A radiation detection apparatus can include a scintillator to emit scintillating light in response to absorbing radiation; a photosensor to generate an electronic pulse in response to receiving the scintillating light; an analyzer to determine a characteristic of the radiation; and a housing that contains the scintillator, the photosensor, and the analyzer, wherein the radiation detection apparatus to is configured to allow functionality be changed without removing the analyzer from the housing. The radiation detection apparatus can be more compact and more rugged as compared to radiation detection apparatuses that include a photomultiplier tube.

An X-ray detector comprises a first scintillator layer, a second scintillator layer, a first photodiode array, a second photodiode array, and at least one light emitting layer. The first scintillator layer is configured to absorb X-rays from an X-ray pulse and emit light. The first photodiode array is positioned adjacent to the first scintillator layer and is configured to detect at least some of the light emitted by the first scintillator layer. The second scintillator layer is configured to absorb X-rays from the X-ray pulse and emit light. The second photodiode array is positioned adjacent to the second scintillator layer and is configured to detect at least some of the light emitted by the second scintillator layer. The at least one light emitting layer is configured to emit radiation such that at least some of the emitted radiation irradiates the first photodiode array, and at least some of the emitted radiation irradiates the second photodiode array.

The present disclosure provides an image sensor and electronic equipment. The image sensor includes: a pixel array, comprising a plurality of pixels, wherein a light-transmitting part is disposed between adjacent pixels; a protective layer, covering at least a part of a surface of the pixel; a conversion layer, configured to convert X-ray into visible light; wherein when X-ray is incident from a side of the image sensor, a portion of the X-ray is incident on the protective layer, another portion of X-ray transmits through the light-transmitting part between the pixels, reaches the conversion layer, and is converted into visible light by the conversion layer and received by the pixel. With the above solution, the pixels can be protected from the damage of X-ray high-energy photons while improving the resolution of the captured X-ray image.

A device for the detection of gamma rays used primarily in a PET scanner is based on a scintillator heterostructure combining the high stopping power of scintillators commonly used in PET scanners (such as L(Y)SO, BGO, etc.) and very fast scintillators based on polymers loaded with fast emitting dyes or nanocrystals, or thin layers of nanocrystals or multiple quantum well structures. The particular arrangement of this detector module allows combining all the important features of a high-performance Time-of-Flight PET (TOFPET) detector module, i.e., a high photoelectric detection efficiency for the gamma rays, a precise 3D information (including the depth of interaction DOI) of the gamma ray conversion in the module, and good energy resolution.

A scintillator panel including a substrate, a barrier rib formed on the substrate, and a scintillator layer having a phosphor and sectioned by the barrier rib, wherein the barrier rib contains one or more compounds (P) selected from the group consisting of polyimides, polyamides, polyamideimides, and polybenzoxazoles.

A subsurface continuous radioisotope environmental monitor that provides a continuous monitoring of the possible presence of radioactive species in subsurface groundwater. The detector and all supporting system elements are specifically constructed and equipped to be permanently mounted in a well or borehole to continuously detect and record radiation decay of radioactive species that are borne by subsurface water flow to that sampling area. The system operates by placing a detection element in a housing such that subsurface water that reaches the bore or well can flow in contact with the detection element. The system can employ several detection modes and materials. The detector includes SiPMs operating in a coincidence spectroscopy configuration to significantly reduce spurious signals due to thermal noise as well as increasing the total amount of signals collected.
