a_chenDue to the mass destruction of the area, the first few days’ data were not able to collect (not only the destruction, but the rescue was the first priority). Therefore, the scientific committee used models to simulate and analyse the data (might not be accurate on the early stage). After the rescue, many countries have provided data to assist the works. For the long‐live radioactive substances, the data was able to collect with the ground soils. Furthermore, prediction can be made with the pass experiences and the basic models.
