In 2014 the decommission of Chernobyl Nuclear Power Plant Cooling Pond was started. As a result of the Cooling Pond water level has been declined the process of gradual transformation of the water ecosystem into the wetland is carried out. There is no analogy of the planned decommission of Cooling Pond with high-level of radionuclide contamination. The aim of this research is to investigate the combined effect of Cooling Pond water descents with ionizing radiation on the species diversity of newly-formed natural populations of small mammals. We started our research in autumn 2018. Abundance of animals in all polygons was grow to the highest level to autumn 2019. Number of species at the polygons and biodiversity level was grow up. But in 2020 we found that the Number of species and biodiversity level was sharp drop, while abundance of animals was at the same stable level.

チェルノブイリ原子力発電所の冷却池の排水床からの放射線生態学的ネズミ齧歯動物の研究

2014年、チェルノブイリ原子力発電所の冷却池の廃止措置が開始された。冷却池の水位が低下した結果、水の生態系が徐々に湿地帯へと転換するプロセスが発生している。高レベルの放射性核種で汚染された冷却池の廃止措置計画は他に類似するものがない。本研究の目的は、新たに形成された小型哺乳類の自然個体群の種の多様性に及ぼす、電離放射線と冷却池の水の沈降の複合効果を調査することである。我々は2018年秋に研究を開始した。全てのポリゴンにおける動物の豊かさは2019年秋までに最高レベルに成長した。ポリゴンの種の数と生物多様性のレベルが成長していた。しかし、2020年には、動物の豊かさは同じ安定したレベルにあったが、種の数と生物多様性のレベルが急激に低下したことがわかった。
