title: Characterization of a p(66)Be(49) neutron therapy beam II: skin-sparing and dose transition effects.
abstract: Results of buildup measurements in A-150 tissue equivalent plastic are presented for a p(66)Be(49) neutron beam. These measurements were taken in air and behind various materials to answer questions about skin-sparing, bolussing materials, recovery of skin-sparing, and dosimetry in small radiobiological samples. The depth for Dmax for this beam is 1.6 g cm-2. An algorithm is also presented that reproduces the measured dose buildup curves.
