摘要： In a radiation measurement apparatus, an analog pulse signal output from a semiconductor radiation detector is converted to a plurality of digital signals by an analog-to-digital converter for each analog pulse signal. A threshold circuit for inputting these digital signals discriminates digital signals exceeding a threshold value. A digital signal integration circuit integrates the plurality of discriminated digital signals for each analog pulse signal and obtains an integrated value for each analog pulse signal. A spectrum generation circuit for inputting the respective integrated values generates a radiation energy spectrum using the integrated values and accurately performs the quantitative analysis and energy analysis of a radioactive nuclide using the radiation energy spectrum. A quantitative analysis and an energy analysis of a radioactive nuclide can be accurately performed while a time resolution of a radiation detector can be maintained.

摘要： A fuel assembly radiation measuring apparatus has a radiation signal generation apparatus including a LaBr3(Ce) scintillator, an A/D converter, a signal processing apparatus, and a data analysis apparatus. The signal processing apparatus has a FPGA and a CPU. γ rays emitted from a fuel assembly disposed in water in a fuel pool enter into the LaBr3(Ce) scintillator that emits scintillator light, then a photomultiplier tube converts the light into an electric signal as a radiation detection signal. A pulse height analyzer of the FPGA inputs a radiation detection signal having a digital waveform generated by the A/D converter and changes the digital waveform into a trapezoid waveform to obtain a maximum peak value. The data analysis apparatus quantifies a target nuclide using a plurality of inputted maximum peak values to obtain burnup.

摘要： There are provided a radiation detection module, a printed circuit board, and a radiological imaging apparatus which make it possible to enhance spatial resolution without increasing channel number, and thereby to perform high-accuracy diagnosis. The radiation detection module includes a plurality of radiation detectors, and a wiring board on which the plurality of radiation detectors are mounted in a manner of being arranged in at least a radiation traveling direction. Here, on the wiring board, a pair of the radiation detectors which are adjacent to each other in the radiation traveling direction are electrically connected to each other, thereby configuring one detector structure (i.e., detection channel). Moreover, the radiation detectors are mounted onto the wiring board such that respective connection parts of electrodes, which are to be electrically connected to each other, are in a mutually-facing state.
