X-ray Interaction with matter

-Attenuation; a reduction in the intensity of a beam of x-radiation as it passes through a medium due to absorption or to scatteringor to both. -Absorption; the transfer of energy from the x-ray beam to the medium through which it passes. -Scattering; a change in the direction of a photon due to interaction with the medium, this can occur with or without the loss of energy from the photon. -4 types of x-ray interaction withn …showed first 75 words of 873 total…

After a specific time the nucleus achieves stability by the emission of a gamma ray. Electron Capture; is another way in which an unstable nucleus can achieve stability. This process takes place in nuclei which have too many protons. The nucleus captures an electron from the k-shell which then combines with a proton to form a neutron.
