摘要： A method and a system for detecting the presence of special nuclear materials in a container. The system and its method include irradiating the container with an energetic beam, so as to induce a fission in the special nuclear materials, detecting the gamma rays that are emitted from the fission products formed by the fission, to produce a detector signal, comparing the detector signal with a threshold value to form a comparison, and detecting the presence of the special nuclear materials using the comparison.

摘要： The present invention is directed to an integrated scintillator and collimator array for a CT detector. The integrated scintillator and collimator are fabricated from a manufacturing process or technique whereupon an array of scintillator material is positioned on a tooling base such that a collimator mold housing having a collimator mold therein may be positioned on the block of scintillator material. The block and mold housing are then aligned allowing a collimator mixture to be disposed into the mold. The collimator mixture is then allowed to cure to form an integrated scintillator and collimator.

摘要： A high-flow rate, low-noise, gas sampling apparatus for collecting particulate such as biological, chemical, and radioactive material from a gas on a collector such as an impaction collector includes a housing having an inlet and an outlet and a fan disposed within the housing for drawing the gas into the inlet, past the collector for sampling, and exhausting the gas through the outlet. The fan is operable to produce a flow of gas through the housing of greater than about 50 liters per minute with a noise level emitted from the apparatus being less than about 60 decibels. The apparatus may be configured as a compact, unobtrusive, portable, lightweight apparatus for use in various indoor or outdoor locations. The apparatus may also include a sensor for the detection of radioactive material collected on the collector, a processor for monitoring the sampling, and the apparatus may be linked to a communications network such as the Internet. Methods for collecting particulate from a gas are also enclosed.

摘要： The invention provides a technique for correcting gamma ray intensities detected to account for variation in attenuation effects with energy. The corrected intensity values enable more accurate isotopic analysis to be conducted and render such techniques applicable to low level emission cases. The technique is particularly useful in investigate waste materials with a gamma emitting content which needs to be determined. The attenuation is corrected for using a bi-modal function to account for the attenuation effects arising from low and high atomic mass components of the material in which the emitters are present.
