Review Questions

• How did Röntgen's discovery of X-rays in 1896 change medical practices?
  • Röntgen's discovery of X-rays in 1896 transformed medical practices by providing a non-invasive way to visualize the internal structures of the human body. This innovation allowed doctors to diagnose fractures and other conditions without the need for surgery, dramatically improving patient care. It marked the beginning of diagnostic radiology, which has become an essential part of modern medicine.
• What role did Henri Becquerel play in advancing our understanding of radioactivity in 1896?
  • Henri Becquerel made a significant contribution to our understanding of radioactivity in 1896 when he discovered that uranium salts emitted radiation without any external energy source. This observation laid the groundwork for further research into radioactive materials and led to the identification of other radioactive elements. His work prompted scientists like Marie Curie to investigate the properties and applications of radioactive substances.
