Article Synopsis
- Researchers measured sediment cesium-137 concentrations near the Fukushima Daiichi Nuclear Power Plant from 2011 to 2017, noting high levels initially but a decrease in seven stations over time.
- They identified 25 radioactive cesium-bearing microparticles (CsMPs), with their contribution to sediment samples varying significantly, particularly lower in the southern part of the plant compared to the northern part.
- The study suggests that while many small CsMPs in the south dispersed shortly after the accident, larger, more persistent CsMPs likely accumulated in the northern region due to the sediment's characteristics.
