More Information
Increasing the energy of the incident beam usually leads to decreased attenuation in tissue due to higher penetration. Radiographic rating charts are commonly used to determine the safe operation of X-ray machines. Tesla is the S.I unit for magnetic field strength.
Tips
A common mistake is assuming that increased beam energy increases attenuation; however, higher energy means greater penetration and lesser attenuation.
