摘要： A nuclear radiation detection system for remote monitoring of movement of nuclear material over a road or highway. Nuclear fiber sensors, which may be several meters long, are covertly positioned in at least two monitoring points, such as buried shallowly under the roadway or hung from a tunnel wall, along the path which a nuclear source may be clandestinely moved. These fiber sensors are individually connected, by an epoxy glue, to individual transmitting optical fibers. Movement of a nuclear radiation source in close proximity to the fiber sensors at the two or more monitoring points produces an optical signal which exceeds a preestablished threshold. These optical signals travel through the transmitting optical fibers, which may be about 1 kilometers long, to a electronic system comprised of a microprocessor controlled signal detecting, signal processing and even data storage means. The optical fibers and electronic system are also selectively hidden from view for security reasons. Any movement of a nuclear source is detected by strength and duration radiation signal data which is stored in the microprocessor memory. This data may be removed from the processor and read out by a data key means.

摘要： A radiation detection system for use in the visible and near infrared reg which is capable of detecting and recording extremely weak laser pulses in the few nanoseconds range. The system receiver can be directed towards strong radiation sources, such as the sun, without changing the receiver or recording unwanted information. The detection system discriminates between various selected laser sources wavelengths and is comprised of optics, detector, electronic hardware, microcomputer, and signature analysis algorithm.
