WebOct 10, 2024 · Photoelectric effect. An x-ray photon interacts with a bound electron from the inner shell. All of the energy of the photon is transferred to the electron. The electron then has enough energy to be freed as a photoelectron and leaves a ‘hole’ in the shell. The hole is filled by electrons from outer shells.

X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. churches and tax id

"WebFor conventional radiography, an x-ray beam is generated and passed through a patient to a piece of film or a radiation detector, producing an image. Different soft tissues attenuate x-ray photons differently, depending on tissue density; the denser the tissue, the whiter (more radiopaque) the image. " - Ray tissues

WebX-ray absorption (or attenuation) allows us to use X-Rays to produce images. The dark and light areas on a radiograph image represent the intensity of X-Rays that reach the detector plate. They indicate the level of attenuation caused by the tissues between the source and detector. Because different tissues attenuate X-rays by different amounts ...
