Radon is primarily known as a significant risk factor for lung cancer. This naturally occurring radioactive gas is produced during the decay of uranium in soil, rock, and water, and it can accumulate in buildings, especially in poorly ventilated areas such as basements.

When radon gas is inhaled, its radioactive particles can damage lung tissue, which increases the risk of lung cancer over time. In fact, radon exposure is considered the second leading cause of lung cancer after smoking, according to health authorities.

Understanding the relationship between radon exposure and lung cancer is crucial for radon measurement professionals. They play an important role in identifying and mitigating radon levels in residential and commercial properties to reduce the associated health risks. While radon exposure has been studied in relation to other cancers, its strongest association is with lung cancer, making it a critical focus in radon risk assessments and public health messages.
