Abstract: Monte Carlo computer simulation of beta radiation transport within radioactively-contaminated food samples was studied and compared with experimental results. We used the Monte Carlo code PENELOPE-2008. The basic geometry of a hand-held contamination monitor and the geometry of beta-emitting food samples and surface sources were modeled, and the detection efficiency of the device was determined. Possibilities to improve the detection efficiency were tested by simulation. [ABSTRACT FROM AUTHOR]
