The lab uses accelerators and radiation to analyze trace elements and develop radiopharmaceuticals for PET.
AboutAbout the lab
Exploration and well-being with accelerators and radiation
The Watabe Lab conducts research on putting accelerators, radiation, and radioisotopes (RIs) to good use.
Its foundation is technology for measuring radiation and knowledge of how radiation behaves inside matter.
Using accelerators such as the cyclotron at Tohoku University, the lab works on PIXE analysis, which examines extremely small amounts of elements, and on methods for developing new radiopharmaceuticals used in PET scans.
The lab aims to “contribute to people’s health and to a safe, secure society through radiation science.”
Key terms
- Radioisotope (RI)
- An atom that emits radiation as it changes into a different atom
- PIXE
- An analytical method in which particles accelerated by an accelerator are directed at a sample, and the elements it contains are identified from the X-rays that are emitted
- PET
- Positron emission tomography. A method that uses a radiopharmaceutical as a marker to image how molecules are used in the body

Accelerators, radiation, and radioisotopes (RIs) are widely used in fields ranging from basic science to engineering, environmental science, and medicine. Based on technology for measuring radiation and knowledge of how radiation behaves in matter, the lab studies technologies that make effective use of them.
*Illustrative imageElemental analysis and drug development with accelerators
Using Tohoku University's cyclotron and Dynamitron, the lab works on advancing PIXE-based ultra-trace elemental analysis and applying it to environmental science, on methods for developing new radiopharmaceuticals for PET, and on nuclear fuel cycle and advanced nuclide separation technologies for the effective use of nuclear fuel materials and RIs.
*Illustrative imageLinking radiation protection and medical use
Research on radiation protection and research on using radiation in medicine to improve the quality of diagnosis and treatment are closely related, and together they have been recognized as the research field of radiation science. Building on studies of the interactions between radiation and matter from physical and chemical perspectives, the lab works on radiation science.
