Some metals continuously emit energy due to their unstable atomic nuclei. This flowing energy is called radiation, and these substances are known as radioactive materials. Radioactivity was discovered by a scientist named Henri Becquerel. Later, scientists like Rutherford and Madame Curie conducted further research. For his discovery, Becquerel was awarded the Nobel Prize in Physics in 1903.

Henri Becquerel was born on December 15, 1852, in Paris. His father and grandfather were also scientists. After completing his secondary education at the local Lycée Louis-le-Grand, he joined the École Polytechnique. In 1892, he was appointed to a significant position at the National Museum of Natural History. He began his career as an engineer in government bridge and road construction. In 1896, through experiments on various metals including uranium salts, he discovered radioactivity and gained fame. He also discovered that uranium is a metal that continuously emits radiation. In 1903, he was awarded the Nobel Prize jointly with Pierre and Marie Curie. In addition to the Nobel, Becquerel received many honors for his contribution to science, such as the Rumford Medal, the Helmholtz Medal, and the Barnard Medal. He passed away on August 25, 1908. It is said that his premature death was caused by the adverse effects of radioactivity on his body during his experiments.
