A radiation dosimetry method and associated devices for carrying out the method are disclosed herein. More particularly, a method and associated apparatus which compensates for variations in amounts of a radiation sensitive material in a radiation dosimetry film is provided.
摘要:
The invention relates to a radiation-detecting device comprising at least two radiation detectors(D 1 , D 2 , D 3 ) distributed in series along a support cable (MB), each detector comprising an optically stimulated luminescence detection element which is optically coupled to at least one optical fibre (F 1 , F 2 , F 3 ), each optically stimulated luminescence detection element being held opposite a first end of the optical fibre by a mechanical part fixed to the support cable, the mechanical part being held in a flexible cable (FL) by holding means, the second ends of each optical fibre leading to the same first end of the flexible cable.
摘要:
The present invention uses the concept that radiation-sensitive material (4) embedded in a disposable radiochemistry device gives the device the additional capability of recording radiation dose, for readout at a later time. The invention provides a device comprising at least one piece of a radiation-sensitive material (4), and a method to measure the radiation dose associated with radiolabelled compound produced by said device.
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:
The present invention relates to a photoexcitable storage phosphor which comprises at least one rare earth element in the trivalent +3 oxidation state and wherein upon irradiation by X- ray, ?-ray or UV radiation the trivalent +3 oxidation state is reduced to divalent +2 oxidation state. The present invention also relates to a dosimeter, radiation image storage panel comprising the phosphor of the present invention and in dosimetry applications for applications including scientific, medical and other imaging applications. The present invention also relates to a process for making a photoexcitable storage phosphor and a process for recording and reproducing an image.
