摘要：
This paper describes the performance of a 1.5 in. x 1.5 in. LaBr3 gamma radiation detector for determining U-235 enrichment by non-destructive analysis. The spectrometric properties of the detector, brought to market under the trade name BrillanCe-380 [1], were first evaluated. Enrichment measurements were subsequently carried out in different experimental conditions on certified uranium samples with enrichment ranging from 0.31% to 60% and on UF6 containers of the type 30B and 48Y.
