Photoneutron activation analysis applied for environmental researches

摘要

An instrumental highly sensitive photon activation method based on the (, n)reactions and following gamma-ray spectrometry analysis for the multielement determination fromseveral environmental media is developed. The environmental samples and standards were irradiatedsimultaneously for 4 hours with 24 MeV bremsstrahlung produced by the MT-25 linear electronaccelerator of the Flerov Laboratory for Nuclear Reactions of the Joint Institute for NuclearResearches. The analytical results for up to 32 elements in the analyzed samples are presented.
