A new generation of high-resolution hypernuclear γ-spectroscopy experiments with high-purity germanium detectors (HPGe) are presently designed at the FINUDA spectrometer at DAΦNE, the Frascati φ-factory, and at PANDA , the pp hadron spectrometer at the future FAIR facility. Both, the FINUDA and PANDA spectrometers are built around the target region covering a large solid angle. To maximise the ...

Pure tungsten (W), irradiated to 3.5 dpa in a target of the Swiss neutron spallation source (SINQ), was characterized using high-sensitivity HPGe gamma ray spectroscopy identify present radionuclides. Synchrotron X-ray absorption used quantify amount Re produced W. An atomic concentration 0.61% W determined from height L3-edge edge jump. Analysis local structure extended fine (EXAFS) spectra in...

Diatomite (diatomaceous earth) and clay minerals deposits from the mining basin Kolubara, Serbia, are natural materials with high economic potential in many fields. As received treated materials, diatomite were characterized using X-ray diffraction, mercury intrusion porosimetry, particle size distribution, scanning electron microscopy, Fourier-transform infrared spectroscopy. Activity concentr...

Radioactivity was measured for 170 cow's milk samples in Salah-Din governorate. Samples were by a gamma spectrometry system, using high purity germanium (HPGe) detector. The detector shielded 10 cm all sides with cadmium copper the inner sides. selected characteristic peaks detection of different ware 1460kev K-40. energy calibration performed set standard ray sources Eu-152. results show prese...

Measurements with a bare p-type high purity germanium diode (HPGe) submerged in a 19 kg liquid argon (LAr) scintillation detector at MPIK-Heidelberg are reported. The liquid argon–germanium system (LArGe) is operated as a 4π anti-Compton spectrometer to suppress backgrounds in the HPGe. This R&D is carried out in the framework of the Gerda experiment which searches for 0νββ decays with HPGe det...

The cross section of the 12 C(α,γ) 16 O reaction, well-recognized as most important nuclear input stellar evolution theory, has eluded precise measurements over last few decades, evident in lack confirmation an elementary prediction quantum mechanics E1-E2 mixing phase angle (ϕ ). More troubling are modern data, measured with 4π array HPGe detectors, that conflict this prediction. A new method ...

The Laboratorio Subterráneo de Canfranc (LSC) is the Spanish national hub for low radioactivity techniques and associated scientific technological applications. concentration of airborne radon a major component radioactive budget in neighborhood detectors. LSC hosts Radon Abatement System, which delivers suppressed air with 1.1±0.2 mBq/m3 222Rn. content continuously monitored an Electrostatic M...

The accident at the Fukushima Daiichi Nuclear Power Plant resulted in a substantial release of radionuclides into the environment. Consequently, the emergency operation workers were exposed to both external gamma and beta radiations arising from the fallout; however, their beta doses were scarcely recorded at the time due to an insufficient number of dosemeters. To solve this problem, the autho...

background: some particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. the radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. the result of gamma spectrometry measurement of the concentrations of the na...
