Green Hills Crawlspace

I traveled up to Green Hills today to measure out this crawlspace. Although the owner did a nice job of laying down some thick plastic, radon levels remained unchanged in the living space above. Since radon measured below 15.0 pCi/L, I will propose the installation of a heat recovery ventilator (air exchanger).
