摘要： PROBLEM TO BE SOLVED: To provide a radiation measuring apparatus that can perform dust collection of sample gas, which is discharged from a disposal facility for volume reduction of radioactive material, by using mobile type filter paper.SOLUTION: An outside air introduction part is connected to a sample gas capturing and transferring part, which captures sample gas from a facility chimney, to introduce outside air into the sample gas and dilute the sample gas, so that an acid dew point of the sample gas after the dilution is lowered. The sample gas contains acid gas and water vapor, such that a device develops corrosion degradation at or below a temperature of an acid dew point due to generated acid, and further water vapor condenses and adheres to a flow channel, thus causing difficulties in performing correct dust collection. However, at a lowered acid dew point of the sample gas after the dilution, the temperature of the sample gas to be transferred to a dust collection part can be maintained at or above a temperature of an acid dew point of the sample gas after the dilution, and below a temperature of an acid dew point of the sample gas before the dilution. By introducing outside air to the sample gas, it is possible to use mobile type filter paper having a temperature specification of which upper limit is lower than that of fixed type filter paper, thus extending a maintenance period.
摘要翻译：要解决的问题：提供一种能够通过使用移动式滤纸来进行从废弃物处理设备排出的用于体积减少放射性物质的样品气体的集尘的放射线测量装置。
解决方案：外部空气引入部分连接到样品气体捕获和转移部分，其从设施烟囱捕获样品气体，以将外部空气引入样品气体中并稀释样品气体，使得酸露点的稀释后的样品气体降低。样品气体含有酸性气体和水蒸汽，使得器件由于产生的酸而在酸露点的温度或更低的温度下发生腐蚀降解，并且进一步的水蒸气冷凝并粘附到流动通道，从而导致执行正确的困难集尘。然而，在稀释后的样品气体的酸露点降低的情况下，可以将被转移到集尘部的样品气体的温度保持在等于稀释后的样品气体的酸露点的温度以上，并且低于稀释前样品气体的酸露点的温度。通过向样品气体引入外部空气，可以使用具有比固定型滤纸的上限低的温度规格的移动式滤纸，从而延长了维护周期。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a radioactive gas monitor capable of precisely measuring even a rare gas which is to be measured by making an instruction accurately follow a change in radiation concentration of an exhaust gas at a headstream point, to suppress dropping of pressure of a sample gas. SOLUTION: A sample container 52 of a detecting part 5 which shares a high measurement range includes a container bottom plate 54 containing an inlet nozzle 56 for guiding-in the sample gas and an exhaust nozzle 57 for exhausting the sample gas, and a detachable container cap 55 which is attached to the container bottom plate 54. The container cap 55 includes a detachable collimator 58 which reduces β ray released from the sample gas to a wanted rate and causes it to be incident on a radiation detector 51. The collimator 58 is arranged in projection toward the container bottom plate 54 so as not to significantly prevent a stream of the sample gas, with an incidence window 59 provided to its tip end. The detection efficiency of the radiation detector 51 is determined by the inside diameter of the collimator 58 and such an effective volume as viewed from the radiation detector 51 in the gap between the incidence window 59 and the bottom plate 54.
