We report on a study of the performance DEGAS-FATIMA Hybrid setup through GEANT4 simulations using accurate geometries all detector components. give details most compact configuration considered for this when maximizing efficiencies both DEGAS (HpGe) and FATIMA (LaBr3(Ce)) systems with respect to heavy-ion implantation β-decay station. The possible configurations system are discussed in terms t...

This work aims to determine natural radionuclides (210Pb, 228,226Ra, 234,228Th and 40K) in NORM samples by well-type HPGe detectors because they are of vital importance studies on environmental samples. For this, a novel methodology has been developed, based obtaining general function for the full-energy peak efficiency (FEPE) versus sample apparent density composition, keeping height constant....

Abstract In this study, the effect of various types fertilizers on natural radioactivity levels in agricultural soil was investigated research. The activity concentration 226Ra, 232Th, and 40K fertilizer samples were determined by using gamma-ray spectroscopy a high-purity germanium (HPGe) detector to determine concentrations 40K. for phosphate raw (2300-5400) Bq/kg, (9-53) (56-3000) respective...

Measurement of 238U, 233Th and 40K concentrations in soil samples collected from Ziggurat Dur-Kurigalzu west region Baghdad, have been evaluated, using high purity germanium detector. The activity varied 16.040 to 26.620 , 14.510 31.480 153.820 266.320 with average values 20.604±2.9 24.534±3.3 212.22±25.1 respectively. importance these measurements lies the estimation radiation risk, radium equ...
