Research Areas

We develop production technologies of radioisotopes (RIs) at RIKEN RI Beam Factory (RIBF) for application studies in the fields of physics, chemistry, biology, medicine, pharmaceutical and environmental sciences. In our group, the produced RIs are mainly used for nuclear and radiochemical studies. The purified RIs such as Zn-65 and Cd-109 are delivered to universities and institutes through Japan Radioisotope Association. We also develop new technologies of mass spectrometry for the trace-element analyses using accelerator technology and apply them to the scientific research fields such as cosmochemistry, environmental science, archaeology and so on. We also develop chemical materials for ECR ion sources of RIBF.
