Summary
Brief summary (as posted)
This research will compare (1) the effectiveness of a mobile radon-education app (vs. traditional brochures) and (2) that of the radon app with in-app reminders (vs. the radon app without in-app reminders and the no app use with postal reminders) to increase radon awareness and testing among North Dakotans. The prevalence of exceptionally high levels of residential radon in North Dakota (ND), coupled with public's poor understanding of this hazard, is a critical public health problem.
