5. Radon Gas
Radon gas is a deadly, cancer-causing gas, that many Americans don’t even know about. It’s odourless, tasteless, and invisible, which is what makes it so deadly; and the worst part is–it might be in your home. It has been known to cause lung cancer in over 21,000 Americans every year, and children are especially sensitive to radon due to their high respiration rates and rapidly dividing cells, according to Radon.com. Radon is a natural gas that occurs when uranium breaks down in the soil and enters the home through lower basement levels, and it’s estimated that over six million U.S. homes are infected. Luckily you can test for radon with at home kits, and by using online resources that show if you live in a radon zone.
