A radiograph is an image produced on a photosensitive surface or digital sensor by the passage of X-rays through an object. It is commonly used in medical settings to visualize the internal structures of the body, such as bones and organs. The varying absorption of X-rays by different tissues creates a contrast that allows healthcare professionals to diagnose conditions. In addition to medicine, radiographs are also used in fields like dentistry and industrial testing. In dentistry, they help identify cavities and assess tooth health. In industry, radiographs can detect flaws in materials, ensuring safety and quality in products.
