Which of the following is NOT a type of burn?

Radiation burns are indeed a recognized type of burn, specifically resulting from exposure to certain types of radiation, such as ultraviolet (UV) radiation from the sun or from radiation therapy in a medical setting. The classification of burns generally includes thermal burns caused by heat, electrical burns from electrical currents, chemical burns from corrosive substances, and radiation burns from exposure to radioactive materials or energy.

Thus, identifying radiation burns as a type of burn is accurate, as they can significantly impact tissue and require appropriate medical intervention. In this context, the focus on thermal, electrical, and chemical burns highlights the distinctions in the mechanisms that cause damage to the skin and underlying tissues.
