Although some time has passed since massive earthquakes triggered the Fukushima Daiichi nuclear disaster, radioactive material continues to spread through the air and water. Recent reports have cited fatal levels of radioactivity in the surrounding area.
Following the disaster, ASR created a Lagrangian particle dispersal model to track radioactive seawater and relevant concentrations as well as floating debris. We recently updated the model so please check out the results. You might be surprised to see how far radioactive material and floating debris has spread from the coast of Japan and where it is heading.
