The method and device to ensure the safety of people's life and health is based on the measurements of spontaneous electromagnetic radiation caused by the deformation from a structure or device, the nucleation and growth of plant cells and living organisms; calculating energy stored in a portion of the structure or cells based on the measured intensity; performing a comparison of the energy stored with a critical value for the structure and pathological changes in the cells; and indicate potential failure of the structure or the level of pathological changes based on the performed comparison.

The present specification discloses a multi-view X-ray inspection system having, in one of several embodiments, a three-view configuration with three X-ray sources. Each X-ray source rotates and is configured to emit a rotating X-ray pencil beam and at least two detector arrays, where each detector array has multiple non-pixellated detectors such that at least a portion of the non-pixellated detectors are oriented toward both the two X-ray sources.

An apparatus and method are provided for detecting indeterminate objects of interest contained within an encompassing medium using radiation event counts. Statistical analysis of measured events, such as local gamma radiation counts, is used to determine the probability of an object's presence in a field area. Event-detecting nodes are used to establish the baseline event activity such as background radiation (including environmental factors) in the field area, at a location determined unlikely to contain objects of interest due to geologic context or previous digging. Each node then independently detects and quantifies event activity, in an area to be evaluated, to derive evidence of the probability that an object of interest is within the medium. The calculated probabilities are then used to guide exploratory digging by indicating the likely direction and depth of an object of interest relative to the apparatus.

A method for characterizing a radiation source by a radiation portal monitoring system is described, the radiation portal monitoring system including a plurality of detectors including radiation detectors configured to detect ionizing radiation of the radiation source and to generate a detection signal responsive to detection of the ionizing radiation, and a control system including at least one processor executing the steps of: assigning an identification address to each detector; selecting a set of at least two detectors using the identification addresses; assigning an effective portal area to the selected set of detectors; receiving via a communication network a detection signal generated by the detectors of the selected set, using the identification addresses of the detectors of the selected set; and characterizing the radiation source associated with the effective portal area using the detection signal of the detectors of the selected set.

This invention is an apparatus for the detection of indeterminate objects of interest contained within an encompassing medium using event detection including but not limited to radiation event counts. Methods currently in use for this purpose rely on prior knowledge of the object's characteristics (size, age, orientation, etc.), as in the case of detecting possible nuclear devices being transported by a vehicle. Additionally, these methods rely on the use of heavy lead shielding to eliminate the effects of background and atmospheric radiation, which makes the apparatus difficult to move and limits the size of the measurable area. Such methods are highly impractical for use in field studies, where the specific characteristics of objects of interest are often unknown and difficult terrain makes the use of heavy, unwieldy equipment impossible.

This apparatus eliminates the need for both a complete understanding of an object's characteristics and the use of heavy shielding by relying on statistical analysis of measured events such as local gamma radiation counts to determine the probability of an object's presence. A plurality of independent event detecting nodes is first used to establish the baseline event activity such as background radiation (including environmental factors) in the field area, at a location determined unlikely to contain objects of interest due to geologic context or previous digging. Once the baseline radiation is established, the apparatus can then be moved to locations more likely to contain objects of interest. Each node then independently detects and quantifies the profile of event activity to derive evidence, when compared to the baseline, of the probability that an object of interest is within the medium. The calculated probabilities are then used to guide exploratory digging by indicating the likely direction and depth of an object of interest relative to the apparatus. By differentially measuring event activity such as background radiation with a plurality of event detecting nodes that can aggregate and groom results and incorporate them into the statistical analysis for in a specific area of interest, the need for event shielding techniques such as using heavy lead shielding is eliminated, making the resulting apparatus light and portable for easy use in the field. Additionally, it is unnecessary to know the specific characteristics of an object of interest, as the detected fluctuations of events such as gamma radiation are only meant to indicate the probability that any object is present within the medium. The versatility of the apparatus due to its size, multi-sensory node design, statistical capabilities, and compatibilit

A method for security inspection of baggage and/or personal items and a kit of parts include a detachable single-use inlay and an X-ray tray of a security check, for example, at an airport. A single-use inlay as such is also described. Furthermore, this disclosure relates to use of the kit of parts and/or the single-use inlay for the prevention of transfer of pathogenic agents. At least one metal organic framework (MOF) provided on the outer side and/or inner side of the single-use inlay is adapted and arranged to detect at least one explosive or any other hazardous compound, and/or detect at least one drug.

An apparatus for cosmogenic neutron sensing to detect moisture includes a thermal neutron proportional counter. A housing is formed at least partially from a moderating material, which is positioned around the thermal neutron proportional counter. A proportional counter electronics unit is within the housing and has a preamplifier and a shaping amplifier. The preamplifier and shaping amplifier are directly connected to the thermal neutron proportional counter. At least one photovoltaic panel provides electrical power to the thermal neutron proportional counter. A data logger is positioned vertically above the thermal neutron proportional counter and proportional counter electronics unit. A signal from the thermal neutron proportional counter is transmitted through the proportional counter electronics unit and is received by the data logger. The signal indicates a moisture content within a measurement surface of the thermal neutron proportional counter.
