Internal lead shielding for clinical electron treatments. [PDF]
J Appl Clin Med PhysAbstract Electron beams are often used to treat superficial lesions of the lip, cheek, nose, and ear. Lead is frequently used to block distal structures. It is customary to place an internal bolus of low atomic number in between the tissue and the lead to reduce electron backscatter from the lead.
