X-Rays _ GCSE Physics

X-rays, part of the electromagnetic spectrum, have a small wavelength allowing them to penetrate tissues but are absorbed by dense materials like bones. They are used in medical imaging, such as diagnosing fractures and CT scans, which provide detailed 3D images. X-rays are ionizing radiation, posing risks like DNA damage and cancer, but can also treat cancer in radiotherapy. Radiographers follow safety protocols to minimize exposure. Interestingly, a flight from London to New York exposes you to more radiation than an X-ray.
