Weather and Radon Testing

I am often asked why I use the radon testing equipment I use when it is so much more expensive reducing the amount of income on every test compared to most of my competitors. There are many reasons but here is one you can see. The first chart is the effect of a major storm lasting days with heavy rain saturating the ground causing what we call a "lake effect". The second is a shorter duration storm. Interestingly, the second test was in a home with a new active radon mitigation system. Of further interest the first test was in a home which was tested years ago resulting in a low test. I consistently test in homes with past tests conducted using other testing equipment and find the former test to have been drastically inaccurate and the home to have high levels of radon present. With results like this a second test is required (at not cost) during acceptable weather conditions.

When considering a radon test for your home ask the following questions:

1. Does your testing system provide hourly radon level readings?
2. Is your testing system tamper resistant and how is that accomplished?
3. Does your testing system provide hourly readings of radon, barometric pressure, temperature and humidity? 
4. Does your testing system provide a detailed report with charts providing a clear understand of the radon level in your home and issues which may be effecting it?

I am only aware of one testing system which meets these standards. Those are the reasons I only use this system.
