    Abstract

    Several new cross section libraries, such as ENDF/B-VI (revision 2), IRDF-90, JEF-2.2, and JENDL Dosimetry, have recently been made available to the dosimetry community. The Sandia National Laboratories (SNL) Radiation Metrology Laboratory (RML) has worked with these libraries since pre-release versions were available. This paper summarizes the results of the intercomparison and testing of dosimetry cross sections. As a result of this analysis, a compendium of the best dosimetry cross sections was assembled from the available libraries for use within the SNL RML. This library, referred to as the SNLRML, contains 66 general dosimetry sensors and 3 special dosimeters unique to the RML sensor inventory. The SNLRML cross sections have been put into a format compatible with commonly used neutron spectrum determination codes.
