1.前言自从去年(?)月我国第一个原子反应(?)开始运转以来,我国已能自己大量地生产对工农业和科学研究上很有用处的放射性同位素。放射性同位素的用途很广,已在医学、农业、化学、冶金和土木等各个部门广泛地应用着。本文系根据目前搜集到的文献资料,就放射性同位素在港工上——特别是在观测漂砂时应用,作一个简单报导,以供有关工程技术人员的讨论和参考。
1. Foreword Since the first atomic reaction in our country (?) Began last month (?), Our country has been able to produce on its own extensive mass production of radioisotopes that are of great use to industry, agriculture and scientific research. The use of radioisotopes is very broad and has been widely used in various sectors such as medicine, agriculture, chemistry, metallurgy and civil engineering. Based on the literature collected so far, this article gives a brief report on the application of radioisotopes to Hong Kong workers, especially in the observation of drift sand, for discussion and reference by relevant engineering and technical personnel.
