Students Win Honors in Statewide Radon Poster Contest

Students from Boulder, Littleton, and Fort Collins took top honors in this year’s statewide Radon Poster Contest to raise awareness of health risks associated with radon gas. More than 250 students across Colorado participated in the contest. The top three Colorado posters will be entered in a national contest sponsored by the National Radon Program Services in conjunction with the U.S. Environmental Protection Agency.

First place was awarded to Chiara Calcao from Boulder. Her poster, “Child Saver” featured an artfully drawn child with a "save this child" message. Chiara is a student of Dawn Deming at Manhattan Middle School in Boulder.

“The state health department joins Chiara in urging Coloradans to test their homes for radon,” said Chrystine Kelley, radon program manager for the Colorado Department of Public Health and Environment (CDPHE). “It’s easy to do, and it’s the only sure way to tell whether or not your home is affected by radon, which occurs naturally in the soil.”

Radon Health Effects

  • Long-term exposure to radon - a colorless, odorless, tasteless radioactive gas - is the most frequent cause of lung cancer in non-smokers and the second leading cause of lung cancer in smokers. Exposure to radon is responsible for approximately 21,000 lung cancer deaths in the United States each year.
  • If considered independently from tobacco smoking, environmentally and occupationally-related causes of lung cancer are among the top ten causes of cancer mortality in the United States.
