Detection of internally deposited actinides. Part IV. Preliminary considerations in the use of large, planar intrinsic Ge detectors

PDF Version Also Available for Download.

Description

Many inherent advantages are apparent in the use of large planar Ge detectors for the detection, identification, and quantitative assessment of internally deposited actinide nuclides ($sup 238$Pu, $sup 239$Pu, $sup 240$Pu, $sup 242$Pu, $sup 241$Am, $sup 244$Cm, $sup 246$Cm, and $sup 250$Cf). The superior energy resolution in contrast to Phoswich type scintillation detectors, permits isotopic identifications to be made and reduces ambiguities introduced by natural and human background effects. Preliminary studies indicate that a 10 cm$sup 2$ x 1.2 cm Ge detector is comparable in detection sensitivity to that of one 125 cm$sup 2$ Phoswich detector. Some preliminary considerations and ... continued below

Some preliminary considerations and evaluations, photon transport studies based on Monte Carlo modeling and measurements of absolute L-series X-ray yields in the decay of several actinide nuclides, are presented.
