Dispersion and surface deposition of I-131 over Eastern Japan (2-D animation)

Notice: This result is computer simulation based on the preliminary estimated source term and some assumptions and does not guarantee the actual distributions of radioactive materials and radiation doses. However, this result will provide helpful information to understand the condition of distributions of radioactive materials and radiological doses.
