摘要： A radiation detector head assembly is provided that includes a detector housing, a detector unit, and a fastener. The detector housing defines a cavity therein, and includes a shielding body disposed at least partially around the cavity. The detector unit is disposed within the cavity, and includes an absorption member and associated processing circuitry. The processing circuitry is configured to generate electronic signals responsive to radiation received by the absorption member. The fastener extends through the detector housing, and is accepted by the detector unit to secure the detector unit to the detector housing. The shielding body of the detector housing is interposed between the fastener and the processing circuitry.

摘要： Embodiments relate to a method and apparatus for detecting radioactive and nuclear materials. Embodiments are directed to a method and apparatus for detecting neutrons and gamma rays. Embodiments relate to a low cost, scintillating material composition using an organo-metal scintillating material and Gd that can form a large area detector of neutrons and gamma rays with good discrimination between the two forms of radiation. Embodiments of a detector incorporating such a scintillating material can act as a passive detector to detect RDD and lightly to moderately shielded SNM or a detector used with active interrogation to detect RDD and to detect lightly, moderately, and heavily shielded nuclear material. Embodiments are used for detecting radiological and nuclear threats where a single material composition is used for both the neutron and gamma ray detection in the detector system. The nuisance alarm rate during detection of RDD is very low and allows a high flow of commerce. Operation of the detection system is unaffected by severe changes of the environment and assures both short term and long term stability and low life cycle costs.
