【英国《原子》1985年4月号报道】英国哈威尔核应用研究中心将在一个展览会上展示其用于煤炭工业的最新技术。该研究中心为煤田勘探研制了一种井孔探测电子学仪器,用来探测煤矿中的硫含量。其原理是,用中子源使矿层活化,然后探测出所有被激活的硫所放出的特征γ射线,探测所得的信息被迅速加工处理成反映 [April, UK, April 1985] The Harwell Institute for Nuclear Applications at the United Kingdom will demonstrate its latest technology for the coal industry at an exhibition. The research center developed a borehole exploration electronics instrument for coalfield exploration to detect sulfur content in coal mines. The principle is that the mineral layer is activated with a neutron source, and then all the characteristic gamma rays emitted by the activated sulfur are detected. The detected information is rapidly processed and reflected.
