PbF2 compared to Al2O3 and AlF3 to produce an epithermal neutron beam for radiotherapy.

An evaluation of moderating materials is presented for boron neutron captured therapy. PbF{sub 2} was considered and its performance was compared to that of Al{sub 2}O{sub 3} and AlF{sub 3}. PbF{sub 2} is found quite effective as a moderator for medical epithermal neutron beams. (AIP) {copyright} {ital 1996 American Association of Physicists in Medicine.}
