After a nuclear explosion, heat and light are produced making what?

• A. Ultraviolet exposure
• B. Electromagnetic pulse
• C. Thermal Radiation
• D. Nuclear radiation

Answer: (C)

Heat and light from a nuclear blast show up as thermal radiation. This radiant energy comes from the incredibly hot fireball and surrounding atmosphere, arriving as visible light and infrared heat very quickly. It can cause flash burns and ignite materials at significant distances. The other effects—electromagnetic pulse and nuclear radiation—are separate phenomena: EMP mainly disrupts electronics, while nuclear radiation refers to ionizing particles and photons that cause exposure over time, not the immediate heat and light. Ultraviolet exposure is another form of radiation, but the intense heat and bright flash from the explosion are best described by thermal radiation.
