Development of a new calculation system to estimate decontamination effects (The 12th International Conference on Radiation Shielding (ICRS-12) and the 17th Topical Meeting of the Radiation Protection and Shielding Division of ANS (RPSD-2012)) -- (Accident of Fukushima Nuclear Power Plant and Its Influence)

The Japanese government plans to conduct decontamination tasks in radioactively contaminated areas. For such a situation, we developed a system that evaluates radiation dose rates in a wide radioactively contaminated area by utilizing our radiation dose evaluation technology. We also applied this system to actual decontamination model project and confirmed that this system was capable of calculating predicted dose rate after decontamination with sufficient accuracy.
