【《国际原子能机构通报》1982年40卷3期第9页报道】国际原子能机构创建时,几乎还没有运用核技术研究水文问题。在过去二十五年中核技术的应用范围大大扩展了。早先,同位素水文技术曾用来测量河水流速。只是在近期才清楚地看出,放射性同位素技术特别适合急湍的河流。今年,国际原子能机构根据机构本身的技术合作计划,在坦桑尼亚采用氚作为示踪剂实施这样一项任务。与早期的工作使用的γ辐射体不同, [IAEA Bulletin, 1982, Volume 40, Number 3, Page 9] At the time of the founding of the IAEA, there was little or no use of nuclear technology to study hydrological issues. In the past twenty-five years the scope of application of nuclear technology has greatly expanded. Earlier, isotope hydrology was used to measure river flow. It is only recently clear that radioisotope technology is particularly well suited to the rapids of rivers. This year, the International Atomic Energy Agency adopted tritium as a tracer in Tanzania to implement such a task based on its own technical cooperation program. Unlike the gamma emitters used in earlier work,
