    Abstract: PROBLEM TO BE SOLVED: To provide an optical sensor device having the simple constitution for detecting the light from a light source with constant detecting sensitivity regardless of axial dislocation of the light source. SOLUTION: This optical sensor device has an optical sensor 2 having a prescribed light receiving area and a condensing lens 1 for introducing the light into this optical sensor, and is characterized by keeping light receiving sensitivity of the optical sensor almost constant regardless of the axial dislocation of the light source 3 by arranging the light receiving area of the optical sensor in a position dislocated from a focal position of the condensing lens particularly on the optical axis of the condensing lens.

    Abstract: PURPOSE:To reduce a background noise and detect a minute amount of radioactive rays with a good signal-to-noise ratio by providing a radioactive ray shield close to the inner side of a sealing member to seal up the end opening of a cathode pipe. CONSTITUTION:An electron tube is composed by providing a cathode pipe 12, an anode pin 14 penetrating through the cathode pipe 12 in the axial direction, lead soft glasses 16 to seal the openings 12A and 12B on both ends of the cathode pipe 12, and the like, and it measures the radioactive ray amount incident into the cathode pipe 12. And at the inner side of the lead soft glasses 16 or the like to seal the both end openings 12A and 12B of the cathode pipe 12, radioactive ray shields 18 are provided to shield the radioactive rays generated spontaneously from the lead soft glasses 16 and the like, and their incidence to the measuring space in the cathode pipe 12 is prevented. Consequently, a background noise is reduced, and a minute amount of radioactive rays can be detected with a good SN(signal-to-noise) ratio.

    Abstract: PURPOSE:To enable arbitrary measurement of either dose equivalent or exposure by mounting a measuring cap and a compensating cap on the respective entrance window portions of a GM measurement detection portion and a GM compensation detection portion to attach and detach the measuring and compensating caps. CONSTITUTION:With a GM measurement detection portion 22 and a GM compensation detection portion 24, a measuring cap 20 which meets the conversion curve of dose equivalent in a low energy region at measuring the dose equivalent and a compensating cap 25 which limits exposure in a low energy region with sensitivity characteristics obtained from the GM compensation detection portion 24 are mounted on entrance windows 22a, 24a. At measuring exposure, the measuring cap 20 is mounted on the entrance window portion 22a only of the GM measurement detection portion 22 to operate and output an output difference from the result of radiation detection of each detection portion. Accordingly, the conversion curve of dose equivalent or the characteristics of exposure can be obtained. It is thus possible to perform arbitrary measurement and direct reading of either dose equivalent or exposure.

    Abstract: PURPOSE:To prevent the characteristics of a radiation detector of sealed type from deteriorating due to the inflow of air into the detector, by heating the detector and discharging gas out of it after the assembly of the detector, then cooling the detector, and applying an organic paint thereto. CONSTITUTION:After the assembly of a radiation detector of sealed type, an evacuation pipe 7 is connected to an evacuator so that the interior of a casing made of a body 1, lid plates 3, 4, etc. is removed of gas to as high a vacuum as possible. At the same time, the casing is covered with a furnace to heat the casing to remove gas occluded by the body 1 and the lid plates 3, 4. After that, the casing is cooled to a low temperature which is in the range from the room temperature to 150 deg.C, the removal of gas is continued, and an appropriate organic paint 11 such as an epoxy resin paint is applied as thick as possible to the exposed portion of an inorganic adhesive 8 and the extensive vicinity of said exposed portion. Desired ionized gas is then introduced into the casing from the evacuator through the evacuation pipe 7 so that the gas has appropriate pressure in the casing. The exhaust pipe 7 is then pressed and deformed at a desired portion and cut off, thus completing the proportional counter.
