美国研发辐射监测仪,可精确检测放射污染

近日,美国俄亥俄州立大学工程学院研发出一种新型的辐射监测及检测仪器,该仪器能更精确地检测出核环境下的放射性污染程度,同时,它的造价将低于以往产品,并且拥有卓越的检测速度。

 

目前,这种新型的辐射分光仪已获得专利,第一批产品也将于不久面世。而新技术也为阿维森纳设备公司带来了新业务,这个位于俄亥俄州的公司将依托俄亥俄州立大学的研究技术生产相关部件。相关研究人员表示,这种辐射分光仪将最终向全球推广,全球相关行业都能运用这种新技术。俄亥俄州立大学有害辐射防护学教授戴维·汉拜表示,相比以往的检测仪,新型分光仪的工作效率将更高,它能同时检测并定量伽马射线和贝他射线,而在此之前,要想同时检测这两种射线,必须有两台不同的检测仪器和其他的化学测试,这是个相当耗时的过程。“新型设备能在15分钟内对检测对象给出精确结果,而以往这一过程需要半天,新设备不仅简化了流程,还节省了时间和金钱。”

 

这一新型分光仪是戴维·汉拜和阿比·福森尼耗时10年的研究成果,阿比·福森尼是俄亥俄州立大学工程学院的副教授。新型分光仪能快速辨别出测试物中所含放射性核素的种类和数量。通过对土壤样本的检测,分光仪显示出该土壤样本含有铯137及锶90这样的污染物,而这些都是产自核反应堆中。此外,分光仪还能辨别伽马射线和贝他粒子,而这是鉴定污染级别的必要环节。

 

戴维·汉拜表示,这一系统最终能用于检测核能行业的辐射情况,同时也能应用于医学界的放射性跟踪研究。

 

俄亥俄州立大学工程学院目前已与德克萨斯州的Ludlum设备公司签订合同,用以生产第一批设备,俄亥俄州立大学技术转让办公室也希望能获得许可证以用于商业开发目的。另外,分光仪的电子系统将由阿维森纳公司生产。
