Did you know radon levels fluctuate throughout the year? Keep reading to learn what you can do as radon levels increase in winter in Idaho.

What is radon?

Radon is a radioactive gas that rises from the ground when uranium decays. When it rises outdoors, it’s not much of a risk to those who breathe it in. However, when it rises indoors, concentrates, and is breathed in over a long period, it can cause lung cancer.

Why radon levels increase in the winter

During winter, the snow-capped ground reduces the amount of radon that can rise outside, leading to more radon rising indoors. Additionally, because the air is cold outside, most people shut their windows and doors, allowing less radon to escape the home. Finally, as warm air rises inside, a vacuum is created that pulls more radon out of the ground and inside the home.

What to do about winter radon levels

If you have only ever tested your home for radon in the summer, your next radon test should be completed in the winter. If you have never tested your home for radon, there’s no time like the present!

In the cold winter months, many Idahoans spend more time indoors to avoid the elements. Unfortunately, radon levels also surge indoors during the winter months, and Idaho residents need to make sure they are taking precautions to stay safe and healthy.

Why radon increases in the winter

When the ground freezes over, less radon can rise outside, and it therefore rises in higher concentrations indoors. Additionally, because the warmth in homes rises, it creates a phenomenon called “the stack effect” that pulls more air from the soil and into the home to equalize air. As if that wasn’t enough, to keep the chilly air outside, windows and doors stay shut tight, and the stack effect can increase even more. 

How to reduce radon in your home

It’s not uncommon for Idaho winters to last 5–6 months, which means there’s a significant amount of the year where radon exposure can increase. The most important thing you can do for the health of you and your loved ones is to test your home for radon.
