According to Polikarpov’s conceptual model of ecological zones,
radioecological effects of chronic ionizing radiation dose rate levels from alpharadiation of
239,240 Pu for the Black Sea hydrobionts are specific for the “Well-being
zone” and “Uncertainty zone” (Tereshchenko and Polikarpov 2007; Tereshchenko
et al. 2014) and in the ChNPP 30–km zone the dose rates from man–made
radionuclides were significant higher and reached the “Physiological masking
zone”, the “Ecological masking zone, ”and even the “Zone of damage to ecosystems” (Fig. 16.9).

Concentration Activity in Seawater
Staying on for hundreds of years, by a recorded environmental radiation factor that
creates chronic radiation exposure on marine life, contemporary content of plutonium in the Black Sea does not have a damaging effect on biological components of
the sea ecosystem. But radioecologycal situation can be changed. So, based on field
observations and model calculations as well as on the conceptual model of chronic
action zonality of ionizing radiations dose rates in the nature (Polikarpov 1998;
