Radon gets into your home through cracks in solid floors, construction joints, cracks in walls, gaps in suspended floors, gaps around services pipes, cavities inside walls and through your water supply. the gas is put off by the decay of uranium in the soil underneath and around your home. The gas rises up into your home through the cracks and unnoticeable lesions in the foundation and structure of your home. The gas then gets trapped inside of your home and over time can build up. In every ten homes throughout Iowa 5-7 of them have radon levels above 4pCi/L, the level of radon at which the EPA recommends having a certified contractor mitigate the problem.
Many children spend on average 70% more time in their home that their adult counterparts, so even though you may be out of your home with high levels of radon in it your children are not.
2 Ways to Test
Short Term Testing
Short term radon testing is the fastest way to test for radon in your home. Depending on the device testing can take two days to 90 days. Radon levels are likely to vary from day to day and season to season so short term test are not as accurate as long term tests. It is recommended that two short term radon tests are conducted to see whether or not your home needs to be mitigated.
Long Term Testing
Long Term Testing occurs for more than 90 days. This testing form takes longer but gives you a better idea of your year round radon levels and a more accurate reading for your average radon level. Have a more accurate reading means that you can make the decision to mitigate and fix the radon problem confidently.
