Radon is a radioactive gas that can be found in any home, new or old. This toxic gas comes from decomposed uranium in the soil, and since it always moves from the ground into the air above, it often leaks into houses through cracks in the foundation. However, you cannot see, smell, or taste this gas, which means that even though it is dangerous and cancerous if it builds up in the home, it can never be detected unless special procedures are enforced, such as occasional radon testing.
Radon Testing This test can take on many forms for a variety of different purposes. If you are buying or selling a house, it is always a good idea to hire professionals to inspect the property. Although this is more expensive, these qualified experts have specialized equipment that actively analyze the gas levels within a couple of days and officially report this information to the prospective buys. However, the most common form of radon testing comes in passive kits that any homeowner can use themselves.
