X-ray research is a branch of science and technology that focuses on the use of X-rays for various applications, such as medical imaging, materials analysis, and non-destructive testing. X-rays are a form of electromagnetic radiation that can penetrate solids and produce images of internal structures by detecting variations in the absorption of X-rays by different materials. X-ray research involves studying the properties of X-rays, developing new X-ray imaging techniques, and exploring the potential applications of X-rays in various fields.
