in this study, natural and artificial radioactivity concentration in agaricus bispora (nourished mushroom) and their composts, cantharellus cibarius and coprinus micaceuc (wild species) were determined. samples were collected from sahne and two kinds of wild mushroom species from songhor koliai township gardens all located in kermanshah province were collected. hpge gamma ray spectrometry syste...

Two measurement systems, one being comprised of three HPGe detectors and the other being a 4π measurement system of the assembly of 10 sets of scintillation detectors, were compared for their measurement performance in operations of radioactive waste drum radioactivity measurement and clearance and release operation of decommissioning. The system features of the former were high costs, capable ...
