Got Radon? The only way to know your home’s Radon level is to test

Got Radon? The only way to know your home’s Radon level is to test. Info here!

Radon gas occurs naturally.

It is present in nearly all soil and rock; you can't see, smell or taste it - but it's there.

Radon forms when uranium breaks down to radium, which in turn breaks down to form radon. As radon decays, it releases radioactive byproducts that are inhaled. Radon is the second-leading cause of lung cancer after smoking -- and the number one reason why non-smokers die of lung cancer. It's estimated to be responsible for over 21,000 deaths annually in the United States.

Radon enters a home through cracks in walls, basement floors, foundations and other openings. Once inside, radon can become trapped and build up to unsafe levels, especially in areas below ground-level. Nationwide it's estimated that 1 in every 15 homes has elevated radon levels. In the Portland / Vancouver area that number can skyrocket to 1 in 4 homes.

Find Freshwater Mussels
The City and Johnson Creek Watershed Council seek volunteers to come learn about these creatures and spend two hours searching for them from 10AM to 1:30PM on Saturday Aug. 6 in Gresham. All ages welcome.

Last year's survey results were astounding. Extensive beds of Western pearlshell mussels were identified. This, and finding four adult Coho salmon last fall, tells us the Gresham reaches of Johnson Creek are able to once again support these native fish. Probably in part due to the cleaning power of the mussels!
