As radon decays, it changes into other radioactive elements. These elements can become trapped in the lungs as the radon decay process releases energy in the form of particles. Over the course of a lifetime, this process can damage lung tissue and increase the risk of lung cancer. The amount of time spent at home. Typically, radon gas moves up through the soil into your home through cracks in the foundation and walls, pores in hollow-block walls, and gaps in suspended floors and around service pipes.
Homes often draw in radon because of differences in pressure caused by a variety of factors.
Your home can trap radon inside, where it can build up to elevated levels. Radon can also be present in well water, which then is released into the air by showering or other water usage. In most cases, radon in water is a small risk compared to radon gas entering the home from the soil. Since you can't see, smell, feel or taste radon gas, you need specialized equipment to test for it. Test kits are available in some hardware stores and home improvement centers.
