由中国核工业总公司404厂石家庄辐射中心研制的一种高精度的核子秤——SY—5000型智能式闪烁核子秤已在京通过了中华人民共和国计量器具新产品定型鉴定。 由于SY—5000型核子秤采用了线状放射源和高灵敏、高效率的闪烁探测器,首创了新型的自动稳峰技术,因此,其性能指标有了重大突破。 根据中国计量科学研究院的测试检定结果表明,该仪器的动态计量精度为0.15%,远远优于国际法制计量组织所颁发的核子秤技术标准中最高准确度等级所规的技术指标 By the China National Nuclear Corporation 404 Factory Shijiazhuang Radiation Center developed a high-precision nuclear scale - SY-5000-type intelligent scintillation nuclear scale has passed the People’s Republic of China measuring apparatus new product stereotypes identification. SY-5000 nuclear scale with linear radioactive sources and high sensitivity, high efficiency scintillation detector, pioneered a new type of automatic steady peak technology, therefore, its performance indicators have been a major breakthrough. According to the test results of China Institute of Metrology, the dynamic measurement accuracy of this instrument is 0.15%, much better than that of the highest accuracy level of the technical standards for nuclear scale issued by the International Organization of Legal Metrology
