X-rays are a form of electromagnetic radiation that can penetrate various materials, including human tissue. They are widely used in medicine for diagnostic purposes, allowing healthcare professionals to view the internal structures of the body without invasive procedures. X-rays help in identifying fractures, infections, and tumors, making them an essential tool in modern healthcare. The process of taking an X-ray involves directing a controlled amount of radiation towards the body, which is then captured on a film or digital sensor. The resulting images provide valuable insights into a patient's health, aiding in timely and accurate diagnoses. Safety measures are in place to minimize exposure to radiation, ensuring that the benefits of X-ray imaging outweigh any potential risks.
