Radon gas, a naturally occurring radioactive gas created by the decay of radium in soil and rocks, can break down into small particles that adhere to dust. This dust can be breathed into the lungs. Prolonged exposure (over years) to radon increases one’s risk of developing lung cancer. While outdoors the gas dissipates and is not a threat, indoors it can accumulate to levels that present a health hazard.
Over the last several years, comprehensive radon testing has been conducted at 551 sites within Housing buildings. Approximately 20 sites required remediation. That remediation, involving the installation of ventilation fans, has been completed. Follow-up testing is regularly conducted where remediation was performed. New sites will be tested and acted upon accordingly.
