Ph.D. in Engineering from Graduate School of Engineering, Osaka University.
My specialty is radiation measurement. In particular, I am studying the technology of visualization of radiation distribution and the factors that affect environmental radiation due to natural phenomena such as lightning activity.
Main Focus of Research
- Development research on visualization technology of radiation distribution
- Integrated research of radiation and position recognition technology
- Measurement analysis of behavior of radioactive substances using natural nuclides
- Clarification of behavior of high-energy radiation generated by thunderstorm/ lightning activity.
Fields of Research
Radiation measurement, environmental radiation, atmospheric electricity
Radiation imaging, inverse problem analysis, atmospheric radon, energetic radiation, relativistic runaway breakdown

I have been studying radiation measurement and radiation physics in the environment.
After the Fukushima Daiichi Nuclear Power Station (FDNPS) accident, I have been conducting research and development on aerial monitoring that measures the radiation distribution in Japan using helicopters and remote monitoring technology by unmanned helicopters, mainly in Fukushima Prefecture.
Recently, I have been conducting research for the purpose of three-dimensional imaging using Compton cameras in order to visualize the radiation distribution in the high dose-rate field inside the FDNPS.
I’m also conducting research on the generation behavior of high-energy radiation in the atmosphere caused by lightning discharges and thundercloud electric fields.
A few words
So far, I have explained about environmental radiation in various places through field measurements. After March 11, 2011, through airborne survey, I recognized the importance of promptly measuring and announcing the distribution of radioactive substances released into the environment due to the FDNPS accident. From now on, by visualizing the distribution of radiation, I will also carry out activities to disseminate it to society using various media so that people can feel nature and science and technology that are difficult to see directly, such as ionizing radiation.
