Radon

Awareness campaigns are designed to attract public and individual attention to the pressing issue, inform, educate and encourage dialogue. They intend to make the public more aware of a problem and encourage people to change their behaviors. 
If I were given a chance to design a radon awareness campaign I would probably develop ads, which include infographics and ads that are humorous but encourage awareness. 

Here are a couple of examples I found in Google that represent my vision of radon awareness campaigns.
 
My target population will be primarily homeowners, which is why I would post those awareness materials in as many sites as possible: billboards, social media, TV, auto radio, magazines, and websites.  
Potential stakeholders are the American Lung Association, American Cancer Society and Cancer Prevention, Cancer Survivors, Local Public Health Centers, Certified Radon Testers and Mitigation Specialists, the California Department of Public Health, California Department of Housing and Community Development.
