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...

a study on natural radioactivity in virgin and agricultural soil samples collected from sungai petani was conducted using high-purity germanium. the mean activity concentrations of 226ra, 232th, and 40k in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 bq kg−1, respectively. the co...

Abstract Experiments to search for neutrinoless double-beta (0 νββ ) decay of 76 Ge using a high-purity germanium (HPGe) detector rely heavily on background suppression technologies enhance their sensitivities. In this work, we proposed pulse-shape analysis method based neural network (NN) and light gradient boosting machine (lightGBM; LGB) discriminate single-electron (background) double-elect...
