摘要： PROBLEM TO BE SOLVED: To solve a problem in terms of the quality control of an X-ray image reader that the photoelectron multiplication factor (gain) is lowered in the long-term use of a photomultiplier. SOLUTION: This reader is provided with an ordinary reading mode for reading a stimulable phosphor sheet with the gain of a registered photoelectric conversion means, a sensitivity registering mode for registering system sensitivity and a gain correcting mode, whereby the system sensitivity under a service environment condition is registered/ reregistered at the time of installing the radiograph reader in a hospital or at the time of exchanging a radiation tube, and the quality control of the radiograph reader is accurately performed. By performing the gain correcting mode, the deterioration of the photoelectric conversion means is corrected. Thus, the load of the quality of the radiograph reader is drastically reduced. Since the gain is easily corrected, time and cost are drastically improved.

摘要： PROBLEM TO BE SOLVED: To provide a device with a favorable friction-stimulative storage phosphor. SOLUTION: This device is a device for measuring pressure applied by a pressure source different from an air-contacting pressure source, or change thereof, and for reading out the pressure, the device includes a stimulative storage phosphor sheet or panel, and a means for applying the pressure onto the storage phosphor sheet or panel, the power source and the the storage phosphor panel are positioned opposedly to make the pressure generated by the pressure source or the change thereof reach to the stimulative phosphor called as a friction-stimulative phosphor, the phosphor is thereby stimulated by the pressure to emit friction-stimulated light, and the device has a capture means for capturing the friction-stimulated light and a detection means for detecting it.

摘要： PROBLEM TO BE SOLVED: To reduce a light quantity unevenness of an EL beam in a method and an apparatus for reading an image to read image information by irradiating an optical reading image detector with a linear EL beam. SOLUTION: A better conductive bus line 35 than an element 31a is brought into contact with the element 31a in a lengthwise direction of the element 31a and annexed as a 2-layer film structure on each of both side surfaces of the element 31a of the side opposed to a second electrode layer 15 of a detector 10. The line 35 and the element 31a are connected together to a light source control means 40. Since a resistance value of a combination of the element 31a and the line 35 in the lengthwise direction is reduced, a phenomenon in which a voltage between EL layers 31 in the lengthwise direction is gradually lowered from the side of the means 40 in the lengthwise direction is reduced as compared with that of the case in which the line 35 is not arranged. Thus, a light quantity unevenness in the lengthwise direction of the element 31 of the beam irradiated from the layer 32 can be reduced.

摘要： PROBLEM TO BE SOLVED: To obtain a radiation detector in which radiation images are stored in a phosphorescent screen which is stable in severe temperature and humidity conditions and has a long life time by providing a means for preventing moisture from entering an enclosure. SOLUTION: A phosphorescent screen 23 which can be stimulated by light is placed in an enclosure 22. Both a stimulating light source 24 for stimulating the phosphorescent screen 23 and a converting element array 25 for capturing light emitted from a phosphor at the time of stimulation and converting the light into an electric signal are provided. A means for moving an assembly 27 of the stimulating light source 24, an erasing light source 26, and the converting element array 25 in a sub-scanning direction 28 is provided. In addition, a means 29 for transmitting the electric signal output of the converting element array 25 to an external signal processing device is also provided. N2 gas is flashed as a means for preventing moisture from entering the enclosure 22. The gas is compressed into a first opening 30 of the enclosure 22 from a container such as a gas cylinder and released into air through a second opening of the enclosure 22.

摘要： PROBLEM TO BE SOLVED: To provide a differential-integral type radiation measuring method based on a combination of a method using stimulable phosphor for always monitoring radiation and a method measuring radiation while integrating it for always monitoring radiation ranging from very weak one to a very intensive one caused momentarily. SOLUTION: In a radiation measuring method using stimulable phosphor, the stimulable phosphor serving as a radiation detecting medium is provided with two actions comprising an action storing incident radiation and reading out a radiation incident amount as stimulable fluorescence by excitation light and an action promptly emitting fluorescence by the incident radiation, and using these two actions, stimulable fluorescence and prompt fluorescence are detected in real time by means of a fluorescence detecting mechanism for detecting stimulable fluorescence and prompt fluorescence in time-sharing. In detection of stimulable fluorescence and prompt fluorescence in time-sharing, if an high-intensity radiation is incident in a short time and the fluorescence detecting mechanism is saturated and stops functioning, stimulable fluorescence is detected after restoration of the fluorescence detecting mechanism, so that an amount of high-intensity radiation incident in a short time can be measured.
