Why Radon is Dangerous

Most homeowners know about the dangers of smoke and carbon monoxide and have detectors in their homes to guard against those dangers. But not many homeowners know about radon and what it can do to their health.

It’s Common and Hard to Detect

Radon doesn’t have any smell or taste, so it’s impossible to detect without special testing. Meanwhile, the EPA estimates that 1 in every 15 homes in the U.S. has elevated levels of radon.

It’s Radioactive

Radon is a radioactive gas, which means breathing it in will expose you to radiation. Alpha radiation emitted from radon is similar to that of plutonium. Even small amounts of radon radiation are comparable to standing near a nuclear power plant or radioactive waste site.

It Causes Lung Cancer

Radon is the second leading cause of lung cancer in the United States, superseded only by tobacco use. It’s estimated that radon causes close to 20,000 lung cancer deaths each year.

Where Radon Comes From

maryland radon inspection in soil


Radon is a byproduct of the natural decay of uranium that is found inside the Earth’s crust all over the country, especially in granites and shales. Because it is a gas, radon travels up and eventually exits through the surface. It can then enter your home though foundation cracks, drains, sump pumps, poorly insulated joints, as well as any exposed soil, such as crawlspaces.

A portion of radon produced from uranium decay may remain under the ground and enter groundwater, which then can travel to your private well and enter your home when you open a faucet. The EPA estimates that about 5% of radon in a home comes from water. Ingestion of radon is considered less dangerous than inhalation, although minimal risk is still present.

Building Materials

Although radon off-gassing from building materials is minimal, it is often the fastest route for radon to get inside your home. Building and manufacturing materials such as concrete, gypsum board, granite and field stone have been known to emit small amounts of radon. Nowadays, builders are encouraged to use radon-resistant building techniques to minimize related health risks.
