AbstractAbstract
[en] The D2O-moderated 252Cf source at the NBS was developed as a calibration test source, whose spectrum simulates that found in the vicinity of light water reactors. The D2O/Cf-252 source is to be used for calibrating neutron personnel dosimeters and for LWR research. One of the requirements involved in the choice of a suitable reference source for this purpose is that a number of testing laboratories should be able to reproduce the source based on the NBS model. A source based upon the NBS prototype, consisting of a 30 cm diameter spherical stainless steel tank covered with a cadmium shell, has been fabricated for use at the University of Arkansas SEFOR Calibration Center. The Arkansas source differs from the NBS model in some small details, mainly concerning the method of loading the californium capsule into the central stem. Compatibility of measurement techniques is discussed, as well as the extent to which the desired reproducibility of the source spectrum has been ahieved
