In 1896, French physicist Henri Becquerel accidentally discovered spontaneous radiation. He was studying uranium salts to see if sunlight would trigger them to emit rays like X-rays. His experiment involved placing the salts on a photographic plate wrapped in black paper and exposing them to sunlight. When cloudy weather forced him to pause, he stored the materials in a dark drawer. Later, upon developing the plate, he found a clear image of the uranium crystals, showing that they emitted powerf
