NCRP Report No. 79, Neutron Contamination from Medical Electron Accelerators
NCRP Report No. 79 is concerned with the potential for neutron exposure that results from medical equipment used to generate electrons is operated at energies above 10 MeV. The Report reviews the source of neutrons generated from medical electron accelerators and provides an examination of the transport of the neutrons in the protective housing of the accelerator, as well as in structural shielding barriers. The Report also presents and outline of the hazards to operating personnel and patients, and treats the methods for reducing these hazards. The Report includes a description of methods of measuring neutrons from various types of medical accelerators, and includes factors for converting neutron fluence to dose and dose equivalent.
