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.

The Japanese Standard Time (JST) is presented at the top (The Universal Time Constant (UTC): - 9 hours).
Deposition from the atmosphere was considered in this simulation, and this caused the rapid dispersion during the early phase (12 to 20 March).
Direct discharge to the ocean from the plant was assumed to start from 21 March.
