The present invention relates to a .sup.10B enriched plastic scintillators, methods of making the same and methods of using the same. Neither carboranes nor .sup.3He are required to be included in the plastic scintillators, which can be used in neutron detection.

A DR detector includes a housing enclosing a two-dimensional array of imaging sensors and a radiopaque battery in the form of a sheet configured to provide electrical power to the imaging sensors and to shield against undesired radiographic radiation. The radiopaque battery layer covers an area about the same as, or a major fraction of, a front or back surface of the DR detector.

The present invention is directed to systems and methods for producing an improved PSD scintillator by including a cross-linking agent, such as BPA-DM, in the polymer from which the scintillator is machined, and to PSD scintillators produced thereby. The cross-linking agent could also be used for plastic scintillators with significant incorporation of specialized dopants (boron, lead or bismuth) for thermal neutron or gamma radiation detection.

The present disclosure relates to a method for detecting incoming radiation having a plurality of differing properties including at least one of differing types, differing energies or differing incoming directions. The method involves using a scintillator structure formed from first and second dissimilar scintillator materials, where the first and second dissimilar scintillator materials emit first and second different colors of light in response to the incoming radiation. A first light detector is used for detecting light having the first color, and a second light detector is used for detecting light having the second color. A first output signal is generated in response to the detection of light having the first color, and a second output signal is generated in response to detecting light having the second color. The first and second output signals are then analyzed to determine at least one property of the incoming radiation.

Polymerization composition for manufacturing a hybrid material for plastic scintillation detection comprising: a) monomers, oligomers or their mixtures intended to form at least one constituent polymer of a polymeric matrix and b) a liquid fluorescent mixture comprising i) 95.6 molar % to 99.1 molar % of a main primary fluorophore consisting of naphthalene and ii) 0.9 molar % to 4.4 molar % of an additional primary fluorophore; wherein the centroid of the light absorption spectrum and of the fluorescence emission spectrum, the fluorescence decay constant and the fluorescence quantum yield of which are judiciously chosen. The decay constant of the fluorescence of the hybrid material manufactured with the polymerization composition is intermediate between that of a fast plastic scintillator material and of a slow plastic scintillator. Further, it can be chosen over a wide range. The invention also relates to ready-for-use kits for manufacturing a polymerization composition.

A scintillator material includes a polymer matrix, a primary dye in the polymer matrix, the primary dye being a fluorescent dye; a secondary dye, and a Li-containing compound in the polymer matrix, where the Li-containing compound is a Li salt of a short-chain aliphatic acid. In addition, the scintillator material exhibits an optical response signature for thermal neutrons that is different than an optical response signature for fast neutrons.

A radiation detector may include an active structure having an input face and an output face for incident ionizing radiation. The active structure may include: a first organic scintillator including at least one neutron-absorbing material and enabling discrimination between fast neutrons, thermal neutrons, and photons; at least one second scintillator arranged in front of the first scintillator and capable of preferentially detecting the alpha and/or beta radiation, the two scintillators having, due to the choice of their constituents, different mean pulse decay constants, and the second scintillator having a thickness smaller than the first.

An object of the present invention is to enable a scintillator panel of a type having a barrier rib to have sufficient mechanical strength and enhanced brightness. 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.

Provided are a scintillator with improved energy sensitivity dependence within the energy range of diagnostic X-rays, more specifically in the range of 40-150 kV, and a radiation dosimeter using same. Due to the scintillator comprising a photopolymer resin that contains a polymerizable monomer, a filler, and a photopolymerization initiator, energy sensitivity dependence within the range of 40-150 kV is improved. Furthermore, changes in relative sensitivity within this energy range can be reduced to 3% or less by containing an inorganic fluorescent substance such as Zn.sub.2SiO.sub.4.

The fastener system can include a first fastening member extending through the compression member and into the component and a second fastening member within the component and coupled to the first fastening member. The apparatus can include a pliable moisture barrier that separates an inner region from an outer region. The component and the second fastening member can be within the inner region, and the first fastening member can be within the inner region and within the outer region.
