Summary

This study tests whether specially designed radon risk messages increase homeowners' intention to test for radon or fix high levels. Researchers will compare different message types among rural residents who have never tested their homes and those who tested high but haven't taken action. The goal is to find messages that effectively raise awareness and motivate protective steps against this cancer-causing gas.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Radon risk messaging materials
What this could lead to
If effective, these messages could prompt more homeowners to test for radon and take steps to reduce exposure, potentially lowering lung cancer risk.
What could go wrong
The study measures intention, not actual testing or mitigation, and results may vary across different groups. Message effectiveness can be limited by real-world barriers like cost or time.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 500 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

May 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
