X-Ray Radiography
← X-Ray Sources | ● | Attenuation Coefficient →
When X-raying an object or body, the electromagnetic waves are attenuated while traveling though the body on a straight line. The attenuation is caused by scattering and absorption effects. With good approximation, the attenutation is proportional to the density (resp. weight) of the X-rayed material.
The following physical processes are involved:
- Elastic scattering
- Photoelectrical effect
- Compton Scattering
- Pairing
