    Abstract: A nuclear level sensing gauge for measuring the level of product in a bin utilizes a plurality of scintillators arranged in a serial fashion. A source of nuclear radiation is positioned adjacent the bin, and the scintillators, which may be bundles of one or more scintillating fibers or scintillating crystals, are positioned in a serial fashion adjacent the bin opposite the source of nuclear radiation, such that nuclear radiation passing through the bin impinges upon the bundles. Light guides carry photons emitted by the scintillators—which are indicative of radiation passing through the bin—to a common photomultiplier tube. The tube is connected to electronics which convert counts of photons from the PMT into a measure of the level of radiation-absorbing product in the bin.

    Abstract: A method of detecting and/or analyzing a radioactive source emitting charged or neutral particles in a biological tissue, consisting essentially in using scintillating fibers having particular ratios of length or diameter to range of the particles emitted by the source; scanning the surface of the material with the detection rod; collecting by means of a SiPM, the scintillation light output generated by the particles having interacted with the scintillating fibers and emitted at the outlet end; optionally selecting signals corresponding to the particles entering the scintillating fibers in a substantially axial direction, that eliminates the particles from certain angles between the axis of the scintillating fiber and the direction of the particles entering the scintillating fiber, correlating the scintillation light output and the selected signals to the presence of a source of radiation located in the material to be analyzed; and optionally communicating these data to the user.

    Abstract: A radiation detection device, system, and method for use in homeland security is disclosed. The device is portable and includes a photomultiplier tube (PMT) connected to an end of a substantially rigid thin-walled aluminum tube. Inside the aluminum tube, a substantially straight scintillating fiber is disposed (so as to be shielded from ambient light), and an end of the scintillating fiber is optically coupled to the PMT. A voltage output signal from the PMT is signal-processed with a filter to remove high-frequency noise (which may arise from solar radiation spikes) and fed to a voltage-responsive alarm or signalling device. The portable device is employed, for example, by responders to nuclear incidents and is packaged as a small wearable hands-free and eyes-free unit with a continuous in-use self-testing feature.

    Abstract: A portable nuclear material detector generally includes a scintillating fiber radiation sensor, a light detector, a conditioning circuit, a frequency shift keying (FSK) circuit, a fast Fourier transform (FFT) circuit, an electronic controller, an amplitude spectral addition circuit, and an output device. A high voltage direct current (HVDC) source is provided to excite the light detector, while a separate power supply may be provided to power the remaining components. Portability is facilitated by locating the components of the detector within a handheld-sized housing. When bombarded by gamma particles, the radiation sensor emits light, which is detected by the light detector and converted into electrical signals. These electrical signals are then conditioned and converted to spectral lines. The frequency of a give spectral line is associated with a particular radioactive isotope, while the cumulative amplitude of all spectral lines having a common frequency is indicative of the strength and location of the isotope. All or part of this information (identity, strength, direction, and distance) may be provided on the output device.
