¿Qué es la RADIACIÓN? ☢

The video explores the nature of radiation, distinguishing between electromagnetic and nuclear types. It recounts the discovery of X-rays by Virgin Ronquen and the subsequent experiments by Harry Becquerel and Marie Curie, who contributed significantly to our understanding of radioactivity. The video explains the concept of ionizing radiation, its potential dangers, and its applications in medicine and technology. It also discusses everyday exposure to radiation and emphasizes the importance of understanding radiation to mitigate fear.
