A radiation detector is provided. The radiation detector includes an outer casing, at least one first detector disposed within said outer casing, the at least one first detector configured to primarily detect gamma ray radiation, at least one second detector disposed within the outer casing, the at least one second detector configured to primarily detect neutron radiation, and a computing device disposed within the outer casing and communicatively coupled to the at least one first detector and the at least one second detector. The computing device is configured to receive first data from the at least one first detector, receive second data from the at least one second detector, determine a number of neutrons and gamma rays detected based on the first and second data, and determine a detected energy spectrum based on the first and second data.

The present disclosure is directed to liquid boron compounds for use in scintillation. The present disclosure further relates to liquid boron compounds for admixture to plastic and liquid scintillators.

A dual mode radiation detector can include a compact casing, a scintillator; and a photosensor disposed on the scintillator. The scintillator can be the only detection medium disposed within the casing. The radiation detector can have a Pulse Shape Discrimination Figure of Merit of at least 1.5, or a neutron detection efficiency of at least 0.06 cps/ng .sup.252Cf, measured at 1 meter with a 5 cm high density polyethylene moderator, each measured at a temperature of 22° C.

Scintillator materials, as well as related systems, and methods of detection using the same, are described herein. The scintillator material composition may comprise a Tl-based scintillator material. For example, the composition may comprise a thallium-based halide. Such materials have been shown to have particularly attractive scintillation properties and may be used in a variety of applications for detection radiation.

A neutron scintillator is formed of a resin-based composite. The resin-based composite includes a phosphor part (A) formed of a resin composition including inorganic phosphor particles containing at least one kind of neutron-capturing isotope that is selected from lithium 6 and boron 10 such as Eu:LiCaAlF.sub.6 and a resin, and at least one wavelength converting part (B) comprising a wavelength converting fiber or a wavelength converting sheet. In the neutron scintillator, it is preferred that the wavelength converting part (B) is enclosed in the phosphor part (A).

The invention concerns a scintillation detector with which high count rates and/or high resolutions are possible. The scintillator of the claimed scintillation detector is formed from pixels (2), which are separated from each other by interstices (4). Alternatively or additionally, the surface of the scintillator is divided by grooves into pixels (2). Such a structure enables not only a particularly high resolution. When multiple detector modules are used, it also allows high count rates in the range of roughly 20 MHz.
