Can stormy weather change the radon level in a house?

Monday, June 25, 2018

Two kinds of bad weather can raise the radon levels in a home temporarily. A heavy rainstorm that saturates the top layer of soil will seal the surface from rising radon gas and it will tend to migrate to under a home, where the soil is still permeable. High winds can lower the air pressure inside a home and enhance the natural “stack effect” of a home to pull in more radon from the ground. 

   Doing a radon test during stormy weather will likely produce an abnormally high reading and is not recommended. We avoid radon testing when a storm is approaching the area.

    Also, see our blog post Will opening the windows reduce the radon level in a house? and Will the radon test come back sky-high in a house that has been empty and closed-up for months?
