• Atmospheric Radioactivity Definition: Fallout (specifically radioactive fallout) is the airborne residual radioactive material propelled into the upper atmosphere and stratosphere following a nuclear explosion, which subsequently settles back to the earth's surface.
• Biological Hazards: Radioactive fallout contains dangerous radionuclides including Strontium-90 ($^{90}\text{Sr}$, bone-seeker), Iodine-131 ($^{131}\text{I}$, thyroid-seeker), and Caesium-137 ($^{137}\text{Cs}$), which enter human and animal food chains through pasture contamination and milk consumption.

Correct option: (4) Fall out
