Abstract
As use is made of a standard neutron field, formerly unidentified needs and ways to improve its performance became apparent. This paper presents improvements in calibration techniques, results of Monte Carlo calculations which better define scattering corrections, and new handling procedures which improve reproducibi1ity and decrease radiation exposure to personnel. Also, an application of the NBS 235U fission spectrum to test consistency among laboratories who analyze surveillance dosimetry for reactor pressure vessel exposures is summarized.
