Neutron Measurements Using the Universal Radiation Spectrum Analyzer

摘要

The Universal Radiation Spectrum Analyzer (URSA-Ⅱ), developed by Radiation Safety Associates, and manufactured by SE International (Figure 1) is an interface between a radiation detector and a personal computer. Originally, the URSA-Ⅱ was developed for use with detectors that measure the energy of gamma rays. At the Idaho National Laboratory, the URSA-Ⅱ is an integral part of standard measurement techniques to measure characteristics of neutron radiation fields. Those techniques are discussed briefly and spectra using the URSA-Ⅱ are presented.
