Which dentist from Boston is known as the Father of Radiation Protection?

• A. Gustav Peter Bucky
• B. Hollis Elmer Potter
• C. Clarence Dally
• D. William H. Rollins

Answer: (D)

The question tests knowledge of who first championed safety in X-ray use for dentistry. William H. Rollins, a dentist from Boston, is celebrated as the Father of Radiation Protection because he was among the first to recognize the dangers of X-ray exposure and to push for concrete protective measures. He warned that repeated or prolonged exposure could cause tissue damage and cancer and argued for practical safeguards such as shielding between the patient and operator, keeping a safe distance from the source, and minimizing exposure time. He also supported improvements in technique and filtration to reduce dose. These enduring ideas laid the groundwork for modern radiation protection practices. Other pioneers contributed in different ways—Gustav Bucky and Hollis Elmer Potter are known for advancing image quality with grids, not for leading protection efforts, while Clarence Dally’s notoriety comes from suffering early X-ray injuries.
