Estimation of radiation source distribution

Last updated on Dec 5, 2025

In response to accidents at nuclear facilities and terrorist attacks using radioactive materials, it is necessary to identify the distribution of radiation sources while limiting the risk of exposure to humans. We have developed a method to estimate the distribution of radiation sources using a mobile robot equipped with a radiation detector.
