ROBIN Radon Sensor Connects to Fans and Ventilation Controls

Radon is a colorless and odorless natural radioactive gas that comes from the ground and is present everywhere on the surface of the earth. It is created from the chain of radioactive decay of uranium. Because it is a gas it rises to the surface when it forms.

Radon is the #1 cause of lung cancer in people who do not smoke and the #2 cause of lung cancer worldwide. According to the American Cancer Society, “Lung cancer is by far the leading cause of cancer death, making up almost 25% of all cancer deaths. Each year, more people die of lung cancer than of colon, breast, and prostate cancers combined.”

In the outdoors, radon gas becomes diluted and presents no health risk. This is not the case indoors - where radon seeps into homes and buildings though poorly ventilated interiors, such as foundation cracks, sump pumps, poorly sealed cable ducts, etc. In locations where ventilation or air renewal is insufficient, radon becomes highly concentrated and presents a significant risk of causing lung cancer. Therefore, basements, crawl spaces, and first floors are the most susceptible to high radon concentrations.

Higher radon levels can occur during the colder winter months when buildings and homes keep windows and doors closed or sealed to keep warm and conserve energy. Recent scientific research reveals that newer, energy efficient, homes that are designed to prevent the escape of air conditioning in the summer and heat during the winter can have high radon levels year-round.

Testing for radon is the first step to determining if a home or building has safe radon levels. Radon tests are easy to conduct and affordable. If radon levels come back at the actionable level, then improving the efficiency of indoor air ventilation can be performed by a professional radon mitigator.

Radon mitigation is not a DIY project. It is a serious and involved endeavor. There are many techniques to properly ventilate and mitigate a home or building for radon. Mitigation professionals have the certifications, training, and special equipment to determine where the radon is seeping into the structure and how to safely remediate it. It can be as simple as sealing cracks in floors and walls and increasing indoor ventilation to conducting positive indoor pressurization and/or subfloor depressurization or ventilation.
