According to the design need of the shielding of therapy head in the 14MeV neutron therapy system of Lanzhou University
this paper simulated the transfer process of neutron at a source to body surface distance of 100cm by Monte Carlo method (mcnp3b). The dose transmissivity of fast neutron on the complex shielding of various combination was calculated. Optimum scheme of shielding was designed. It supplied a scientific basis for the design of therapy head.
