As most people know who have done the 2 day charcoal ‘short term’ radon tests, it is advised that the house be closed up as much as possible and the natural time to do that is in the winter. So now that summer is here (80 degrees in Fairbanks this past week!) does that mean that the testing ‘season’ is over? No. In fact, this may the time to put a test in to get a broader idea of what an annual average of radon gas concentration is in your home, shop, or anywhere else where you spend a good amount of time daily. The avenue for this type of testing is a alpha track long term kit. These will go into the home for anywhere between 3 months or a year, and since you will not be absorbing radon gas into charcoal and then counting how many half lives (3.5 days for one) the concentration has diminished, you are able to have doors and windows closed or opened when you want as well as operate your fans to comfort level. With these kits, the lab will put a clear slide of plastic under a microscope from the kit and count the ‘skid marks’ alpha particle discharges leave behind when exposed to radon gas. If you are interested in putting such a kit in this month (or any other yet this summer), give a call to your local Cooperative Extension Office to pick one up ($25) with mailing label and postage. Or call Art on the radon hotline at 1-800-478-8324 for more information.
