Most people never think about radon until a test comes back high. This module does the explaining before they call, then hands them to your estimate form. It drops into any site with one line of code, or we build the whole site around it.
Fig. 1 / how radon gets into a house, and how a system gets it out
Simplified for illustration. EPA action level 4.0 pCi/L, WHO reference level 2.7 pCi/L.
What we do
How it gets out.
Test the house, design the system, install it, test again to prove it worked. Press the green button under the figure to see what a system changes, or click through the steps.
Drag to the number on your test. No test yet? Mid teens is a common starting point in granite country.
Risk for
If nothing is done
22
lung cancer deaths per 1,000 people who live at 12.0 pCi/L for a lifetime
After mitigation
5
per 1,000 at 2.7 pCi/L, a common guaranteed level after mitigation. Most systems land well under that.
Risk figures interpolated from the EPA Citizen's Guide to Radon, which assumes lifetime exposure at that level. Guaranteed levels vary by starting number and construction; ask your mitigator what they put in writing.
