摘要： Un dispositivo detector de multiples fotones de fondo ultrabajo para radioisotopos (20) tiene un fondo de aproximadamente un conteo por día y puede detectar un "attomol" (quintillonésima parte de mol) de material. Dos detectores de fotones de rayos gama y X opuestos incluyen cada uno preferiblemente un cristal de escintilacion (22) y un tubo fotomultiplicador (26). Entre los detectores están emparedados un separador (32) y un sujetador de muestra (34) para una muestra (36) marcada con un radioisotopo tal como I125. Cada detector convierte emisiones de radioisotopo en impulsos de salida eléctricos en una base (30) cuyos impulsos se someten luego a procesamiento de señales para análisis de forma de impulsos, discriminacion de eventos coincidentes de los no coincidentes y cuantificacion del radioisotopo. Los materiales detectores y componentes se seleccionan para reducir al mínimo el fondo y son protegidos de radiacion externa en una proteccion mixta (55). Se pueden usar detectores que operan en diferentes principios y sujetadores de muestra de diferentes configuraciones. El dispositivo además se puede construir para resolver y proveer imágenes de disposiciones de muestra de dos dimensiones.

摘要： A scintillation crystal and a method for producing same are provided for a radiation detector. According to a first embodiment the crystal comprises a first layer (22; 22') of a crystal material having relatively poor mechanical properties and a high energy resolution, and a second layer (24; 24') of a crystal material having relatively good mechanical and optical properties. Both layers are arranged on top of each other. Preferably a third layer (26) is provided, and the first layer (22. 22') is arranged in sandwich form between the second and third layer. In a second embodiment, a scintillation layer (22) is evaporated on an elastic intermediate layer (18: 29b) which is provided on a substrate (18; 29b). In a third embodiment, a substrate (29c) having an uneven or grooved surface (60) is provided, and a scintillation layer (22c) is evaporated on said surface (60). In a fourth embodiment, a freely supported scintillation layer (22d) is applied. This layer (22d) is sandwiched between two protective layers (24, 26) one of which is coupled to a glass plate (18) via an elastic light coupling medium (27).

摘要： The use of divalent fluoride dopants in scintillator materials comprising cerium fluoride is disclosed. The preferred divalent fluoride dopants are calcium fluoride, strontium fluoride, and barium fluoride. The preferred amount of divalent fluoride dopant is less than about 2 % by weight of the total scintillator. Cerium fluoride scintillator crystals grown with the addition of a divalent fluoride have exhibited better transmissions and higher light outputs that crystals grown without the addition of such dopants. These scintillators are useful in radiation detection and monitoring applications and are particularly well suited for high rate applications such as positron emission tomography (PET).

摘要： A scintillation measurement system for measuring optical events produced by scintillators (19) in response to the radioactive decay of a constituent or constituents of a sample (10) to be measured comprises a sample support for positioning a sample in a sample well (11); a bismuth germanate (BGO) scintillation crystal (19), such as Bi4Ge3O12, located adjacent the sample well; a plurality of photodetectors (16, 18) located outside the bismuth germanate crystal (19) for detecting optical events occuring in the sample well (11) or in the bismuth germanate crystal (19) and converting those optical events into electrical pulses; and a pulse analyzing system (40) for receiving the electrical pulses from the photodetectors and determining whether such pulses represent alpha, beta or gamma events. This system can be used with samples containing alpha, beta or gamma emitters, or any combination thereof.

摘要： The compound scintillation detector (1) with high space and time resolution with scintillation elements (8a - 8e) are created by single crystals of ytrite-aluminium garnet both with ingredient of cerium with polished surface. The input surfaces (9a - 9e) and the bases (10a - 10e) for input of scintillation radiation are created on the opposite ends of scintillation elements (8a - 8e). The level of reflection of dielectric reflecting layers for a light emitted by scintillation elements (8a to 8e), incidenced on the reflecting layers under the angle of incidence within a range 0 to 45 DEG is higher than 50 %. The reflecting layers are created by a deposition and followed chemical-thermal processing. The bases (10a - 10e) for input of scintillation light have anti-reflecting layers on which a light is incidenced under the angle within the range for 0 to 45 DEG . The input surfaces (9a - 9e) of scintillation elements (8a - 8e) are advantageously created by dielectric interference or diffusion reflecting layer with a thickness up to 5 mu m. The effective optical separation of particular scintillation elements (8a - 8e) is advantageously realized by light-tight layer created by metal deposition. The considerably compact variant of the detector (1) is reached by a filler. The optical evaluation equipment (4) connected with the basis (10a - 10e) is created by photomultiplier with high space resolution.

摘要： A unitized scintillation detector (500), employing a scintillation element (514) and a photomultiplier tube (16) housed within inner and outer housings for protection against shock, and a scintillation shock assembly. The scintillation element (514) is encased within potting material, which is enclosed within a rigid shield (30). The element (514) is further protected from shock by an elastomeric boot disposed around the shield (30) and within the housing. Elastomeric material cushions the element (514) on one end and a spring system protects the other end. The spring system is pre-loaded against the shield (30), not the element (514). Dual windows (622) interfacing the scintillation element (514) and photomultiplier tube (16) at the other end of the element (514) create an hermetic seal. The photomultiplier tube (16) is encased within an elastomer with outwardly directed projections. The photomultiplier tube (16) is protected from radial and axial shock as well as thermal excursions. The optical window (622) is hermetically sealed through the use of a thin braze ring (708).

摘要： A neutrino detection method is described and comprises the stages of exposing a detector to a neutrino flux, said detector comprising an assembly of fluorindate monocristals, identifying the number of events corresponding to the capture of high energy neutrinos by fluorine atoms, deducing therefrom the number of high energy neutrinos striking the detector, identifying the number of events corresponding to the capture of high energy neutrinos by indium atoms, deducing therefrom the activation cross section of the indium for the high energy neutrinos, and using this activation cross section value to calibrate reactions resulting from interaction of low energy neutrinos and indium.
