Compositionally Disordered Ceramic (Gd,Y,Tb,Ce)3Al2Ga3O12 Phosphor for an Effective Conversion of Isotopes’ Ionizing Radiation to Light

“…Table 2 demonstrates that activities and energy deposits from the isotopes suitable for αand β-irradiation conversion are comparable with the irradiation conditions used. The profiles of the energy losses in (Gd,Y,Tb,Ce) 3 Al 2 Ga 3 O 12 material for 5.5 MeV α-particles and β-particles having a spectrum of 147 Pm [58] are shown in Figure 9.…”

“…Table 2 demonstrates that activities and energy deposits from the isotopes suitable for α-and βirradiation conversion are comparable with the irradiation conditions used. The profiles of the energy losses in (Gd,Y,Tb,Ce)3Al2Ga3O12 material for 5.5 MeV αparticles and β-particles having a spectrum of 147 Pm [58] are shown in Figure 9. When using a converter with an area of 1 cm 2 and a density of 6 g/cm 3 , α-particles with an energy of 5.5 MeV are absorbed with an average range of approximately 17 μm (90% of the energy deposition), and the mass of the layer subjected to the radiation damage is 10 −5 kg.…”

Study of the Nuclear Structure for Some Target Nuclei Used in the Production of Beta-Emitting Radioactive Isotopes for the Fabrication of Nuclear Batteries

“…Nuclear batteries convert thermal energy resulting from the decay of radioactive material into .electricity [1,2]. There are two main types of nuclear batteries, which are the thermal converting and non-thermal converting such as betavoltaics [3]. This type of batteries converts energy disintegration into electricity via p-n junctions using semiconductor devices, because of the greater densities of energy and the longer radioisotope life relative to the other types [4].…”

High-Performance Polymer Type Capacitors

“…For comparison, 3,6-di(4′-trifluoromethylphenyl) pyromellitic dianhydride (6FPMDA) and 3,6-diphenyl pyromellitic dianhydride (DPPMDA) were utilized The prepared polyimides exhibited high Tg (276-314 °C), excellent thermal stability (>500 °C in air), good adhesive property (104.7-126.3 g/mm), good solubility, and very low dielectric constant (2.34-2.89). Kavetskiy et al [43] calculated beta particle surface fluxes for tritium, Ni-63, Pm-147, and Sr-90 sources. The high current density was experimentally achieved from Pm-147 oxide in the silica-titana glass.…”
