When uranium decays it likes to take someone with it. This is not your normal explanation of its effect on people, but rather a look at the chain events. We will go from the creation of radon to the harm it causes to minimizing the chances of becoming one of the 22,000 people succumb to cancer every year due to it. First let’s understand how we get from this metallic element to the dangerous gas.
Through the process of its decay, U (uranium) releases radiation in the form of alpha particles. The release of these particles causes the element to change – it will go through six changes before becoming Rn or Radon. In this gaseous form, radon is also decaying and releasing particles.
The release of these particles from radon is of no concern unless they have been ingested or inhaled, where it becomes most destructive. They will penetrate cell walls causing damage to chromosomes making the cell or group of cells abnormal. These abnormalities give cells characteristics like hyperactive growth and division, protection against programmed cell death, or loss of respect for normal tissue boundaries. These characteristics are known as cancer.
Abnormalities in cells occur independently from this specific example and your body is designed to seek out any cell that was damaged for any number of reasons. However, like most security systems, an overwhelming number of attacks can cripple or overrun the systems put in place to protect the host. No differently, being exposed long-term to higher than normal concentrations of radon increases your risk for developing lung cancer. So where is this gas? Outside, it is everywhere in small concentrations but it is so widely dispersed that there is little to be feared. Where it builds in large concentrations are the places that don’t allow for that dispersal to happen.

EPA Official public service announcement for Radon
When released from the ground it can come from water obtained from wells, through seams into a basement, or through a dirt floor crawlspace. Even just plainly through the windows and doors once opened. Since it originates from the ground, it can even come out of the stone in a kitchen countertop. The highest concentrations of radon in a home are the basement and/or crawlspace and 1st floors due to their proximity to the ground.
Two of the three American Lung Association’s recommendations to counter this deadly gas are: 1) Source Control and 2) Ventilation. The third, for your reference, is Air Cleaning which cannot be applied here. The layman’s terms are basically to control off-gassing of radon around your home and exhaust this gas out of it before it has the opportunity to accumulate. Most homes with a below grade lower level have a sump pump and a fan unit can be hooked up to it to remove radon before it enters from below. The limitations are the proximity of the suction created as a sump well alone cannot reach the entire square footage of your floor. Above the lower level floor, a fan can expel air out of the foundation wall, however, only after radon has infiltrated the structure. Source control and ventilation to the fullest extent would call for the entire perimeter of the lower level floor to have air flow pulling radon outside and exhausting it at the roof level so it cannot reenter the home.

B-Dry Blue Canyon System at work
The only system currently able to boast the ability to accomplish this is the Blue Canyon Dual Ventilation System™. With its inclusion to the B-Dry System™ and the dead air space that it creates beneath the concrete floor, there is continuous collection and expulsion of radon before it penetrates from below. The system extends protection to the side foundation walls by opening the hollow cores and through the vacuum created beneath the concrete floor, it allows radon penetrating the foundation to be pulled out before entering the living area. The cutting edge system has offered exponentially better results than the EPA limit of 4.0 Pi/Cl of radon in homes by showing readings of 0.08 Pi/Cl for a Washington, DC resident. Others tested in Knoxville, TN tested at 0.19 Pi/Cl after the Blue Canyon Dual Ventilation System™ was installed.
