Abstract

A spectroscopic radiation portal monitor (SPM) prototype consisting of four 10.16-cmtimes10.16-cmtimes40.64-cm sodium iodide (NaI) crystals has been constructed at Pacific Northwest National Laboratory (PNNL). The prototype was put through a variety of tests, including measurements of the absolute detection efficiency of unshielded sources and the detection efficiency and isotopic identification capability of the detector for shielded isotopic sources. The monitor´s response to various types of cargo and source configurations was also studied. The results of these tests are presented in this report
