    Abstract

    Sensitivities of neutron skyshine dose calculation from particle accelerators to certain parameters like roof thickness, distance of the neutron source from the roof, and fraction of the high-energy part of the neutron spectrum were evaluated using response surface methodology. The calculations were done for distances ranging from 100 to 2000 m for various nominal values of roof thickness and for 50- and 60-MeV α-induced neutron spectra on thick tantalum targets. Roof thickness is found to be the most sensitive parameter, and next is the high-energy part of the source neutron distribution, followed by the interaction term of the two variables.
