摘要： A radiation measuring device capable of identifying the incident direction of a radiation ray and energy (segmentation). The directivity characteristics of a plurality of detectors are different from each other. A plurality of energy segmentations are set respectively for a plurality of spectra corresponding to a plurality of detectors, and actual measurement ratio information (a plurality of actual measurement counting ratios) expressing the mutual ratio between integrated counting values for each energy segmentation is computed. The actual measurement ratio information is checked against a plurality of response functions, and, when the compatibility relation between specific actual measurement ratio information and specific theoretical ratio information is found, the incident direction of a radiation ray and an energy segmentation are identified based on that relation.

摘要： A direction finding radiation detector for detecting the direction of incidence of radioactive rays, comprising: a plurality of scintillators (41, 42, 43) (101, 102, 103) made of the same material, being arranged to overlap circumferentially at least in part so that they are shadowed by each other from radioactive rays incident in circumferential directions and so that light emitted from one of the scintillators is not incident on the other scintillators; and photoreceptor devices (51, 52, 53) (111, 112, 113) having light receiving surfaces optically coupled to the respective scintillators, wherein a combination of proportions of radioactive rays incident directly on the respective scintillators and radioactive rays incident indirectly thereon, being shadowed by the other scintillators, varies with the direction of incidence circumferentially. This achieves weight saving of the detector, improves the detection efficiency of the radioactive rays, elaborates detection information through measurements in half the circumferential directions or all the circumferential directions, and simplifies setting for improved operability.

摘要： A classification apparatus including a magnetic stirrer composed of main body (1) and rotor (2) and, arranged on the main body of the magnetic stirrer, classification tube (3). The interior of the classification tube is provided with classification compartments (A-E) partitioned from each other by divider plates (5a-5b). The lowermost classification compartment (A) is furnished with gas emission conduit (7). In the classification compartment (A), the rotor (2) of the magnetic stirrer is arranged. From gas supply source (8), a high-pressure gas is fed into the gas emission conduit. By means of the gas emitted from the gas emission conduit, a vortex flow rising from the lowermost classification compartment sequentially toward higher classification compartments is generated in the classification tube. Simultaneously, the rotor of the magnetic stirrer is rotated, so that powdery substance (O) within the classification compartment (A), while being conveyed by the vortex flow, undergoes particle size classification in each of the classification compartments.
