摘要： A system for determining a radiation dose in real time can include at least one three- dimensional target object to be exposed to ionizing radiation. The at least one target object may include a scintillating gel material. The scintillating gel material may emit light when exposed to the ionizing radiation. An imaging system may be configured to capture at least a first image of the target object from a first position, and a second image of the target object from a second position relative to the target object. A controller may be connected to the imaging system and may be configured to the process the first and second images to provide a three-dimensional dose distribution in real-time.

摘要： The invention resides in an apparatus comprising an LED light source (134) for emitting a green illumination light (132) for illuminating an optically stimulated luminescence (OSL) sensor, a photodetector (162) for detecting of green luminescent light emitted by the OSL sensor, a pulse counter for counting photon pulses generated by a photodetector based on photons of luminescent light emitted by the OSL sensor and counted by the photodetector, and a microprocessor (166) for controlling the LED light source and the photodetector and the pulse counter. The microprocessor controls when the LED light source, the photodetector and the pulse counter are switched between an on state and an off state. The pulse counter is part of the microprocessor, and the microprocessor determines a radiation dose of one type of ionizing radiation to which the OSL sensor has been exposed based on the photon pulses counted by the pulse counter.

摘要： Provided is a measurement unit and measurement method for reducing attenuation due to optical fiber length and SN degradation due to background in a dosage rate monitor that uses optical fiber. This system comprises: a radiation detector for detecting radiation dosage; a light source for irradiating stimulating light on the radiation detector; a photodetector for detecting light generated by the radiation detector; an optical fiber for connecting the photodetector and the radiation detector and light source, and transmitting light from the light source and light from the radiation detector; a measurement unit for counting the pulses outputted from the photodetector; and an analysis unit for extracting the luminous energy originating from the radiation detector, from time information, wave height information, and the count value, which are measurement results obtained by the measurement unit, and converting the luminous energy to a dosage and dosage rate.

摘要： A method of determining the doses of neutrons, gamma and X-ray photons, beta, alpha and other ionizing radiations using a method of image processing in spatial and frequency domain that produces parameters that are related to the radiation dose absorbed in a luminescent material. Portions of the luminescent material may be covered by different converters to allow for doses of different radiations to be discriminated.
