In the year 1910, a groundbreaking scientific experiment was conducted by physicist Henri Becquerel, who discovered radioactivity. This phenomenon, characterized by the spontaneous emission of particles or radiation from unstable atomic nuclei, intrigued the scientific community. Following his discovery, scientists like Marie Curie expanded on Becquerel's findings, demonstrating that certain elements, such as uranium and radium, emit high levels of radiation without external influence. The implications of this discovery were profound, impacting fields ranging from medicine to astronomy, as researchers began to explore the application of radioactive materials in various industries. Over the ensuing decades, the understanding of radioactivity led to both significant advancements, including cancer treatments and energy production, as well as concerns regarding safety and environmental effects.
