...P. D. Ferguson; F. X. Gallmeier; L. K. Mansur; M. S. Wechsler A new method for the calculation of radiation damage parameters in large geometries encompassing multiple materials using the MCNPX mesh tally has been developed. The method has been tested against previously published calculations...
