For almost 70 years, RDC has been a privately held company offering high-quality radiation monitoring dosimeters, better known as x-ray badges, at competitive prices with no hidden fees. Our Mission: "We are the invisible guardians of the people who keep us safe."​ There’s a reason we’ve remained loyal to our mission and to each other—we believe in our work. The people who use our products, the people we help keep safe, are the very people who keep us all safe. It’s noble work they do, and we take our portion of it, their safety, very seriously. At the end of the day, living out our core values of Integrity, Quality, Safety and Generosity is why we’re in business.
