珠穆朗玛峰(简称珠峰)是世界屋脊,人迹罕至。分析该地区冰、雪、河水中痕量元素的浓度,对于研究地球环境中痕量元素浓度本底值、研究大气化学组成及其在各个历史时期的变化和探讨大气环流对环境污染物扩散的影响都有重要价值。显然,这一分析工作要求有高的灵敏度、高的准确度、低的空白值,并且可以同时分析多种元素,反应堆中子活化分析很好地满足了这些要求。
Everest (referred to Everest) is the roof of the world, inaccessible. The concentrations of trace elements in ice, snow and river water are analyzed to study the background of atmospheric elemental concentrations in the Earth’s environment, the atmospheric chemical composition and its changes in various historic periods, and the effects of atmospheric circulation on the diffusion of environmental pollutants Impact has important value. Obviously, this analysis requires high sensitivity, high accuracy, low blank values, and the ability to analyze multiple elements simultaneously, and the reactor neutron activation analysis well meets these requirements.
