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.

Integral neutron capture and neutron fission cross sections have been measured for the 276-day 254gEs. Thermal cross sections and resonance integrals were evaluated using a cadmium filter technique. Capture cross sections were determined from alpha-particle spectrum measurements following neutron irradiations with cobalt flux monitors. Fission cross sections were measured using fission track detection techniques with 233U monitors. The fission cross-section values compared favorably with an absorption cross-section determination from a burnout experiment of 253Es-254Es. The integral neutron capture and fission cross sections determined for 254gEs are: = 28.3 ± 2.5 and Ic = 18.2 ± 1.5 b, and = 1970 ± 200 and IF = 1200 ± 250 b.
