Radon Testing In Your Home?
Having a short-term continuous radon test is a critical part of your home buying investigative process. Having radon testing performed during your due diligence period provides you with health and safety information about this home and also if needed, the cost of mitigation can be considered in the purchasing process.
Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths.
I test for the presence of Radon with a continuous radon detector from RadStar. This monitor is fully AARST-NRPP certified, and uses a Radon Ionization Chamber, to precisely calculate the radon level.
During radon testing, the monitor is set up on the lowest, level of the home, and runs for 48 hours after this area has been closed off for 12 hrs prior. The monitor collects an hour by hour average of the radon concentration level in the home. The 48 hour average of the hour by hour readings, will be presented in an easily understood report.
What is Radon and Why You Should Test For Its Presence?
The following information was collected from the epa.gov website.
Radon gas molecules are estimated to cause 21 thousand deaths from lung cancer each year. When you breathe air containing radon, the radon emits bursts of radiation that can damage the DNA in your lung tissues. As a result, if this damage is not corrected by your body, cancer cells can begin to be generated. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths.
Radon is a cancer-causing, gas that comes from the natural (radioactive) breakdown of uranium in soil, rock, and water. Radon gas/molecules rise up out of the ground into the air around us. Radon can be found all over the U.S. It can get into any type of building — homes, offices, and schools. Nearly 1 out of every 15 homes in the U.S. is estimated to have elevated radon levels. Elevated levels of radon gas have been found in homes in our state.
How Does Radon Get Into Your Home?
Radon from soil gas is the main cause of radon problems. Radon gas typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up to harmful levels. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.
Homes but on slabs are often overlooked, because, we travel in and out of the home through front, back and garage doors and windows are often opened to let in fresh air for air exchange. Air exchange with the exterior prevents the buildup of harmful levels of Radon Gas. None the less, in the south most people seem to leave their windows closed and strictly run their HVAC systems, preventing any significant exchange of air with the exterior. Even if your home is on a slab you should have your radon levels checked.
Radon Testing. Test your home for radon!
Radon levels are measured in Picocuries per liter – pCi/L. Remediation should begin if your radon level is 4 pCi/L or higher.
Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced. Most homes through current technology can be reduced to 2 pCi/L.
Radon Testing is the only way to know if you and your family are at risk from radon.
EPA Map of Radon Zones
The following radon data is collected from the EPA’S Radon Map Data. This map is only an average and should not be used as a replacement for your homes radon testing. Individual homes can vary in radon levels within the same geographical area. Testing is the only way to know if you and your family are at risk from radon.
|Zone 1 counties have a predicted average indoor radon screening level greater than 4 pCi/L (pico curies per liter) (red zones)||Highest Potential|
|Zone 2 counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones)||Moderate Potential|
|Zone 3 counties have a predicted average indoor radon screening level less than 2 pCi/L (yellow zones)||Low Potential|
