much as possible. We have exposure to radiation 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 above normal levels can have serious health consequences.

Radon is a natural gas that comes from decaying uranium contained within rocks and soil. The gas is all around us both inside and outdoors. The levels of radon found outdoors are always safe but there can be a health threat from Radon 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, the design of the building and the materials used to construct it, and the habits of the people that use the building. Two buildings side by side can have different levels of radon gas.

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 end up trapped in airways, and if this happens then they will emit radiation which includes alpha particles which are particularly dangerous.

Humans that come into contact with this radioactive dust on a regular basis face the possibility of tissue damage and even lung cancer. It is essential that you know if your home or a 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 comes from all across the United States and throughout the world. According to the EPA, one in fifteen homes in the United States have high levels of radon. 

Radon can enter your home in a number of 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 see if the amount of radon gas in a building is at a safe level or not.

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

Alternatively, a radon gas detector can measure the levels of radon detected per cubic meter of air. The unit of measurement here is becquerels and you will see this expressed in the form 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 the amount of radon in the air within a building. There are radon gas detectors for home use and also for 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 to test for a minimum period of a week for greater accuracy with your 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 the levels of radon present will vary each day and from one month to the next.

2.Short Term Detectors

You should obtain a short term radon detector if you are looking for immediate results rather than have to wait for 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 the problem of radon testing. Inside an alpha track detector is a polycarbonate plastic sheet. Air particles collect on the plastic sheets and make very small marks.

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

4. Charcoal Detector

If you are looking for an inexpensive radon gas detector then a charcoal canister version will provide you with a solution for the short term. 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 over the short term and the 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 the radon gas or decayed product so that you can send it off 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 are counted t determine the amount of radon present 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 will normally require 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. Basically, an active radon device continually monitors for the presence of radon. They tend to be more expensive than passive devices.


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

There are a number of things that you need to take into account before you purchase 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 provide more accurate radon level results than short term testing.

How easy is it to use the radon gas tester? Most of the home testing kits are very simple to use but if you want to go for the continuous active testers then some of these 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 think about whether a one-off test is acceptable to you or you want to go for the added protection of continuous testing. A continuous radon monitor is certainly going to cost a lot more than a one-off test kit so you need to think long term here.

Although the price is another important issue you need to think about the benefits that radon monitors for home use will bring. Protecting the health of you and your family is far more important than a few dollars so please take this into consideration. It is better to pay for higher quality results and constant monitoring than worry about saving money.

First, we took a look at the accuracy of the Corentium Home Radon Detector by Airthings. We compared the results that this radon gas monitor displayed with a test kit that was sent off to a lab for analysis. The accuracy levels were very good and compared well with the lab results.

The manufacturers claim that this home radon detector has a “measurement uncertainty” factor of lower than 20% when used for a week’s worth of testing and this improves to less than 10% when the device continuously tests for a month.

You will be able to see both the long-term average results as well as the short-term average results clearly on the LED screen. For the short-term results, the number of days is also displayed.

It is really easy to use the Corentium Home Radon Detector by Airthings. The device is a no-nonsense radon gas detector that has only 2 buttons at the back which rarely needs to be used. All you need to do is decide on the location of the device and then turn it on. There are 3 AA-size batteries required for operation and these should last for around two years.

You will find a small keyhole at the back of the device which you can use to mount it on a wall. Otherwise, you can just stand the tester up against an object and it will work tirelessly. With its black and silver color scheme, it will fit in with any kind of decor.

Bluetooth connectivity will work some distance away. In our tests, we found that even 60 feet away and on other floors of a building we could still connect. If you want to move the tester to another room you can reset it to start testing again from scratch. It is possible to sync more than one Airthings Wave Smart Radon Detector with your useful mobile app.

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 radon sensor or electronic radon sensor then you need to monitor the results you receive regularly. With a passive or test kit you will have to send the device to a laboratory for radon-level testing after a specific amount of time.


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 then be sure to add new batteries to it. Usually, the manufacturer will specify how long 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 a basement exists in your home then 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 so leave them installed for a few days and then check the readings afterward.

There is nothing complicated about the installation of 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 so that you will get the most accurate results.


Frequently Asked Questions for Best Radon Gas Detectors: FAQs

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 if you are exposed to it at 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 with 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 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 lower than 4 pCi/L are 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 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.
