In optical radiation hazards, exposure primarily causes which injury?

• A. Corneal burn
• B. RF burns
• C. Electrical shock
• D. Skin burns

Answer: (A)

The main risk from optical radiation hazards is to the eyes, because the cornea is the first tissue that absorbs UV, visible, and infrared energy. When exposed, the corneal surface can become damaged, leading to a corneal burn (photokeratitis). This is a common and immediate injury, often painful with tearing, blinking, and sensitivity to light, developing hours after exposure. While higher or prolonged exposure can affect deeper structures, the eye injury is the typical and most expected outcome of optical radiation exposure. Skin burns and electrical/ RF injuries are associated with different forms of energy and aren’t the primary concern with optical radiation hazards.
