Major scientific and technological tasks and early construction of Chinese radiochemistry discipline

Since the establishment of the Institute of Radium of Peking Academy in 1932, radiochemistry has embarked on a difficult path of development in China. In 1950, with the establishment of the Institute of Modern Physics of the Chinese Academy of Sciences, the development of radiochemistry took on a new look and entered the fast lane. With the development of related scientific research tasks, the construction of the discipline of radiochemistry has entered the right track. This study takes time as the main thread and observes the process of radiochemistry from scratch and from weakness to strength in China from the perspectives of scientific workers such as Zheng Dazhang, Qian Sanqiang, and Yang Chengzong.
