In the frame of PANDORA project, a new experimental approach aims at measuring in-plasma β-decay rate as function thermodynamical conditions environment, namely laboratory magnetized plasma able to mimic some stellar-like conditions. The decay rates (expected change dramatically ionization state) will be measured charge state distribution ions. correlating environment and rate. This can perform...

In this research, polymers were fabricated through combining polyester, boron oxide (B2O3), and Tellurium (TeO2). B2O3 has good neutron absorption TeO2 is not only highly dense (5.670 g/cm3) but also environment-friendly, compared to PbO, as well being a photon absorber. The radiation protection features for five investigated samples examined utilizing an HPGe detector point sources Am-241, Cs-...

The radioactive isotope beam (RIB) of 25Na at 5MeV/u energy in maximum 3x107 pps intensity was fired on a deuterated polyethylene (CD2) to investigate mainly (d,p gamma) reaction. However, there were other reaction possibilities, which arisen from the same collision, be eliminated wisely. As particle detector and gamma-ray detector, highly selective double-sided silicon strip detectors (DSSSD) ...

Abstract Radiation and nuclear technologies have side effects in addition to their important applications, so appropriate shields must be used protect users the public from high doses as a result of exposure this radiation. In work, attenuation coefficients for polyester composites doped with waste iron filings (IFs) were studied. Six samples different IF concentrations manufactured, namely, Po...

Because the experimental efficiency calibration is limited to several measurement geometries and cannot be applied directly to all measurement configurations, the efficiency transfer method for the efficiency computation was applied using ETNA software. An approach using efficiencies measured with point sources combined with theoretical procedures was applied for obtaining the peak efficiency ε...

Nesse trabalho foi utilizada a técnica da espectrometria gama de alta resolução com detector HPGe e o pacote software GENIE 2000 para determinação concentração atividade dos radionuclídeos 226Ra, 232Th 40K presente em amostras solo, risco radiológico visitantes do Núcleo Piraquara, importante Trilha Ecoturismo Parque Estadual Pedra Branca – RJ. Os resultados apresentaram concentrações atividade...

abstract   background : the application of du emanation for first time contaminated certain areas in the south west region of iraq after the second gulf war (1991). these contaminated areas were discovered in 1994. radioactive contamination was detected using the nuclear enterprise pcm5/1 in soil samples collected from two regions near by grazing lands. this study was done for assessment of du ...

Abstract In this study, samples of building material additives were analyzed for naturally occurring radioisotope activity such as uranium, radium, and radon. The radon exhalation the annual effective doses, also calculated. activities samples, determined using HPGe gamma spectrometry ionization detector. results used to calculate dose values by RESRAD BUILD code. concentration ranges between 9...

Abstract $$\gamma $$ γ -ray tracking is based on a new generation of position sensitive high-purity germanium (HPGe) detectors. A novel type cluster detector was successfully developed and assembled for the high-resolution spectrometer Advanced Gamma Tracking Array AGATA. The core part consists three encapsul...

The Monte Carlo method is increasingly applied for simulation of germanium detectors. It can be successfully used for the evaluation of full energy peak efficiency or of the efficiency corrections due to self-attenuation, coincidence summing and geometry effects. Usually the simulation task is to evaluate the energy deposited in the sensitive volume of the detector, assuming that the detector s...
