Please Test for Radon to Protect Yourself and Your Family from Lung Cancer

Do you know what the second leading cause of lung cancer is, after smoking? It’s radon, an odorless gas that can seep into your home. Because it cannot be seen, tasted, or smelled, it can be easy to forget.

The fact is, though, that EPA, the U.S. Surgeon General, and multiple leading public health advocates have all announced that about 21,000 Americans each year die from radon-induced lung cancer. That should make headlines, right? You would expect people to demand that something be done to stop it from happening. The threat from radon is real and we make the announcement each year during National Radon Action Month. Many of our families have been tragically impacted by lung disease, and lung cancer is a heartbreaking diagnosis.

Testing is the only way to know if your family’s home has elevated radon. Nationally, one in 15 homes are above the level at which the U.S. Surgeon General and EPA recommend taking action, which is four picocuries per liter (pCi/L) of air. In many parts of the country high levels are even more common.

Mobile Apps and Our New Year’s Resolutions

By Carmen Torrent

In January, people reflect on their lives and make a list of things they want to get, change or strike out. The tradition of making resolutions comes from ancient times. The Roman Empire established January 1 as the beginning of the year and placed Janus, a mystic god, as the guardian of the door of the New Year, and he became the symbol of the resolution. Janus has two faces representing beginnings and endings, one looking to the past and the other to the future.

Topping my list of resolutions this year is to be healthier, and part of being healthier is to maintain a healthy home. That’s why I decided to test my home for radon. Now that I know radon is the number two cause of lung cancer behind smoking, testing for radon is a high priority for me. While it’s true that we all start the New Year determined to carry out our resolutions, I know that as time goes by some are forgotten. Like my grandmother used to say, “It’s easier said than done.” And I didn’t want to forget this important resolution, so I came up with an idea that would help me achieve my resolutions this year, and I get to have fun using my new smartphone.

I recorded my resolutions on my phone and then I used a mobile application to remind me of my new year’s resolutions: “How do I test for radon?” And the app sent me to find out how to test my home and what to do if I have high radon. Try it; it’s fun! Never thought that I would put this technology to good use to protect the environment.

January marks the beginnings in many ways, and it’s also designated by EPA as National Radon Action Month. Radon is a radioactive gas; it is invisible and odorless. Radon gas enter the lungs when you inhale, the radioactive particles damage your lung tissue and can cause lung cancer. You can have a healthier home simply by testing your home and taking the necessary actions to lower radon levels. The only way to know if you have radon in your home is to test, and what a better time to test than in the New Year? For more information on health risks, visit

Today let’s look to the future. Do not wait; test your home for radon and make the necessary repairs to your home, it could save your life.
