Speaker (In order of presentation)

KAWAHARA Rika
Sam KOH
(Both are in the second year M.S. students, Major in Environmental Radioactivity)

Presentation Title

・Radiation distribution images by using Compton camera at Hamadori, Fukushima Prefecture(Kawahara)
・Feasibility Study on the Application of Monte Carlo Simulations to Airborne Radiological Survey for the Estimation of Atmospheric Radon and its Progenies(Koh)

Institute of Environmental Radioactivity (IER) regularly holds the IER seminar in which the faculty members report on their research results, with the aim of facilitating their research activities and promoting communication.

In the 5th IER seminar of this fiscal year that was held on October 24, 2022, two master’s students of the Major in Environmental Radioactivity made presentations on their research activities. They are going to have the final exam of master’s dissertation in the coming February and the seminar was a sort of interim presentation to report their progress for it.

Ms. Kawahara, who is working with Project Professor Torii on the visualization of radiation distribution using a Compton camera, presented the results of the measurement survey conducted in the difficult-to-return zone and the issues to be addressed.
Mr. Koh, who is working under the guidance of Associate Professor, Hirao, presented his basic research on estimating the concentration of atmospheric radon-222 and its progenies by using radiation data obtained by airborne monitoring surveys and optical transport calculations.

After their presentations, the faculty members asked questions and made comments, which seemed to be a good stimulus for the students to complete their master’s thesis.
