Abstract: This paper describes the most common presently used methods for detecting uranium and plutonium isotopes after their introduction to environment. Known isotope ratios of U and Pu in different nuclear events are important tool for characterizing the sources of nuclear material. Detection techniques both in field and in laboratory are presented, as well as different models that can be used for identifying the origin and age of the nuclear material. Identification of the source of nuclear material in environmental samples is needed for estimating the quality and quantity of the nuclear hazard. This information is essential in risk assessment and crisis management, in chemical, biological, radiological and nuclear (CBRN) research after e.g. a terrorist attack, in radioecology and environmental radioactivity research.
