Finding unequivocal evidence of dark matter interactions in a particle detector is major goal research physics. Liquid argon time projection chambers offer path to probe Weakly Interacting Massive Particles scattering cross sections on nuclei down the so-called neutrino floor, mass range from few GeV hundreds TeV. Based successful operation DarkSide-50 at LNGS, new and more sensitive experiment...

A virtual counter was developed to count the signals from a scintillation detector. After were processed by some electronic devices, they counted and real counter. The counts obtained both counters accumulated via different amplifier gains source-to-detector distances investigate their effects on recorded counts. results compared with those of one. It concluded that could be used radiation dete...

gamma camera is an important apparatus in nuclear medicine imaging. its detection part is consists of a scintillation detector with aheavy collimator. substitution of semiconductor detectors instead of scintillator in these cameras has been effectively studied. in this study, it is aimed to introduce a new design of p-n semiconductor detector array for nuclear medicine imaging. a p-n semiconduc...

Abstract Detectors for direct dark matter search using noble gases in the liquid phase as a detection medium need to be coupled liquefaction, purification and recirculation systems. A dedicated cryogenic system has been assembled operated at INFN-Naples laboratory with aim liquefy purify argon used an active target detectors study scintillation ionization signals detected by large SiPM arrays. ...

The half-life of 87Rb was measured by a liquid scintillation method according to the efficiency tracing method. The measuring sample of rubidium chloride was dissolved in a scintillation cocktail of Insta-gel, and the rubidium was determined by gravimetry as tetraphenylborate. The result was (5.56 +/- 0.025) x 10(10) years.

A new radioanalytical method was developed for rapid determination of (226)Ra in human urine samples. The method is based on organic removal and decolourisation of a urine sample by a polymeric (acrylic ester) solid phase sorbent material followed by extraction and preconcentration of (226)Ra in an organic solvent using a dispersive liquid-liquid microextraction technique. Radiometric measureme...

Nuclear products which were caused by the D + D nuclear fusion reaction were searched in electrolytic cells and in gas phase of Pd + D systems. Measurements of nuclear products were made for gamma-ray, neutron, tritium and helium. To detect neutron, liquid scintillation and He counters were used. For gamma-ray measurement, a NaI detector was used. For tritium concentration measurement in gas ph...

The indoor 222Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing -3 dm3 of ambient air through 16 ml of water-immiscible non-volataile scintillation cocktail Ultima-Gold F for 10 min. The activity of radon and its two α-emitting daughters: 218Po and 214Po, was determined with the BetaScout low-background liquid scintillation counter. The limit of 222Rn d...
