First test results from March 8th, showed a radon level at 17,6. Installed radon mitigation system with equipment from and advise from Val and his company. System started on April 24,2013, did a follow up test on 5/10/2013 to 5/14/2013. Results back today showed the radon level has dropped to 1.4 pCi/l. Very happy with this. Many thanks to the guys at Healthy Air Solutions for your advice and equipment.
