Dose rising process at the northwest direction from the plant: Distributions of air dose rate, rain intensity, and concentration of I-131 accumulated in vertical air column (2-D animations)

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.
