Abstract: A neutron measuring method is provided. The method includes utilizing the thermoluminescent crystal in the thermoluminescent dosimeter to convert the ionizing radiation emitted by an activated metallic body into scintillation light. The method further includes using a photodetector to measure the intensity of the scintillation light. The method further includes calculating the activity of the metallic body based on the intensity of the scintillation light and the second conversion factor. The method further includes using the second conversion formula to calculate the neutron intensity at the location of the metallic body based on the calculated activity of the metallic body.

Abstract: Systems and methods for detecting radiation are generally described. The radiation detector comprises at least one semiconductor material, such as a thallium halide, that provides an electrical signal and optical signal upon exposure to a source of radiation. The electrical signal and optical signal may both be measured to detect the radiation.

Abstract: A device for measuring water content of the ground, vegetation and snow includes an ambient neutron detector to measure ambient neutron flow, having first and second sheets made at least partially with a scintillator. A light meter measures light conveyed by a light guide interposed between the first and second sheets. The ambient neutron detector transforms interaction with particle(s) into an electric charge. A programmable control unit connects to the ambient neutron detector, and includes an integrating circuit transforming the electric charge produced by interaction with the particle(s) into a signal. The control unit processes the signal to discriminate a signal generated by ambient neutron, incident cosmic rays and/or background noise, and measures ambient neutron flow, incident cosmic rays, and/or background noise. The measurement of the water content is obtained from measurement of normalized ambient neutron flow with respect to measurement of cosmic rays flow incident to the ground.

Abstract: An apparatus to detect neutrons and gamma rays is provided. The apparatus has at least one scintillator material and at least one neutron-gamma converter in gamma communication with the scintillator material. The neutron-gamma converter is adapted to emit gamma radiation upon capturing neutrons. The apparatus further has an analyzer. The neutron-gamma converter has at least one isotope having a daughter nucleus having a level scheme having at least one long-lived excited state, where the long-lived excited state has a lifetime between 1 nanosecond and 500 nanoseconds, and is at least sometimes involved in de-excitation cascades following neutron captures. The analyzer finds and analyzes delayed detections comprising prompt components and delayed components in the recorded signal in order to quantify event parameters and to compute a measure for a thermal neutron flux the apparatus is exposed to using the event parameters.

Abstract: A sensor board comprising a substrate comprising a pixel region where pixels are arranged on a first surface of two surfaces, a scintillator arranged on one of the first surface and a second surface of the two surfaces and a light shielding member arranged on the surface on which the scintillator is arranged, is provided. The pixel region comprises a first region where a signal for radiation image is generated and a second region where a signal for correcting a signal output from the first region is generated. The scintillator is arranged to overlap the first region but not to overlap the second region. The light shielding member is arranged to cover the scintillator and overlap the second region. A portion of the light shielding member overlapping the second region is bonded to the surface on which the scintillator is arranged.

Abstract: A radiation detector and detection method comprising one or more antineutrino capture sections having a plurality of cells. The cells including hydrogen, act as scintillators and contain a wavelength shifter. Also included are a plurality of neutron capture layers containing a neutron capture agent. The cells are disposed between said neutron capture layers. The layers act as scintillators to convert the radiation emission of a neutron capture to light for transmission to at least one of the cells and the cells and layers have different scintillation time constants.

Abstract: Boron nitride nanotubes (BNNTs) with 10B combined with a scintillation gas can serve as the basis for detecting thermal neutrons by detecting light from the decay products of the thermal neutron's absorption on the 10B atoms in the BNNT Material as the resultant decay products pass through the scintillating gas. BN-NTs with 11B can be utilized as a scaffold for 238U and combined with a scintillation gas as the basis for detecting fast neutrons via detecting light from the fission decay products passing through the scintillating gas. Both technologies provide high spatial and temporal resolution for the detection of thermal neutrons and fast neutrons respectively.
