Which hazard is associated with radiography?

• A. None of these
• B. Hearing loss
• C. Burns or scalds
• D. Cancer

Answer: (D)

Ionizing radiation used in diagnostic radiography can damage DNA. Over time, this DNA damage can lead to mutations that increase the risk of cancer in exposed tissues or individuals, especially with repeated or higher-dose exposures. That connection—radiation exposure raising cancer risk—is why cancer is the primary hazard associated with radiography.

Hearing loss isn’t a typical risk from standard radiography, and burns or scalds would more likely involve other situations or improper exposure, not routine imaging. The key idea is to minimize exposure as much as possible: use shielding, proper collimation, correct technique to avoid retakes, and keep exposure time and dose as low as reasonably achievable. In practice, protective gear and dosimeters help manage cumulative risk for staff, while safe practices protect patients.
