8 Best Radon Detectors to Protect Your Health

You cannot see, touch, or smell it; But radon gas is the second leading cause of lung cancer after cigarette smoking, killing more than 20,000 people each year. Radon is a radioactive gas that occurs naturally and is present in the soil, rocks, and water, as the breakdown of uranium. 

This toxic gas sometimes gets concentrated in homes constructed on soil having natural uranium deposits. It seeps through floor and wall cracks, construction joints, and even through electrical wires. As per the Environmental Protection Agency (EPA), 1 in every 15 homes in the United States has a high radon concentration of 4 picocuries per liter (pCi/L). Also, EPA estimates that any level of radon equal to or more than 4pCi/L is hazardous.

How to Detect Radon Gas?

The fact that radon is invisible and odorless makes it hard to detect and therefore more lethal. Like Rachael Malmberg, who was diagnosed with lung cancer due to persistent radon exposure, most households are unaware that they live in an area vulnerable to radon.

This exposes them to it for a prolonged period of time, which results in health issues like lung cancer. You can check the radon status of your area using this Radon map

There are two primary methods of radon detection:

  • Passive Radon testing 

This type of testing employs chemical or electromagnetic methods for radon detection and does not require a power source. It includes devices like charcoal canisters, electret ion chamber detectors, alpha-track detectors, etc. A radon test kit is used in typical passive tests, and the results are sent to experts for examination.

 Property owners can assess radon levels for a range of 2 to 90 days using these kits for short-term passive tests, or more than 90 days for long-term passive tests. The radon kit is then submitted to a laboratory, which evaluates the sample and delivers it to the property owner. These exams do not necessitate any special training so property owners can conduct them themselves.

  • Active Radon testing 

This type of testing is generally expensive and gives instantaneous results. It requires a power source to run and provides both short-term as well as long-term radon level detection. 

Why Do You Need a Radon Detector?

A recent study estimated that 34.1 million US adults currently smoke cigarettes. So, if you are a smoker and living in an area with high radon concentrations, you are at a very high risk of contracting lung cancer. Even if you don’t smoke, you should know that radon has resulted in six times more deaths than traffic accidents and the AIDS virus.

Using a radon detector in your home or workplace will enable you to detect the levels of this noxious gas and take the necessary steps to eliminate it and prevent exposure. One way of reducing exposure is to seal or vent areas where high radon levels are detected. But this is possible only if you are aware of the radon levels.

Busting the Myths Around Radon Detectors

There are several myths surrounding radon, so it’s critical to know the truth. After all, having only a little knowledge is riskier than not knowing at all. There are three common misconceptions to be aware of.

  1. Some individuals believe that radon testing is a laborious and time-consuming process. The truth is that active radon detectors enable accurate detection in a short amount of time and even sound an alarm if it reaches dangerous levels. 
  2. Another prevalent misconception is that radon is found only in specific areas of a country or specific types of houses. However, radon doesn’t care where it shows up. Your radon levels are unaffected by the sort of house you live in. It doesn’t matter whether your home is old or new, draughty or well-insulated, you can have problems with this gas. The geology surrounding your home, as well as the materials and the procedure employed in its construction, all have an impact on radon levels.
  3. Some people believe that testing for radon is pointless if they have lived in their house for a long period. Even if no one has fallen ill as a result of radon exposure, it is still necessary to test for it. You can lower your chances of developing lung cancer by doing so.

Tips & Advice for Choosing & Using Radon Detectors

  1. Before you buy a business or a home radon detector, it is critical to consider its accuracy. To get reliable results, you must ensure that it can deter interferences, else it might not meet its objective. 
  2. During short-term tests lasting up to seven days, always keep the house closed. Use your home’s heating/cooling system during the test. Use your air conditioner for testing that runs more than a week. This will assist in the recirculation of indoor air.
  3. Always read the user manual of the respective detector to avoid inefficiency and get better results.
  4. Don’t forget to send the kit to a certified lab if using a passive radon detector.
  5. A portable detector is the best choice for those who are frequently on the go and may not always have access to plug in your device. 
  6. A clear display of the readings is also necessary for proper analysis of the data. Some detectors come with LCDs while others let you view the data through a phone app. 
  7. Place the detector in a room that is closer to the ground, for example, the basement, for better results because the concentration of radon is highest near the Earth’s surface.
