Which organs are primarily affected by infrared radiation?

• A. Eyes and Skin
• B. Liver and Kidneys
• C. Heart and Lungs
• D. Bones and Teeth

Answer: (A)

Infrared radiation mainly causes heating in tissue, so the organs that actually absorb and experience this energy are the skin and eyes. The skin is the outermost barrier and readily takes up IR energy, leading to thermal burns or erythema with exposure. The eyes are also highly vulnerable because the cornea and lens absorb infrared wavelengths, which can cause warming and potential eye injuries or cataracts with sufficient exposure. Internal organs like the liver, kidneys, heart, lungs, bones, and teeth aren’t the primary targets of infrared heating and would only be affected under extreme, widespread heat exposure or if the energy penetrated unusually deeply, which is not typical in standard IR hazards.
