What is Radon Testing, and Why Is It Necessary for Your Home

If you’re selling or buying a house, or if you’ve never tested your home for radon, this is your sign to conduct one. This is one of the great ways to protect yourself and your family from serious health concerns.

Radon is a radioactive, naturally occurring gas, and because of its sneaky nature, it is present in every home in the United States. It can sneak into your house through tiny cracks and holes, making it nearly impossible to detect.

Most of the homes in the U.S. have some amount of radon in their indoor environment. Meanwhile, the EPA estimates that 1 out of 15 homes have higher radon levels. This is quite alarming as prolonged exposure to radon can be a reason for devastating health effects. These effects can range from aggravated asthma symptoms to, worse, lung cancer.

Considering all of these associated risks, it is recommended by the EPA to test your home for radon. This should be done at least once every couple of years. Remember, radon is not predictable, but it is preventable.

This blog will cover all the important details about radon testing, highlighting its importance.  

Why Is Radon Testing Really Necessary?

Health Risks

One of the most important reasons for conducting a radon test is the linked health issues with radon exposure. Did you know that radon is the second leading cause of lung cancer in smokers? This is enough evidence to tell how deadly radon can be. With radon testing, you can identify and mitigate potential health hazards.

Invisible Threat

The risk becomes double if you can’t actually see the threat. Since radon is an odorless, colorless, and tasteless gas, it’s impossible to detect it without specialized equipment. For this, regular testing becomes an invaluable tool. It is the only way to determine the radon levels within an indoor environment. If they’re higher than the recommended levels (4pCi/L), then it’s time to perform remediation measures.

Varying Radon Levels

Radon concentration can vary from one location to another. In fact, if you test for radon in two different areas in the same building, even then, the levels can vary. Generally, you can expect higher levels of radon at such places:

  • Basements or lower levels
  • Older buildings
  • Mining areas
  • Water resources
  • Well-insulated and tightly sealed buildings

Once you conduct a radon test, you get accurate data on radon levels specific to a particular area. With this, you can determine your future steps. This can also help you make informed decisions.

Regulatory Compliance

In many regions, radon testing comes as a requirement for real estate transactions. And for certain types of buildings like schools and workplaces. So, if you want to have seamless real estate transactions and save yourself from legal issues, radon testing is one way to do that.

Peace of Mind

Whether you’re a homebuyer, home seller, or a homeowner, you need to take proactive actions to save your home from significant threats. Conducting radon tests can help protect your health and also your home from compromised indoor air quality.

How to Test for Radon?

There are different testing kits that you can use to test for radon. Here’s an overview of those.

Short-Term Radon Test Kit

You can DIY a radon test by using a short-term test kit. These can provide you with a quick assessment over a period of two to seven days. It could be available at any home improvement center or local hardware store. These might seem like a cost-effective option, but they definitely aren’t accurate. If you want accuracy, then nothing is better than professional testing. Not only have the professionals had better testing equipment. But they also know where to appropriately place the kit to get the best results.

Each home has its unique features and designs. Meanwhile, local and state law also sets different regulatory standards on how to place the equipment effectively. All of this is to ensure accurate results. However, when conducting a DIY test, you’re at risk of faulty tests. In fact, you won’t have the assistance to read the results or determine the next steps for mitigation.

Continuous Radon Tests

These tests are conducted using monitors that continuously run, measuring the radon concentration over an extended period. Typically, the time period is 48 hours. Professional inspectors will strategically place the device(s) to capture accurate results. The device will continuously monitor radon levels for two days. It will also attempt to eliminate or reduce measurement noise or interference that can result in inaccurate results.

After two days, the device is collected. And the inspector generates a report with the results.

Tip: Make sure not to touch or tamper with the monitor for the span of two days.

Long-Term Radon Tests

These are other tests that you can use for DIY-ing the radon tests. However, if we compare these tests, they are more accurate than short-term ones. This is because these use alpha particle tracking to determine radon levels. The device tracks the radon levels, collecting the alpha particles coming from radon gas. These tests last for a minimum of three months and a maximum of a year. If your house is located in a high-risk region, it’s better to go with a long-term test.

To gain peace of mind and get the most accurate results, you need to schedule a professional radon test. We’d recommend conducting a continuous radon test as it offers quick and accurate results. A qualified inspector will know where to place the testing device and get the best result. They’d also be thorough and will follow compliance.


Radon testing is an important step that ensures your home’s safety and your family’s well-being. These tests help measure radon levels, giving you insights about the potential health risks you’re breathing in. This puts you in an ideal position to take proactive steps and mitigate the risks.

Whether you choose to DIY your way through radon or go with our recommendation and schedule a professional test. You get valuable information that empowers you to make informed decisions about your indoor air quality.

This isn’t just about following regulations and ticking boxes. It’s about protecting the ones you love and creating spaces where there’s no threat of unseen dangers.
