ON THE METHOD OF ESTIMATION OF THE POPULATION DOSE, POPULATION, AND SURFACE AREA COVERED BY THE DIFFUSION OF RADIOACTIVE CLOUDS

摘要

Estimation of radiation dose to the people surrounding a radiation control area due to the diffusion of radioactive clouds of gas or particles discharged from reactors or other high radioactive facilities in a nuclear accident or under normal operation conditions, seems to have a great Importance in considering geographical conditions and designating a radiation control area, even though such an estimation may be a rough approximation because correct estimation would be difficult owing to complicated circumstantial conditions.
