放射性探测仪器在铀矿普查中得到了广泛的应用,这类仪器近几十年来世界各国都有了较完整的系统。为了对国外近几年来这门技术发展的情况有所了解,这里仅就最近在文献中所见到的一部分国外关于放射性探测仪器在铀矿普查中的应用情况概括地作些介绍。1.地面普查仪器在铀矿普查工作中,苏联曾广泛使用УР-4М,ПГР等类仪器,此类仪器仍有其优点,目前在使用中还有一定意义,但是,在普查仪器的研究与制造方面,最近已 Radioactive detection instruments have been widely used in the uranium mine survey. Such instruments have a relatively complete system in all countries in the world in recent decades. In order to understand this technological development abroad in recent years, we will only briefly introduce some foreign applications of radiological detection instruments in the uranium mine survey that we recently saw in the literature. 1. Ground Census Instruments In uranium census work, the Soviet Union has been widely used УР-4М, ПГР and other types of equipment, such instruments still have their advantages, there is still some significance in the use, but the census instrument research and Manufacturing, recently has
