b'Michael Christophides, Chief Inspector and Laboratory Director of Granit Inspection Group, joins co-host Sarah O\\u2019Connell and guest co-host and physicist David Kruger to describe the hazards of the gas radon, which can accumulate in buildings or in well water. Radon is an odorless radioactive gas that is released from rocks of all kinds, but especially from granite or dark shales found in the Hudson Valley. Radon in the air is the second leading cause of lung cancer (and adds to the risk of cancer in smokers), while radon in water can increase the risk of stomach cancer and may also be released into the air. Testing is the only way that you can tell whether or not radon is present in dangerous levels. Mr. Christophides recommends testing every two years, since levels can change based on seismic activity, changes in structures, or other factors. If a test reveals excess radon, remediation usually consists of suctioning air away before it can enter the house.\\n\\n--- \\n\\nSupport this podcast: https://podcasters.spotify.com/pod/show/radiorotary/support'
