General Description of the Research Project

Enhance monitoring for understanding changes in the dynamics of radionuclides that may be caused by recent environmental changes
The Exclusion Zone surrounding Chernobyl Nuclear Power Station is contaminated by radiocesium and various other radioactive materials, which are still having a devastating impact even 31 years since the accident. The water level of the Chernobyl Cooling Pond is diminishing till 6 m lower level since the circulation pump has been stopped in 2014, that will provide changes in the water environment and surrounding ecosystem. In addition, there is concern that the frequent occurrence of forest fires will also have an impact on the transport of radioactive materials. The project aims to support the enhancement of monitoring and prediction of the environmental dynamics of radionuclides by taking the above-mentioned factors into account.

Strengthening the management of the Exclusion Zone through enhanced monitoring and model predictions
Recently, the Ukrainian Government provides the efforts to restructure the Chernobyl Exclusion Zone with the aim of more effective land utilization rather than the resettling of refugees, since radioactive nuclides with a far longer lifetime than cesium -137* exist in this area. Land use purposes under consideration include waste management, operation of solar panels and designation as a wildlife reserve to protect the wild animals that have increased in population. It is expected that the findings of this project, such as environmental dynamics of radionuclides materials and estimated exposure to radiation of workers that enter this area, will be useful in facilitating the effective management of the Exclusion Zone.
*Cesium -137: A radionuclide with a mass number of 137. Its half-life period is estimated to be about 30 years.
