The use of nuclear analytical techniques for environmental studies in South America is selectively reviewed since the time of earlier works of Lattes with cosmic rays until the recent applications of the PIXE (particle-induced X-ray emission) technique to study air pollution problems in large cities, such as São Paulo and Rio de Janeiro. The studies on natural radioactivity and fallout from nuclear weapons in South America are briefly examined.
本文对南美洲环境研究中核分析技术的应用进行了选择性回顾，时间跨度从早期拉特斯利用宇宙射线开展的研究，直至近期质子激发X射线发射（PIXE）技术在圣保罗和里约热内卢等大城市空气污染问题研究中的应用。文中还简要考察了南美洲关于天然放射性和核武器沉降物的研究。
