Autor: Jun Hu, Yasunori Igarashi, Shunji Kotsuki, Ziping Yang, Mykola Talerko, Volodymyr Landin, Olha Tyshchenko, Mark Zheleznyak, Valentyn Protsak, Serhii Kirieiev

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-6 (2023)

Abstract The wildfires in the Chornobyl Exclusion Zone (ChEZ) have caused widespread public concern about the potential risk of radiation exposure from radionuclides resuspended and redistributed due to the fires in 2020. The wildfires were also conf

Reconstruction of the Long-Term Dynamics of Particulate Concentrations and Solid–Liquid Distribution of Radiocesium in Three Severely Contaminated Water Bodies of the Chernobyl Exclusion Zone Based on Current Depth Distribution in Bottom Sediments

Autor: Alexei Konoplev, Gennady Laptev, Yasunori Igarashi, Hrigoryi Derkach, Valentin Protsak, Hlib Lisovyi, Kyrylo Korychenskyi, Serhii Kirieiev, Dmitry Samoilov, Kenji Nanba

Publikováno v: Land, Vol 11, Iss 1, p 29 (2021)

Given the importance of understanding long-term dynamics of radionuclides in the environment in general, and major gaps in the knowledge of 137Cs particulate forms in Chernobyl exclusion zone water bodies, three heavily contaminated water bodies (Lak

Riverine 137Cs dynamics and remoralization in coastal waters during high flow events

Autor: Yoshifumi Wakiyama, Hyoe Takata, Keisuke Taniguchi, Takuya Niida, Yasunori Igarashi, Alexei Konoplev

Understanding riverine 137Cs dynamics during high-flow events is crucial for improving predictability of 137Cs transportation and relevant hydrological responses. It is frequently documented that the majority of 137Cs is exported during high-flow eve

A tuning-free wildfire detection algorithm reveals the impact of both Chornobyl wildfires and the Russian invasion of Ukraine in 2022

Autor: Jun Hu, Yasunori Igarashi, Shunji Kotsuki, Ziping Yang, Mykola Talerko, Volodymyr Landin, Olga Tischenko, Mark Zheleznyak, Valentyn Protsak, Serhii Kirieiev

The 2020 wildfires in the Chornobyl Exclusion Zone (ChEZ) have caused widespread public concern about the potential risk of radiation exposure from radionuclides resuspended and redistributed due to the fires. In this study, we developed a tuning-fre

Simulation study of radionuclide atmospheric transport after wildland fires in the Chernobyl Exclusion Zone in April 2020

Autor: Yasunori Igarashi, Olexandr Romanenko, Тatiana Lev, Ivan Коvalets, Mykola Таlerko

Publikováno v: Atmospheric Pollution Research. 12:193-204

This paper presents model results for the dispersion of radionuclides released into the atmosphere by intense forest fires in the Chernobyl Exclusion Zone in April 2020. The 137Cs activity concentration in the surface air is calculated on a regional

Vertical distribution of 137Cs in bottom sediments as representing the time changes of water contamination: Chernobyl and Fukushima

Autor: Aleksei Konoplev, Yoshifumi Wakiyama, Toshihiro Wada, Yasunori Igarashi, Gennady Laptev, Valentin Golosov, Maxim Ivanov, Mikhail Komissarov, Kenji Nanba

Bottom sediments of lakes and dam reservoirs can provide an insight into understanding the dynamics of 137Cs strongly bound to sediment particles. On this premise, a number of cores of bottom sediments were collected in deep parts of lakes Glubokoe,

Factors controlling the dissolved 137Cs seasonal fluctuations in the Abukuma River under the influence of the Fukushima Nuclear Power Plant accident

Autor: Yasunori Igarashi, Nanb Kenji, Toshihiro Wada, Yoshifumi Wakiyama, Yuichi Onda, Shota Moritaka

The 2011 Fukushima Daiichi Nuclear Power Plant (FDNPP) accident released large amounts of radioactive materials into the environment. River systems play an important role in the terrestrial redistribution of FDNPP-derived 137Cs in association with wa
