针对200L桶装放射性废物的中子测量检测新装置(图1)已在今年研制完成。该装置主要用于对放射性固体废物进行α废物分类检测。采用无源中子测量模式,通过探测桶装放射性废物发射的中子来计算废物所含核素的量,进而得到该桶废物α核素比活度,对比国家放射性废物分类标准,区分出α废物和非α废物,为下一步处理处置提供重要参考依据。 The new device for neutron measurement testing of 200L barrels of radioactive waste (Figure 1) has been completed this year. The device is mainly used for radioactive solid waste α waste classification test. The passive neutron measurement mode is adopted to calculate the amount of nuclide contained in the waste by detecting the neutron emitted by the barrel of radioactive waste so as to obtain the specific activity of the nuclide α nuclide and to compare the national radioactive waste classification criteria to distinguish α Waste and non-α waste, for the next treatment provides an important reference.
