dc.description.abstractThe absorption and scattering of neutrons by neutron optical elements, beam stops and other components present significant radiation shielding challenges due to the generation of gamma radiation. In the case of neutron absorbers incorporating lithium- 6, fast neutrons are also generated. We show how Monte Carlo simulations using the MCNP computer code may be used to model the radiation fields produced by such components, thereby assisting in the choice of materials for shutters and other elements and assisting in the design of shielding. We discuss the use of these techniques to model instrument shielding bunkers, comprised principally of lead walls with boron-containing linings, for diffractometers at the OPAL Reactor, ANSTO. © 2005 The Authorsen_AU
