According to the EPA, a long term test is the best way to determine your exposure to radon during different seasons and living conditions in your home, providing a better estimate of your actual risk. The alpha track radon test kit remains in your home for a period of no less than eight (8) days and not to exceed one year, allowing you to measure the radon level under normal living conditions. An alpha track detector takes into account all the changes in weather that occur during the radon gas test period, as well as the changes in the way you occupy/use your house under differing weather conditions. Weather conditions and ventilation habits can influence the radon level in your house, and with this type of radon gas test you measure the way you actually live, opening and closing doors and windows any time you want and using mechanical ventilation as you normally do.

An alpha track detector operates on a very different principle than the charcoal-based short term radon test kit and provides a much better indication of your home's long term average radon level. Inside the unit is a piece of film that records the impacts (tracks) of alpha particles produced by the decay of radon and its decay by-product, polonium. At the end of the radon gas test period, the radon testing kit is sent in the pre-paid mailer to the laboratory, who counts the alpha tracks on the film, computes the radon concentration, and reports the analysis.

Easy to order, easy to set up. Since it is a long term test, I have not yet returned it to get the results,. Will update this review at a later date.

5 stars Radon Gas Detection
I had been looking for a long term radon test kit for a while and decided on this one. The reviews all seemed positive and, to me, it seemed as though fewer things could go wrong during the whole process to and from the Lab for analysis. At any rate, initial delivery was very fast taking only a few days to arrive after placing the order. Included instructions were very clear so now, after setup, all I have to do is wait. I'll probably let the test run about 7 or 8 mos so I can get a decent idea about what the result will show across several seasons. At that time I'll provide another update on the results and how all was handled.

5 stars radon test kit
I cannot honestly rate the device (though I cannot submit this review without a star rating)as I only just "installed" it, but it arrived quickly, with easy to understand and implement directions, and easy return instructions. The results will be pending by fall of 2019.

This item came with directions that made it easy to set up. I plan on leaving it in place for at least six months to get an accurate reading.

Why do I need to test for radon?

Radon comes from the natural (radioactive) breakdown of uranium in soil, rock, and water, entering the air you breathe. Radon is colorless and odorless. It can infiltrate any type of building - homes, offices, and schools - and build up to high levels. But you and your family will most likely receive your greatest exposure where you spend most of your time... your home.

It is estimated that radon causes many thousands of deaths each year because breathing air that contains radon can cause lung cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of contracting lung cancer is especially high.
