title: [Characteristics of the RBE of a therapeutic beam of fast neutrons from a U-120 cyclotron].
abstract: RBE of a therapeutic neutron beam obtained at the U-120 Cyclotron by a 9 Be(d, n)10B reaction (13.6 MeV deuterons) was determined. X-radiation of 180 kW was used as a standard. As estimated by the test of 30-day death of rats subjected to whole-body irradiation, RBE of fast neutrons varied from 3.44 to 2.03 within the dose range from 0.4 to 2.7 Gy. As estimated by the growth inhibition (during 60 days) of Guerin's carcinoma inoculated in rat femur RBE varied from 4.68 to 2.76 within the dose range from 2.3 to 12.0 Gy.
