More Information
In radiology, depth dose calculations are important for ensuring proper dosage in treatments. For electron beams, the depth of penetration is generally shallower than for photon beams.
Tips
Avoid assuming the reference depth dose for X-rays is more than a few millimeters as it is generally shallow.
