Abstract: When a heating process is performed in a state where a thermal transfer sheet is superimposed on a scintillator plate (16), a film of the thermal transfer sheet is separated from the thermal transfer sheet and adhered onto the scintillator plate. The film includes a protective layer (24), an aluminum layer (26), and an adhesive layer (28). The aluminum layer is protected by the protective layer. Because the scintillator plate by itself functions as a rear surface support substrate with respect to the protective layer and the aluminum layer, a film which is highly resistive against an external effect can be formed. A plurality of films can be layered on the scintillator plate. A pressure transfer method can also be used for formation of the film. A scintillator member in which the film has been formed is disposed in a radiation measuring device.

Abstract: PROBLEM TO BE SOLVED: To enable a radiation-measuring apparatus, for detecting γ-rays to measure in a low energy region by reducing cutting energy. SOLUTION: Output pulses from a radiation detector 20 and a plurality of radiation detectors 22 are bound and are counted at an OR circuit 24. The radiation detectors 22 detect charges generated by radioactive rays in a radiation detection semiconductor element 42, without being converted to a light at a scintillator, while conversion into the light at the scintillator is interposed in the radiation detector 20. A lower cut level can be set to the radiation detectors 22 than to the radiation detector 20 because of this difference of methods of detecting the radioactive rays. The measuring apparatus has a measuring range extended towards the low energy side.

Abstract: PROBLEM TO BE SOLVED: To accurately detect a rare gas in an off gas being emitted from a reactor. SOLUTION: Piping 10 is provided with a radioactive gas monitor, which is composed of a plurality of detectors 12. Each of the detectors 12 is composed of a scintillator block 14 and a photomultiplier 16. Since a plurality of detectors 12 are provided so that the surrounding of the piping 10 is surrounded, a pair of 511 keV γrays being generated due to the annihilation of a proton that is emitted from 13N can be detected by either detector 12 even if the rays are scattered by the piping 10. As a result, the γ rays can be simultaneously counted and can be effectively excluded from a detection result.

Abstract: PROBLEM TO BE SOLVED: To estimate crosstalk form other non-measuring sample and obtain true count value for each sample in a device, for which a plurality of racks are arranged on a rack table and each sample held on the rack is measured with detecting units. SOLUTION: Traversing detection units 20, a rack carriage route is set and each sample position on the rack carriage route is defined as evaluation positions. At each evaluation position, crosstalk contribution fraction is determined in advance based on the geometrical relation to the detection units 20 and the crosstalk of each sample is estimated based on the crosstalk contribution fraction. In actual operation, matrix operation equation utilizing reverse crosstalk matrix is used.

Abstract: PROBLEM TO BE SOLVED: To provide a counter which enables measurement with good reproducibility with a whole body counter of a sitting type. SOLUTION: The back rest 12 of a measuring chair 10 is provided with two sets of photocouplers 30 in the positions of the heights nearly corresponding to the waist and chest of a testee. When both of the light emitting part and light receiving part of two sheets of these photocouplers 30 are shielded by the body of the testee, judgment is made that the testee sits in a correct posture on the measuring chair 10. Measurement of radiations is then executed. The measurement is made only when the testee sits in the correct posture on the measuring chair 10, by which the reproducibility of the measurement is enhanced.

Abstract: PURPOSE: To provide a dust monitor which can accurately detect in real time the concentration of artificial radioactive nuclide to a very low level even in such an environment that the concentration of natural radioactive nuclide, such as the radon, etc., is high and has excellent detection limit performance. CONSTITUTION: An α-ray detector 20 and γ-ray detector 30 respectively detect α-rays and γ-rays from the dust collected on a sheet of sampling filter paper 12. An α-ray measuring section 24 counts the output pulse of the detector 20. The found α-ray counting rate indicates the amount of natural radioactive nuclide in the dust. A γ-ray measuring section 34 find the energy spectrum of γ-rays from the dust by performing pulse-height analysis on the output pulse of the detector 30. An arithmetic processing section 50 finds the contributing amount of the natural radioactive nuclide to the γ-ray counting rate by multiplying the α-ray counting rate found by the measuring section 24 by a prescribed conversion factor and the real γ-ray counting rate of artificial radioactive nuclide by subtracting the contributing amount from the γ-ray counting rate. The concentration of the objective nuclide in the dust is found by using the real counting rate.

Abstract: PURPOSE: To undertake the radiation measurement of a liquid radioactive sample, reduce the capacity of a well for housing the sample and make thin a plate to form the well. CONSTITUTION: Suction space 16 for sucking a sample is formed between circular plastic scintillators 12 and 14 in a well 10. Open sections 18 and 20 are formed at both sides of the space 16, so as to be communicated to each other. Furthermore, the sample supplied from one open section 18 is drawn into the space 16 and at the same time, the air is forced out from the other open section 20. A radiant ray emitted from the sample drawn into the space 16 is converted to a photon via the scintillators 12 and 14 for detection with a photomultiplier tube or the like.
