Uranium and plutonium isotopes were measured in soils, sediments and waters in an area subject to the past and present discharges from the uranium conversion plant of Malvési (France). The isotopes (236)U and (239)Pu are well known activation products of uranium and they prove to be powerful tracers of spent fuel releases in soils and sediments. On the other hand (234)U and (238)U activities measured in waters can be used to distinguish between releases and background uranium sources. Such findings contribute to improve the monitoring of the actinides releases by nuclear fuel facilities (mining sites, conversion, enrichment and fuel plants, reprocessing plants).
在法国马尔韦西铀转化厂过去和现在都有排放的一个区域，对土壤、沉积物和水体中的铀和钚同位素进行了测量。同位素236U和239Pu是众所周知的铀活化产物，它们被证明是土壤和沉积物中乏燃料释放的有力示踪剂。另一方面，在水体中测量的234U和238U活度可用于区分释放的铀和背景铀源。这些发现有助于改进对核燃料设施（矿场、转化厂、浓缩厂和燃料厂、后处理厂）中锕系元素释放的监测。
