The Colorado Department of Public Health and Environment (CDPHE) has announced the opening of the 2026 Colorado and National Radon Video and Poster contest. The initiative aims to engage students in raising awareness about indoor radon risks, with opportunities to win cash prizes and have their work distributed nationally.
“Radon is invisible, but the risk isn’t — and that’s where Colorado students come in,” said Jill Hunsaker Ryan, executive director of the Colorado Department of Public Health and Environment. “Radon is the leading cause of lung cancer among people who don’t smoke, and this contest lets students use their creativity to help families understand their risk, test their homes, and take simple steps to stay safe.”
Students can participate in either a poster or video contest. The poster competition is open to those aged 9-14, while the video category accepts entries from students aged 14-18. Eligible participants must be enrolled in public, private, territorial, Tribal, Department of Defense or home schools or be members of sponsoring clubs such as scouting or science groups. Only one entry per student is permitted.
Winners at the state level will receive $300 for first place, $200 for second place, and $100 for third place. Teachers of winning students also receive $100 each. Winning entries will be displayed on CDPHE’s website and shared through social media channels. State winners will advance to the national competition.
The annual contest is coordinated by CDPHE in partnership with the Conference of Radiation Control Program Directors and the U.S. Environmental Protection Agency. Entries are due by April 30, 2026.
Radon exposure is a significant health concern; it is a colorless and odorless radioactive gas responsible for about 500 lung cancer deaths annually in Colorado among non-smokers. Families can check their homes using radon test kits offered free by CDPHE while supplies last at www.coloradoradon.info.
Additional information on radon risks, discounted test kits, certified contractors, and details about the contest can be found on CDPHE’s website or by calling Colorado’s Radon Hotline at 1-800-846-3986.
