CONSTITUTION: The waste gas contg. radiative iodine is treated through a packed filter of an adsorbent (e.g. zeolite) wherein metal (e.g. silver) or a metal lic (e.g. silver) compds. allowing to react with iodine is adhered thereon and the following three conditions are simultaneously satisfied. u≤24/dp
2 , u≤10
5 ×dp
2 , u≥0.2 but dp is the average particle size (mm) of the adsorbent and (u) is the linear velocity (cm/s). As a result, the radiative iodine discharged from the nuclear power installations can be effectively removed.

摘要： PROBLEM TO BE SOLVED: To provide a measuring apparatus measuring an individual's exposure dose and its calibrating method in an accelerator or the like irradiating energy higher than energy radiated from a nuclide used in calibration of a common radiation measuring apparatus. SOLUTION: Exposure dose of people performing maintenance by stopping the accelerator or the like are measured more accurately to determine an exposure dose more accurately when an accident or the like occurs and reflect it on medical treatment or the like. This glass dosimeter has a plurality of shields 31A laminated on a glass dosimetric element 31. Calibration is performed by using a corpuscular ray treating device which is to be actually used.

摘要： PROBLEM TO BE SOLVED: To reduce working man-hours by mechanically discriminating the presence or absence of abnormality in radiation environment, when carrying out periodical inspection in nuclear power stations or the like. SOLUTION: This radiation environment monitoring system is composed of a wireless radiation measurement device 1, a control device 5, a storage device 4 that are installed in a working place, and radiation state display parts 6 and 7 that are installed in the working place and a control room. The change forecast value of the dose equivalent weight rate of the working place is kept in time series (for each working step or the like), and a measurement value, measured by a measuring instrument placed at a plurality of places, is compared with the next change forecast value in time series, thus judging the degree of progress in time series, continuously comparing an estimated dose equivalent weight rate in matching with the degree of progress with the measurement value at all times, and monitoring and displaying the presence or absence of the abnormality of the dose equivalent weight rate of the working place.

摘要： PROBLEM TO BE SOLVED: To accurately measure both a surface dose equivalent rate and a one-meter-position dose equivalent rate without manual assistance. SOLUTION: A waste storing container 10 is set in a shielded assembly 20 inside a dryer separator pool 7, a surface dose equivalent rate of the container 10 is measured in a condition shielded from an outside, a dose equivalent rate in one-meter position is estimate-operated to be measured, and a radiation controlling person is not required therefore to get into the container 10 for the purpose of measurement, so as to reduce an exposure amount to the person and to be free from danger. Since measured in the shielded assembly 20 provided inside the pool 7, an influence of the radiation from an outside of the assembly 20 is eliminated to conduct accurately the measurement.

摘要： PROBLEM TO BE SOLVED: To prevent erroneous entry and to enable the monitoring of the pres ence of anomalies in workers by supplementing a radiation control notebook with an on-line computer system. SOLUTION: The computer of an employer business undertaker 4, etc., is connected to the main computer of a central registration center over a line, various data is registered at the mine computer simultaneously with entry in a radiation control notebook. In the case of undergoing health examination, the employer business undertaker 4 registers its results to the main computer from a terminal for input and enters them in the radiation control notebook. In addition, after the completion of operations, the final values of radiation exposure doses are entered in the radiation control notebook and are simultaneously inputted from the terminal for input. By this, the detailed results of health examination are recorded, and temporal changes are tracked to enable the detection of anomalies. The reliability of the radiation control notebook is improved to be useful for the prevention of radiation hazards.

摘要： PROBLEM TO BE SOLVED: To eliminate anxiety of operator worrying of being exposed to radia tion by preliminary inputting the concentration ratio of radioactivity in the emissivity of radiation and the counting efficiency of radiation of each nuclide in reactor water to a computer. SOLUTION: After the completion of measurement, a bed 2 is moved to the outside of a shield 4 by means of a controller 7, and the result of radioactivity measurement unit 8 outputs measured data to a printer 9. With the unit 8 the different method is used, information such as the nuclide ratio of radioactivity, the counting efficiency of each radiation, gamma ray emissivity, biological half life in reactor water is inputted and the output is made at milli Sievert(mSv). Accordingly the measurement result obtained after an operator has an anxiety when he/she performs the measurement in the housing of made of iron or steel is always a very small numerical value of 0.015-0.5mSv, which is used as a counting number for a specified time (normally 10,000-20,000 count), so that he can feel at ease.

摘要： PURPOSE:To implement an inexpensive, highly reliable, ultrasonic wave type device for simultaneously measuring a flow rate and temperature, by adding a simple circuit to a means, which measures the flow rate by ultrasonic waves. CONSTITUTION:A signal is sent to a detector 3 and a receiving circuit 12 from a transmitting circuit 11 through a switch 10. The receiving circuit 12 measures a time t1, during which an ultrasonic wave is propagated from the detector 3 to the detector 4, and a time t2, during which the ultrasonic wave is propagated from the detector 4 to the detector 3. A flow speed operating circuit 13 computes V, and a flow rate Q operating circuit 14 computes Q. Meanwhile, a C cos theta operating circuit 15 computes C cos theta by using the signal, which is generated by the operating circuit 13 and the like. A temperature T operating circuit 18, which is a function generator, obtains a liquid temperature T based on a flag (i) obtained by a flag setter 17 and the C cos theta from the operating circuit 15. Thus, an inexpensive, highly reliable device for simultaneously measuring the flow rate and temperature can be implemented.
