Distribution and Dynamics of Radionuclides in the Chernobyl Cooling Pond
As a result of the accident at the Chernobyl Nuclear Power Plant (ChNPP) in 1986, the Cooling Pond (CP) was heavily contaminated by radionuclides due to atmospheric fallout and discharges from the industrial site. Shortly afterward, most of the radionucli

Preface
The Chernobyl accident occurred on 26 April 1986 at 1:24 a.m. local time during the scheduled outage of the fourth unit reactor when the experiment on testing a turbine generator was being carried out (IAEA 1986). The experiment was to investigate reactor safety in the event of failure of the mains electricity supply to the plant. The test program, however, was not properly designed and concurred, with no additional safety measures stipulated and the emergency core cooling system switched off. The experiment led to a steam explosion which blew the lid of the reactor and resulted in the largest accidental release of radioactivity into the environment in the history of nuclear power production. The exposed reactor core continued to burn for approximately 10 days with continued releases of radioactivity into the atmosphere over this period (IAEA 1986; Alexakhin et al. 2001; Beresford et al. 2016). This was the worst nuclear disaster in history in terms of the amounts of released radioactive materials
