Granite floors are widely renowned for their aesthetic appeal and durability. They are the preferred choice among homeowners for their exquisite appearance and easy maintenance.

However, recent studies have revealed that granite floors, countertops and other surfaces contain radon, a radioactive gas that is closely associated with lung cancer.

Radon in Granite

Granite, a naturally occurring stone, is formed from volcanic activity and decomposing radioactive materials. The radioactive elements in granite include uranium, thorium and radium, all of which undergo a process of decay and give off gas.

Radon is one of these gases and is a colorless, odorless and tasteless gas that is impossible to detect without specialized equipment.

A study conducted by the Environmental Protection Agency (EPA) found that granite surfaces can emit radon gas up to levels that exceed the outdoor air levels.

In fact, radon in granite surfaces accounts for a significant proportion of total radon exposure in the United States, with an estimated 1,800 cancer deaths attributed to it each year.

Health Risks of Radon Gas

Radiation is harmful to the body and can cause severe damage if not controlled. Radon gas, in particular, is known to cause lung cancer and is the second leading cause of lung cancer after cigarette smoking.

When radon gas is inhaled, it decays and releases tiny radioactive particles that damage the lung tissue, causing lung cancer over time. The risk of developing lung cancer depends on the level and duration of exposure, with smokers at higher risk than non-smokers.

Detection of Radon in Granite

Radon gas cannot be detected by human senses and requires specialized equipment to detect its presence. Homeowners can purchase testing kits for radon detection or hire professionals to conduct tests.

The EPA recommends that homes should be tested for radon every two years, and work environments should be tested every year to ensure the safety of workers.

Reducing Risks of Radon Exposure

The good news is that the risk of radon exposure can be reduced by taking precautionary measures. The EPA recommends that homeowners take the following steps to reduce the risk of radon exposure:.

Test homes for radon. If the levels are high, hire a professional to assess the situation and install a radon mitigation system.
Increase ventilation to allow for better air circulation.
Seal any cracks and gaps in the floors, walls and foundation that may allow radon gas to seep in.

Conclusion

Granite floors have been a popular choice among homeowners for their exquisite appearance and durability. However, recent studies have shown that they could be potentially harmful due to the presence of radon gas.

Radon in granite surfaces is the second leading cause of lung cancer after smoking. Homeowners need to take precautionary measures to reduce the risk of exposure to radon gas from their granite surfaces.

As always, prevention is key, and testing for radon and installing mitigation systems can help to reduce the risk and ensure safe living environments.
