IAEA’s Grossi joins seawater sampling at Fukushima Daiichi
International cooperation in the monitoring of radiation levels in seawater near the disabled Fukushima Daiichi nuclear power plant continues. Scientists from China, South Korea, and Switzerland were recently joined by International Atomic Energy Agency Director General Rafael Mariano Grossi as they collected seawater samples under the “additional measures” framework, which was adapted in 2024 to increase the participation of other countries and enhance the transparency of the IAEA-led analyses.

Proton emissions from the reaction of neutrons with stainless steel at a 14.6-MeV neutron energy are measured using a multitelescope system. A 1Cr18Ni9Ti (Type 321) stainless steel is used. The double-differential cross sections (DDCS) of 16 reaction angles from 25 to 165 deg are obtained in this measurement. The energy spectra and the angular distributions of proton emissions are obtained from the DDCS. The angular distributions show a slightly energy-dependent forward-backward asymmetry. The total proton emission cross section is 229 ± 16 mb for a proton energy >2 MeV.
