Sažetak
The 26th of April 2022 marks the 36th anniversary of the accident at the Chernobyl NPP. It is known for being the worst nuclear accident in history and was a radioecological catastrophe in Europe, the consequences of which are still being felt today. After the Chernobyl accident, a large amount of biohazardous radionuclides were released into the environment. The most biohazardous of which was Cs-137 (T1/2 30y), bioaccumulates and biomagnifies in marine organisms (B1/2 70d). While the upper permissible limit of Cs-137 activity concentration is 1000 Bq/kg for food and water, long-term monitoring indicated that activity concentrations were significantly lower and oftentimes below the detection limit (<0.3 Bq/kg). Furthermore, total Cs-137 dose rates were much lower than the IAEA proposed threshold value of 400 µGy/h (<0.001µGy/h). However, considering the relatively small size of Chernobyl compared to far larger reactor complex currently in the Ukraine war zone Zaporizhzhia (Zaporizhzya Nuclear Power Plant (ZNPP), the risk of radionuclide release into the environment remains at a high level. Such a scenario indicates the continued importance of monitoring the state of radioactivity in environment to enable assessment of any increased quantities of fission radionuclides entering the marine environment and eventually their biological damage.
