wheat is a staple food in pakistan. production of wheat is increased with extensive use of phosphate based fertilizers in agricultural fields. activity mass concentration of primordial radionuclides due to use of phosphate fertilizers in soil enhances the external gamma dose and due to the consumption of wheat food grown on these soils also increases the internal dose. different types of soil, ...

The detection and identification of radiation sources at distances in the range of 15 meters or more is becoming increasingly important for illicit materials interdiction and the location of lost or orphan sources. In most locations, there is a considerable gamma-ray flux from natural background (NORM) and cosmic-induced nuclides. This gamma-ray flux varies with time, weather conditions, locati...

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...

In this paper we describe the development, testing, and characterization of three low-emission rate AmLi neutron sources. The sources are used to calibrate nuclear recoil response LUX-ZEPLIN (LZ) dark matter experiment. sources' emission was measured using $^{3}$He proportional tubes. gamma emissions were characterized a high-purity germanium (HPGe) detector. Source-validated GEANT4 Monte Carlo...

The Pd nucleus has been studied with the Mo(B, p2nγ) reaction at 43 MeV incident energy. γ−γ− t, γ−γ− charged particle coincidences and directional correlation ratios were measured using the γ spectrometer formed by four Compton suppressed HPGe detectors and a 4π charged-particle ancillary detector system. The struture of the bands was interpreted within the framework of the cranked shell model...
