Institute of Environmental Radioactivity (IER) regularly holds the IER seminar, in which the faculty members report on their research results, with the purpose of facilitating their research activities and communication. The 11th IER Seminar of FY2021 was held on March 16, and Associate Professor, HIRAO Shigekazu gave a presentation on his research activities. The seminar was attended by 12 researchers and graduate students, including online attendees.
In the presentation on Investigation of atmospheric radioactivity in Okuma, Prof. HIRAO explained that the atmospheric concentration of Cs-137 has shown a gradual decrease from 2013 to 2018 and has leveled off at a certain concentration. He also introduced that due to the decontamination activities near the observatory points that began in 2018, Cs-137 continues to be released from the ground and buildings into the atmosphere.
After the presentation, various questions and opinions were exchanged among participants.
