Abstract:
As a wide band-gap and direct transition semiconductor material, ZnO has good scintillation performance and strong radiation resistance, but it also has a serious self-absorption phenomenon that affects its light output. After being doped with Ga, it can be used for the scintillator of ultra-fast scintillating detectors to detect X-ray, gamma, neutron, and charged particles with extremely fast response and high light output. Firstly, the basic properties, defects, and scintillation mechanism of ZnO crystals are introduced. Thereafter, magnetron sputtering, one of the most attractive production methods for producing ZnO:Ga film, is introduced including the principle of magnetron sputtering and its technical parameters’ influence on the performance of ZnO:Ga. Finally, ZnO:Ga film’s application research status is presented as a scintillation material in the field of radiation detection, and it is concluded that some problems need to be urgently solved for its wider application.

Abstract:
Abstract The selection of suitable high-efficiency scintillation detectors plays an essential role in improving the quality of PET images. Many studies have used two layers of crystal detectors with different scintillation materials. This research uses GATE simulation to simulate an animal PET system with a two-layer detector. By varying the type of the crystal detectors, essential parameters such as sensitivity, scatter fraction, noise equivalent counting rate, spatial resolution, energy resolution, and time resolution for different scintillation materials were calculated and compared to determine the most efficient solutions. This simulation used scintillating materials; LYSO, GSO, LSO, BGO, YAP, LuAP, and LPS in 12 different states. Results showed that by increasing the distance of the source from the center in the radial direction, the two-layer crystals with different scintillation materials have a better radial spatial resolution than the same material of crystals. As a general result, the PET system's performance, designed from two-layer crystals with different scintillation materials, lower layer LuAP and upper layer BGO or same-material of BGO, is more desirable than the rest.

Abstract:
AbstractBhat et al. (1998) presented a model in which they explain the increase in scintillation bandwidth with decreasing pulsar distance as being due to a shell of scattering material associated with the Local Bubble. However, Britton et al. (1998) concluded that the scattering material for local pulsars is nearer to the pulsar (i.e. possibly in a bow shock or shell near the pulsar). We have investigated the effects of the local bubble shell and pulsar bow shocks on the scintillation bandwidth, the scintillation timescales and the angular broadening of pulsars. We find that a) there is no evidence for a shell of scattering material associated with the Local Bubble because the scintillation timescale data do not fit the Bhat et al. model and the angular broadening measurements do not suggest a scattering screen near the Sun, and b) that pulsar bow shocks cannot produce any enhanced scintillations.

Abstract:
An important background to the liquid argon detectors is that they are caused by the diffusion of radioactive isotopes in a scintillator (liquid phase). This radioactive isotope is produced in argon’s surrounding devices, such as circulation pipelines and liquid argon containers. The solid argon as a scintillation material in the detector can inhibit the diffusion and drift of radioactive isotopes in a solid phase scintillator. Additionally, the structure of a solid argon detector is simple and reduces the total source of radioactive background. In the CDEX-300 detection system, solid argon could substitute for liquid argon as the veto detector, preventing radioactive isotopes drifting to the central main detector (HPGe detectors array) surface to reduce backgrounds. Therefore, solid argon has great potential in the experiments since it is especially helpful to get the lower background in a larger active volume than liquid argon required in those low background detection experiments. This work introduces the preparation process and device of the large volume transparent crystalline argon, the acquisition of scintillation light, and the pulse amplitude spectrum of 137Cs obtained from a prototype detector of transparent solid argon crystal. The results show that the scheme proposed in this study can successfully produce a large volume transparent crystalline argon detector, the scintillation light signals can be effectively obtained from the solid argon scintillator, and the corresponding pulse amplitude spectrum is given. This work indicates that it is feasible to develop a solid argon crystal scintillation detector by using our approach.

Abstract:
A semiconductor scintillation-type gamma radiation detector is discussed in which the gamma-ray absorbing semiconductor body is impregnated with multiple small direct-gap semiconductor inclusions of bandgap slightly narrower than that of the body. If the typical distance between them is smaller than the diffusion length of carriers in the body material, the photo-generated electrons and holes will recombine inside the impregnations and produce scintillating radiation to which the wide-gap body is essentially transparent. In this way it is possible to implement a semiconductor scintillator of linear dimensions exceeding 10 cm.

Abstract:
Nowadays, radioactive materials are being applied in medical imaging. Because humans cannot observe radiation, radiation detection materials are very important to humans. A scintillator is a material that can change gamma photons to visible photons. Good scintillators should have the following properties: high scintillation light yield, good energy resolution, and high density. In this work, the scintillation light yield property of CWO crystals was studied due to its interesting properties, such as high stopping power and low hygroscopicity. CWO crystals were compared with BGO crystals. From the results, it was found that the BGO crystals showed higher scintillation light yield value at 662 keV energy from 137Cs radioactive source than the CWO crystals, resulting in better energy resolution value. The intrinsic light yield and loss parameters for both crystals are also presented in this work.

Abstract:
Ceramics from cerium-doped quintuple garnet-type compounds (Gd,Y,Lu)3Al2Ga3O12:Ce with different contents of Y and Lu have been fabricated and studied as a prospective scintillating material enabling improvement of scintillation properties by tuning of the composition of the matrix-forming crystalline compound. The coprecipitation method was applied to produce powders of complex garnet compounds, which were subsequently compacted and sintered. The influence of the matrix composition on photoluminescence and scintillation of the ceramics is studied using luminescence spectroscopy at steady state and pulsed excitation. Partial substitution of Lu by Y ions was found to be an effective tool for tailoring of scintillation properties of the material. A light yield of the Gd2Y0.5Lu0.5Al2Ga3O12 composition was measured to be 41 000 ph/MeV, whereas a scintillation kinetics was measured to have dominant fast scintillation components: 14 ns (84%) and 78 ns (16%).

Full text
Abstract:
Scintillator materials convert high-energy radiation into photons in the ultraviolet to visible light region for radiation detection. In this review, advances in X-ray emission dynamics of inorganic scintillators are presented, including inorganic halides (alkali-metal halides, alkaline-earth halides, rare-earth halides, oxy-halides, rare-earth oxyorthosilicates, halide perovskites), oxides (binary oxides, complex oxides, post-transition metal oxides), sulfides, rare-earth doped scintillators, and organic-inorganic hybrid scintillators. The origin of scintillation is strongly correlated to the host material and dopants. Current models are presented describing the scintillation decay lifetime of inorganic materials, with the emphasis on the short-lived scintillation decay component. The whole charge generation and the de-excitation process are analyzed in general, and an essential role of the decay kinetics is the de-excitation process. We highlighted three decay mechanisms in cross luminescence emission, exitonic emission, and dopant-activated emission, respectively. Factors regulating the origin of different luminescence centers controlling the decay process are discussed.

Abstract:
The water-based liquid scintillator (WbLS) is a new material currently under development. It is based on the idea of dissolving the organic scintillator in water using special surfactants. This material strives to achieve the novel detection techniques by combining the Cerenkov rings and scintillation light, as well as the total cost reduction compared to pure liquid scintillator (LS). The independent light yield measurement analysis for the light yield measurements using three different proton beam energies (210 MeV, 475 MeV, and 2000 MeV) for water, two different WbLS formulations (0.4% and 0.99%), and pure LS conducted at Brookhaven National Laboratory, USA, is presented. The results show that a goal of ~100 optical photons/MeV, indicated by the simulation to be an optimal light yield for observing both the Cerenkov ring and the scintillation light from the proton decay in a large water detector, has been achieved.

Abstract:
L'ion ytterbium trivalent présente la particularité de pouvoir donner lieu à deux émissions aux propriétés spectroscopiques différentes : l'une, de durée de vie courte, dans l'ultraviolet (émission de transfert de charge) employée au sein de détecteurs tels que les scintillateurs, et l'autre, de durée de vie longue, dans l'infrarouge (émission de type 4f x 4f) pour des applications de type laser.La relation étroite qui existe entre structure et propriétés de la matière est illustrée au travers de l'étude de la luminescence de l'ytterbium, dans l'ultraviolet et l'infrarouge, inséré dans le borate Li6Y(BO3)3 ainsi que deux oxyborates : LiY6O5(BO3)3 et Y17,33B8O38. Pour la première fois dans des oxyborates une émission de transfert de charge de l'ytterbium a été observée. Une approche théorique a permis le calcul des courbes à une seule coordonnée de configuration des niveaux d'énergie de la liaison ytterbium - oxygène, ainsi que la simulation de l'extinction thermique de cette émission. L'étude de la spectroscopie infrarouge de l'ytterbium dans ces composés a été réalisée et une attribution des niveaux d'énergie est proposée dans le cas du borate Li6Y(BO3)3 : Yb3+. Une approche originale est également introduite avec l'étude des états de transfert de charge pour les trois composés via l'émission dans l¤infrarouge. Les premiers tests portant sur les performances lasers dans trois régimes de fonctionnement (continu, déclenché et blocage de modes) d¤un cristal de Li6Y(BO3)3 : Yb3+ (Yb-LYB) sont reportés.

Full text
Abstract:
This research explores the synthesis of anthracene and stilbene-based metal-organic framework (MOF) structures as potential scintillating (radioluminescent) materials for use in the detection of gamma radiation. The organic molecules 9,10-anthracenedicarboxylic acid (ADCH2) and trans-4,4’-stilbenedicarboxylic acid (SDCH2), were each used as a linker, in combination with a range of lanthanide metal ions, to synthesize novel three dimensional MOF structures under hydrothermal conditions. With ADCH2, the early period lanthanides yield isostructures with the metal ion in higher coordination (nine) than for those with late period metals (seven). The ADC-MOFs show linker-based photoluminescence properties with well defined vibronic peaks in their emission profile and their emission (λmax~435 nm) blue shifting from that of the ADCH2 powder (~500 nm) and closer to the organic molecule in monomer arrangement (λmax ~ 420 nm). The structures also show photoluminescence lifetimes between 1 and 2 ns, which is similar to the reported value for monomeric anthracene units. The blue-shift and reduction in lifetime, compared to ADCH2, are indicative of minimal π-π interactions amongst the aromatic moieties, thereby limiting the non-radiative relaxation pathways. On exposure to ionizing radiation (protons and g- rays), the ADC-MOFs demonstrated scintillation properties, with a radioluminescence lifetime of ~ 6 ns which is similar to that of the ADCH2 powder. A combination of SDCH2 and lanthanide metal ions produced two isostructured MOFs containing Tm3+ and Er3+, under the hydrothermal synthesis conditions explored. The 3-D structure contained ultra large diamond-shaped pores with dimensions of 16 Å x 30 Å. A blue-shift of fluorescence spectra was observed for the SDC-MOF structures (λmax ~ 425 nm) compared to that of bulk SDCH2 powder (λmax ~475 nm), and closely resembling that of monomeric isolated SDC units (λmax~475 nm). Their photoluminescence lifetime is ~0.76 ns, about half of that observed for SDCH2 powder. The blue shift and reduction in lifetime (compared to SDCH2) is attributed to minimal π-π interactions between SDC units in the MOF structure, thus minimizing associated non-radiative relaxation pathways. The isolation of anthracene and stilbene in MOF structures therefore has the potential to improve their performance as scintillators.

Neste trabalho avaliou-se o efeito da microestrutura na cintilação de nanopartículas de Y2O3:Eu3+. Neste contexto utilizam-se dois métodos de síntese, o método Pechini, que apresenta matéria orgânica remanescente de síntese, assim como, aglomerados micrométricos constituídos de partículas nanométricas com variação da forma e tamanho. Utilizando o método de precipitação homogênea modificado, estudou-se a influência de partículas com estreita distribuição de tamanho e morfologia esférica. A estrutura apresenta simetria cubica (grupo espacial Ia3) e com os estudos espectroscópicos caracterizou-se a presença de pelo menos dois sítios de simetria sendo eles C2 e S6. Avaliou-se o efeito da temperatura de tratamento térmico de 700 a 1100 ºC na cristalinidade do material através de difratometria de raios x do pó. Por meio da espectroscopia de luminescência com excitação de raios X, avaliou-se o efeito da microestrutura do material na cintilação.

In this work one consider the effects of microstructure in the scintillations properties of Y2O3:Eu3+. Two preparation methods were used; the Pechini method, which exhibits remaining organic matter derived from the synthesis, and tends to form agglomerates of nanoparticles with variable shape and size. By using a modified method of homogeneous precipitation one studied the effects of spherical particles with narrow distribution of particle size in its scintillation properties. The Y2O3 presents cubic symmetry (Ia3 space group) and with spectroscopy results at least two Y3+ symmetry sites were identified, a C2 and a S6 site. The firing temperature of the samples (700- 1100oC) was correlated with its crystallinity by X-ray diffractometry data. The relation between the integrated emission intensity of 5D0 ® 7F2 transition and the firing temperature or the Scherrer crystallite size were analyzed, and from these results were observed the influence of defects in the scintillation of particles, since in lower firing temperatures and/or lower crystallite sizes defects are presented in higher concentrations, leading to non-radiactive paths of pairs recombination. By using radiation damage measurements it was possible to identify the steps involved in the scintillation process, as the creation of defects, which presents a direct relation with the particles characteristics. After a long exposition time to the incoming ionizing radiation, the materials present constant scintillation intensity or a linear growth by means of recovery processes. Samples prepared by the homogeneous precipitation presented higher scintillation intensity and a higher recovery ability when fired at high temperatures.

Abstract:
AbstractFour simplified examples of actual safeguard calculations are provided. First is a combined (α,n) and spontaneous fission source in a nuclear fuel assembly in a water tank with fission detectors. Second is an HLNC2 high level neutron coincidence counter for spontaneous fission and (α,n) neutron multiplicity counting. Third is an NaI scintillation detector for a photon pulse-height tally measurement of a photon source from a cylindrical UO2 pellet. Fourth is a Cf shuffler, utilizing a 252Cf spontaneous fission source, used to measure a nuclear material item, with 3He tubes measuring the time-dependent delayed neutron buildup signature. The MCNP output from these calculations provides the data for safeguard analysis.

Full text
Abstract:
Abstract Fast neutron multiplicity counting (FNMC) analysis method, as a new non-destructive analysis method for nuclear materials, plays an increasingly important role in the measurement of nuclear material properties. Based on the derivation of the FNMC analytical equation of Pu material, the method of solving the sample parameters was given. By analyzing the mechanism of interaction of neutrons and matter, the model used by Geant4 (version 10.4) software was determined, and a set of three-layer, fast neutron multiplicity counters with six liquid scintillation detectors per layer was constructed. Using the fast neutron multiplicity counter to analyze the measured parameters, the detection efficiency variation was less than 0.4% within the 150g sample mass range, and the PuO2 fluctuation was less than the metal Pu. By studying the detection efficiency and the multiplicity counting rate as a function of sample mass, within the 150g sample mass range, both basically meet the model assumptions of the FNMC analytical equation. The metal Pu and PuO2 samples were set separately, and the FNMC analysis equation was solved. When the sample mass was within 150g, the sample mass solution deviation was less than 10%. The results show that the built-in fast neutron multiplicity counter can better measure Pu sample properties.

Full text
Abstract:
Tension metastable fluid states offer unique potential for radical transformation in radiation detection capabilities. States of tension metastability may be obtained in tailored resonant acoustic systems such as the acoustic tension metastable fluid detector (ATMFD) system or via centrifugal force based systems such as the centrifugal tension metastable fluid detector (CTMFD) system; both under development at Purdue University. Tension metastable fluid detector (TMFD) systems take advantage of the weakened intermolecular bonds of liquids in sub-vacuum states. Nuclear particles incident onto sufficiently tensioned fluids can nucleate critical size vapor bubbles which grow from nanoscales and are then possible to see, hear and record with unprecedented efficiency and capability [1]. Previous work by our group has shown the ability of TMFD systems to detect neutrons with energies spanning eight orders of magnitude with 95%+ intrinsic efficiency [2] while remaining insensitive to gamma photons and also giving directional information [3] on the source of the radiation. In this paper we describe research results with CTMFD systems for use in the detection of key actinide isotopes constituting special nuclear materials (SNMs) in spent fuel. Tests in a CTMFD system demonstrate the ability to detect alpha activity (at ∼100% efficiency) of U-isotopes at concentrations of ∼100 ppb (which is unprecedented and about x100–1000 more sensitive than from conventional liquid scintillation spectroscopy). An inherent capability of TMFD systems concerns on demand tailoring of fluid tension levels allowing for energy discrimination and spectroscopy. This appears especially useful to detect the key isotopes of U and other transuranic isotopes of Pu, Np, Am, and Cm that are at different stages of nuclear fuel reprocessing (i.e. UREX+).

Abstract:
Abstract A prompt gamma neutron activation analysis (PGNAA) system based on a deuterium-deuterium (D-D) sealed neutron generator was designed using the MOCA code for explosive detection. The system is mainly composed of four parts: D-D sealed neutron generator, moderator, shielding, and Lutetium Yttrium OxyorthoSilicate (LYSO) scintillation detectors. Polyethylene (PE) was selected as the moderator and the optimal thickness was 7cm. Lead, PE, and boron-containing polyethylene were used as shielding materials. In the optimized model, the LYSO detector is used to measure eighteen materials, such as wood, melamine, glucose, and nylon, and so on. Firstly, the nitrogen characteristic peak of 10.8 MeV was analyzed to determine whether the material contained nitrogen. Then, the ratio of characteristic peak counts of C/O and O/N were calculated to distinguish explosives from nitrogen containing materials. Finally, dinitrobenzene, nitroglycerin, TNT, and ammonium nitrate can be separated from nitrogenous substances by a discriminant algorithm. The final device can be used to detect the chemical composition of the threat substances, and the maximum dose rate of the system meets the limits of international protection standards.

Abstract:
During operation and maintenance, or decommissioning of nuclear power plant, various kind of waste should be treated, and exposure control is also required. These wastes have a wide range of contamination, different composition of nuclides, and a different shape, so each measurement instrument would be optimized for its use especially for very low level radioactivity measurement. TOSHIBA provides appropriate equipment for any needs to discriminate the very low and non radioactive waste to save cost of waste disposal, based on our original and innovative technology. For alpha emitting nuclides, we are ready to supply instruments based on ionized particle measurement technology. For beta, gamma-emitting nuclides, we are ready to customize a shape of detector based on our original plastic scintillation material. Some examples are introduced.
