5 Best Home Radon Detector 2022

Breathing, Wellness

Carbon monoxide, nicotine in cigarette smoke, ammonia, and formaldehyde are known to be some of the most hazardous gases around the home. But not many people know the dangers of radon. The National Cancer Institute mentions that radon is one of the leading causes of lung cancer after cigarette smoke. Having a home radon detector can definitely help lower your chances of developing any side effects.

Radon accounts for up to 22,000 deaths resulting from lung cancer every year in the United States. According to the EPA, while radon is known to cause lung cancer, those who smoke are at a higher risk of developing lung cancer. For this reason, whether you are a homeowner or a tenant, it is essential to conduct a radon home test on a regular basis. 

While radon gas can occur anywhere, it appears at higher levels in the Midwest, Southwest, and northern states of the US.

When should you test for radon? 

  • Before buying or selling a house. 
  • Before buying or moving into a newly built home (it’s important to find out if radon-resistant materials were used during construction). 
  • Regularly in your place of work.

What is radon?

 

 

Radon in Homes and Where it Can Enter

Radon is an invisible, odorless radioactive gas found underground. It is a byproduct of uranium and thorium that occur naturally in the soil. Radon is released when these radioactive elements (uranium and thorium) decay. It then slowly seeps through the soil and into the air. Radon may not be hazardous when released into the open air as it gets diluted to safer levels. However, when released in buildings or enclosed areas, radon gas can be dangerous because it becomes concentrated.  

Since radon is a colorless and odorless gas, you may unknowingly inhale it whenever you’re inside. That’s why many people use a special kit to detect its presence and levels in their homes.

How is radon measured?

Radon is measured in picocuries per liter (pCi/L). The average concentration of radon gas indoors is about 1.3 pCi/L. While no level of radon concentration is considered safe, EPA recommends that indoor radon levels should be 4 pCi/L or lower. Lower radon gas levels can be maintained through proper ventilation and sealing of cracks. Sometimes installing radon pipes to channel radon gas outdoors works well too.  

It is essential to closely monitor the levels of radon gas indoors through regular testing. Higher levels of radon in your home or workplace require immediate mitigation action. Leaving it as is, can put both humans and animals at risk of developing lung cancer. It takes between 5 years and 25 years for one to develop cancer. Unfortunately, there is no cure for radon poisoning.

Some signs of radon poisoning are:  

  • Persistent coughing  
  • Coughing blood  
  • Wheezing  
  • Shortness of breath  
  • Chest pain  
  • Higher vulnerability to infections like pneumonia and bronchitis 

Note: If you develop any of these symptoms, seek medical help immediately.

Types of radon detectors 

Radon can be detected using radon detecting devices or radon detectors. You can install these gadgets indoors to continuously monitor the quality of air in the home. When radon concentration levels exceed the EPA’s recommended 4 pCi/L, the detector lets off a warning signal to notify the homeowners. 

There are two main types of radon detecting devices.

1. The passive radon detectors. 

The passive radon detector is manually operated and is generally the less expensive option. You can place these detectors in a specific site for several days before taking it to the laboratory for evaluation. Thus, it’s possible to perform periodic passive radon detection. Common passive radon detectors include charcoal canisters, charcoal liquid scintillation devices, Alpha-track detectors, and Electret ion chamber detectors. These devices use chemical or electromagnetic techniques to detect radon inside spaces. You may need to use several test kits for different spaces in the home.   

2. The active radon detectors 

Active radon detectors are electrical and are often more costly than their passive counterparts. However, they’re more accurate. Their design gives them the ability to continuously monitor radon levels in the home. For example, these detectors will typically display timed readings after every hour. Most of the radon detectors you’ll find in this article, fall under this category.   

It is important to note that there are areas that naturally have higher concentrations of radon. If you happen to reside in any of these areas, we recommend installing an active radon detector. On the other hand, if you live in an unfamiliar area and you’re unsure of the radon levels, you can first purchase a passive detector. This will monitor radon levels over time then you can invest in a more expensive kit.

Do home radon detectors really work? 

It depends on the device. The average radon level in the home usually ranges between 1.3 pCi/L and 2.5 pCi/L. A good radon detector should provide accurate readings, particularly for radon concentrations above 4 pCi/L. However, this is not always the case as some detectors can give false readings.  

The following factors determine how accurately a radon detector measures the concentration of radon in the home.  

  • Type of detector 

Generally, active radon detectors are usually more accurate than passive ones as they collect data consistently, over time. This provides accurate readings and will instantly detect unusual radon levels. 

  • Placement and movement 

The reason why many believe active detectors are more accurate is that the homeowner installs the detector in one position. It is advisable to have a certified radon professional assess your house to install the radon detector for you in the right place. Secondly, unlike the passive detectors, you don’t have to move active detectors from place to place. Thirdly, things like late shipping, movement during shipping, and wrong placement can affect the readings of a passive detector. 

  • Length of exposure  

It is also important to note that the longer a detector is exposed to the air in your home the more accurate the results it will provide. For instance, even after 10 minutes of installing the most reliable digital radon detectors, they will give more accurate readings over 1 hour or an extended period of time.

Where should a radon detector be placed?

The highest radon gas concentration usually occurs in the lowest level of your home in spaces like the basement, foundation, cellar, or construction joints. Mainly, it’s locations around the house where it’s in contact with the ground there’s less ventilation.  

Ideally, the type of detector you purchase and how long the test takes will determine its placement. It’s best to mount short-test radon detectors on walls or place them on a level surface above the ground in enclosed rooms. On the other hand, it’s better to place long-term radon detectors in the lowest levels of your home in rooms that lack proper ventilation. Also, be sure to follow the manufacturer’s instructions for mounting your radon detector.  

Here are some tips when mounting radon detectors: 

  • Avoid humid places like the laundry room and bathroom. 
  • While crawl spaces and construction joists often have higher radon concentrations, they are not the best places to mount your detector as it is bound to pick up false readings.  
  • Often document the readings for tests that run for more than 72 hours.

What should you consider when buying a radon detector for your home?

As we have already seen, the best home radon detector is the one that runs continuously and monitors radon concentration for days or months. Even so, it should be displaying accurate readings all throughout the tests. Here is what you should consider when buying a radon detector for your home: 

Accuracy level 

You need accurate, reliable readings which require not just an accurate device but one whose readings will not be interfered with by the surrounding environment. Inaccurate results could be risky to you and your loved ones because of high radon concentrations in your home. Without a radon detector, it’s hard to know when the radon concentration reaches toxic levels.  

Also, the longer the kit is exposed, the more accurate the reading and subsequent analysis will be. This is because you will have more data to determine the average radon level in your home.  

Some things to keep in mind:   

  • If you are using the short-term radon test kits, be sure that the room is fully closed up with no open windows and doors for the most accurate results.  
  • Properly place and install long-term kits in your home.  
  • Always mount your test kit at least 20 inches above the floor on a stable surface.  
  • Avoid mounting it in places with high humidity or near interference by external environmental elements like heavy wind and temperature.  

Portability of the device  

Is your device battery-powered or do you need to connect it to a power outlet? Some places may not have an electric power outlet to plug your radon kit. In this case, a battery-powered radon detector comes in handy.  

How large is your radon testing kit?  Some detectors are moved from place to place to test different properties. Thus, a sizeable detector that fits your pocket can be convenient to carry around.   

Data access  

This refers to how easy it is for you to access the readings on your radon kit. If you are using the short-term test kits, how easily can you get the results from the laboratory that will analyze its readings?  

On the other hand, some long-term digital test kits come with Bluetooth or wireless connectivity. This allows you to access the readings and analysis from an app on your smartphone without having to go to the device itself or wait for the lab results. This is more convenient as you will get instant alerts to toxic radon levels.
