Radon Awareness Week 2022

Radon Awareness Week: January 24-28, 2022

Radon is estimated to cause around 21,000 lung cancer deaths in the United States every year and is the second leading cause of lung cancer, according to the U.S Environmental Protection Agency (EPA). Radon is a naturally occurring radioactive gas that can get trapped in homes and buildings and expose the people who live and work inside, increasing their risk of developing lung cancer later in life. This risk is even higher among those who smoke cigarettes.

The good news is that exposures to high levels of radon are preventable. CDC’s 2022 Radon Awareness Week, observed on January 24-28, raises awareness about risks and encourages prevention by highlighting a different theme each day of the week. Partners are encouraged to use the social media messages below and include the hashtag #RadonAwarenessWeek.

Environmental Health Nexus Webinar for Radon Awareness Week

This webinar kicked off CDC’s 2022 Radon Awareness Week, observed on January 24-28. Subject matter experts highlighted the following topics:

  • Basic information on radon and how to test for and reduce radon in your home.
  • The combined risk of radon and cigarette smoking, including second-hand smoke.
  • A deep dive into data and guidance for healthcare providers.

View webinar recording and transcript.

In recognition of Radon Action Month, CDC will sponsor its first Radon Awareness Week January 25th – 29th, 2021.  The week’s theme Protect Yourself and Your Loved Ones from Radon focuses on the need to increase the public’s awareness about radon as a potential public health concern.

CDC’s Radiation Studies Program, in collaboration with CDC’s Environmental Public Health Tracking Program and Division of Cancer Prevention and Control, will highlight messages on understanding what radon is, the importance of testing homes to determine if there is a high level of radon, and steps to take to reduce radon levels in homes.

Each day the messages will focus on a different topic:

  • Monday—Get the facts about radon
  • Tuesday—Testing is the only way to know if your home has high radon levels
  • Wednesday—Take action to reduce high radon levels in your home
  • Thursday —Smoking and radon are a dangerous combination
  • Friday—Know the radon levels in your area
