IAEA project aims to develop polymer irradiation model
The International Atomic Energy Agency has launched a new coordinated research project (CRP) aimed at creating a database of polymer-radiation interactions in the next five years with the long-term goal of using the database to enable machine learning–based predictive models.
Radiation-induced modifications are widely applicable across a range of fields including healthcare, agriculture, and environmental applications, and exposure to radiation is a major factor when considering materials used at nuclear power plants.

Extended x-ray absorption fine structure(EXAFS) spectroscopy can be used to probe thelocal atomic environment around actinide atoms in avariety of systems. Uranium LIII-edge spectra wereobtained on an in-lab rotating anode EXAFS facility.Spectra of crystalline UO2F2 and aqueous solutionscontaining hexavalent uranium ions show structureassociated with two separate shells of surroundingatoms. With the use of fluorescence detection techniques and more research directed toward deter¬mining backscattering amplitude and phase shiftparameters, it is anticipated that EXAFS will becomea powerful quantitative technique for structure stud¬ies in heavy atom systems.
