Identification of Pu and U isotopic composition and its applications in environmental and CBRN research

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 Pu in different nuclear events are important tool characterizing sources material. Detection techniques both field laboratory presented, as well models that can be identifying origin age Identification source material environmental samples is needed estimating quality quantity hazard. information essential risk assessment crisis management, chemical, biological, radiological (CBRN) research e.g. a terrorist attack, radioecology radioactivity research.
