摘要：

The neutron and photon fields present at the Fast Neutron Beam of RPI were simulated with MCNP-4C and measured with activation foils, TLDs and ionisation chambers. In general, there is a good agreement between calculations and measurements, although the model overestimates the thermal neutron component. Aluminum oxide TLDs were found to be promising for monitoring the photon dose in actual irradiations of circuits.
