Description

Automatic translation: A quantitative assessment of the values of the accumulation of radionuclides for freshwater reservoirs makes it possible to predict their concentrations in aquatic organisms, as well as radioecological risks and risks of radionuclide entry into the human body through food chains. It is customary to describe the accumulation of a radionuclide by aquatic organisms by the equilibrium ratio of the concentration (CR) of the radionuclide in the body to the concentration in the environment. It should be noted that CR are not universal characteristics of each species of aquatic organisms and can vary significantly depending on various environmental factors or characteristics of the organism. Extensive literature is devoted to studies of concentration ratios, including studies of water bodies of the Chernobyl Exclusion Zone (ChEZ).

Abstract (Russian)

Количественная оценка значений накопления радионуклидов для пресноводных водоемов даёт возможность прогнозировать их концентрации в гидробионтах, а также радиоэкологические риски и риски поступления радионуклида в организм человека по пищевым цепочкам. Аккумуляцию радионуклида гидробионтами принято описывать равновесным отношением концентраций (CR) радионуклида в организме к концентрации в среде обитания. Следует отметить, что CR не являются универсальными характеристиками каждого вида гидробионтов и могут существенно меняться в зависимости от различных факторов внешней среды либо особенностей организма. Исследованиям отношений концентраций посвящена обширная литература, включая исследования водоемов Чернобыльской зоны отчуждения (ЧЗО).
