摘要: A radiation sensor device may include at least one radiation sensor configured to capture radiation measurement data, a location circuit to determine physical location data, a clock to provide timestamp data, and one or more communication interfaces configured to communicate with a radiation mapping system through one or more of a communication network or a communications link. The device may include a processor configured to selectively control a frequency of operation of the one or more sensors to capture the radiation measurement data based on changes to the physical location data. The device may be configured to correlate the radiation measurement data to the physical location data and the timestamp and to determine an anomalous radiation measurement based on the radiation measurement data relative to background radiation data. The device may send an alert to the radiation mapping system in response to determining the anomalous radiation measurement.

摘要: A method of measuring a radon concentration or a radon exposure level comprising: placing a plurality of individual radon measurement instruments at locations, each instrument being capable of data output; receiving radon measurement data from each of said plurality of instruments; combining said data from said plurality of instruments into a single data set; and calculating a radon concentration or radon exposure value from said single data set. Using a plurality of individual detectors and combining their data provides a much better overall analysis of radon concentration or radon exposure level. The calculated value may include producing an average of the radon concentrations across the multiple instruments. The average may be weighted with weights determined according to different locations such as proximity to ventilation devices or based on the time that an average user spends in each location.

摘要: A large-area directional radiation detection system may include a large number of slab-shaped detectors stacked side-by-side comprising alternate long and short detectors, where the long detectors are longitudinally longer than the short detectors. The long detectors may collimate or restrict the lateral field of view of the short detectors, so that a particular short detector that is aligned with the source has an unobstructed view of the source. By comparing detection distributions in the long and short detectors, a processor can determine the angular position and distance of a source. The high detection efficiency and large solid angle of the detector array may enable rapid detection of even well-shielded threat sources at substantial distances, while simultaneously determining the positions of any sources detected.

摘要: Calibration devices including germanium-68 source material are disclosed. The source material may be a matrix material (e.g., zeolite) in which germanium-68 is isomorphously substituted for central atoms in tetrahedra within the matrix material. Methods for preparing such calibration devices are also disclosed.

摘要: Methods and systems are disclosed for the deployment and operation of shipping container scanning systems that enables scanning of containers passing through a modern, highly automated port without impeding the flow of commerce. Locating the scanners where container dwell time is already longest, and configuring scanners to scan up to several containers in parallel but under separate scanning control, minimizes any delay associated with scanning. Operationally integrating scanning systems with the automated logistical port systems ensures smooth, delay-free operation. Controlling the flow of information so that scanning results, including but not limited to images and assessments of the presence or absence of threat material or contraband, are sent only to government Customs and/or security facilities adjacent to but separate from the port insulates port operators from involvement in activities that could slow container throughput.

摘要: A multi-radiation identification and dosimetry system and method that allows for monitoring of alpha, beta, and gamma radiation is disclosed. The system/method incorporates a segmented silicon drift detector (SSDD) that allows measurement of directly absorbed radiation in the semiconductor (betas, conversion electrons, Lx lines, and alphas) on one SSDD segment and radiation from a radiation scintillation detector (RSD) on multiple segments of the SSDD. With the anode side of the SSDD directed toward the radiation inspection surface (RIS), the SSDD+RSD stacked radiation detector collects radiation which is processed by a charge sensitive amplifier (CSA) and then processed by a time stamping differentiator (TSD). A computing control device (CCD) may be configured to collect the time stamp differentiation data from the various SSDD segments to permit the simultaneous discrimination of several types of radiation by and presentation of these radiation types and counts on a display monitor.

摘要: A management method of a lubricating oil of the invention is a method of managing a lubricating oil by determining a degradation degree of the lubricating oil containing an antioxidant, specifically, according to determination methods a and b below. The determination method a includes: measuring an infrared ray absorption spectrum of the lubricating oil using a Fourier transform infrared spectrometer; and calculating a total content of the antioxidant and an altered substance having an antioxidant function to determine a deterioration degree of the lubricating oil from the obtained content. The determination method b includes: filtrating the lubricating oil with a filter; subsequently measuring a color difference of substances captured by the filter using a colorimeter, or measuring a color difference of the lubricating oil using the colorimeter; and determining a degradation degree of the lubricating oil and a mixture degree of foreign substances based on the obtained color difference.
