The purpose of a Radon Inspection is to determine Radon levels in the house by testing, and to provide a full report on conditions in the house that may promote high levels of radon. This service is valuable for initial assessment of Radon, confirmation of previous test results, or verification that an installed mitigation system is working properly.
Radon is the second leading cause of lung cancer deaths, next to smoking. It is a naturally occurring soil gas that is produced by the process of Uranium deteriorating, breaking down into other elements on its way to becoming lead over the course of many years. Uranium is present in all soil and all rocks in very minute amounts - that is why Radon levels can be high anywhere there is dirt, basically.
Radon is a very volatile gas, which means once it is created it does not stay Radon very long - it deteriorates and breaks down into other radioactive elements within a matter of days, and those elements are even more volatile and break down within hours and they produce elements that will break down within minutes. When you breathe in Radon, that whole process occurs inside your lungs. Every time a stage of deterioration occurs, radioactive energy is released; and it is that energy that can cause DNA mutations and cellular damage resulting in lung cancer.
Studies have shown that Radon is not necessarily more dangerous to children than it is to adults, but that smokers are up to 12x more likely to get lung cancer from Radon than non-smokers.
Radon does not have any short-term effects, you cannot see it, smell it or taste it, it won't make you feel sick. So, the only way to know it is there is by testing.
Approximately 30-50% of homes in Prince George have elevated levels of Radon (29% above 200 bq/m3, 53% above 100 bq/m3). The national average is 7% of houses having radon levels above 200 Bq/m3 (the "action" level in Canada), so it is very prevalent locally, due to the permeability of soil conditions. The average indoor levels of Radon are around 50 Bq/m3; but the thing about Radon is, there is NO "SAFE LEVEL". That is why every house needs a Radon Inspection.
