    摘要: A radiation detector (100) includes an insulating substrate (110), which includes a material that undergoes a change in an electrical property when subjected to ionizing radiation. A conductive film (112) is disposed in relation to a surface of the substrate. The conductive film (112) has a resistance that is a function of a state of the electrical property. A resistance measuring device measures resistance across the conductive film (112). The resistance measured by the resistance measuring device indicates an amount of ionizing radiation to which the substrate (110) has been subjected. In a method of determining exposure to a type of radiation, a boron nitride substrate is exposed to a radiation environment. A resistance is measured across a conductive film disposed in relation to the boron nitride substrate. Radiation exposure is calculated as a function of the resistance.

    摘要: A neutron detector system, with a detector having a pair of spaced diamond detector layers, sandwiched between outer silicon layers. In response to incident neutrons, the detector system measures pulse heights and response times, and from those measurements, calculates the carbon recoil energy and time of flight of scattered neutrons. This data is further used to calculate a “direction cone”, which represents the approximate angle of arrival of the incident neutron. These direction cones can be used to image neutron events.

The detector further includes an open dielectric structure pattern layered over one of the first or second electrodes and a current-limiting quench resistor coupled in series to one of the first or second electrodes. The detector further includes a power supply coupled to one of the first or second electrodes and a first discharge event detector circuitry coupled to the one of the first or second electrodes for detecting a gas discharge counting event in the electrode.

In such systems, the radiation sensitive device includes a radiation sensitive material and a plurality of resonance elements positioned on the radiation sensitive material. Methods for detecting a presence of a special nuclear material include positioning a radiation sensitive device in a location where special nuclear materials are to be detected and remotely interrogating the radiation sensitive device with a sensor.

    摘要: A plasma panel based ionizing-particle radiation detector includes a first substrate and a second substrate coupled to the first substrate by a hermetic seal. The second substrate is an ultra-thin substrate. The detector further includes a discharge gas between the first and second substrate and at least one second electrode electrically coupled to a first electrode and defining at least one pixel with the first electrode. The second electrode is coupled to the first substrate and a first impedance is coupled to the first electrode. The detector further includes a power supply coupled to at least the first or second electrode and a first discharge event detector circuitry is coupled to at least one of the first or second electrodes for detecting a gas discharge counting event in the electrode. The detector further includes a plurality of pixels, each pixel capable of outputting a gas discharge pulse upon interaction with ionizing-radiation. Each gas discharge pulse is counted by the detector as having approximately an equal value and circuitry detects if a gas discharge pulse is output from the pixels, and counts each gas discharge pulse as an individual event.

    摘要: A detector for ionising radiation comprises first (10) and second (12) diamond detector elements which are connected to a common contact (14). The two detector elements are of differing thickness and are optimised for the detection of different types of radiation, so that the detector simultaneously provides two output signals indicative of different kinds of radiation incident on the detector.

    摘要: A method for detecting ionizing radiation by allowing the radiation to affect the surface of the floating gate of a MOSFET transistor through an air or gas space. For this purpose, an uncovered area is formed on the surface of the floating gate of the MOSFET transistor forming the detector. The MOSFET transistor is used so that a charge is formed on its floating gate, the charge changing as a result of the ionizing radiation the transistor is exposed to. The radiation dose is determined by the change which takes place in the charge on the gate.
