Content of Short-Lived Radionuclides (<sup>95</sup>Zr, <sup>95</sup>Nb, <sup>103</sup>Ru, and <sup>106</sup>Ru) in Fish
This review addresses the intake, distribution, and bioaccumulation of the short-lived radionuclides <sup>95</sup>Zr, <sup>95</sup>Nb, <sup>103</sup>Ru, and <sup>106</sup>Ru in aquatic ecosystems before and after the 1986 accident at the Chornobyl Nucl...

| description | This review addresses the intake, distribution, and bioaccumulation of the short-lived radionuclides <sup>95</sup>Zr, <sup>95</sup>Nb, <sup>103</sup>Ru, and <sup>106</sup>Ru in aquatic ecosystems before and after the 1986 accident at the Chornobyl Nuclear Power Plant. Particular attention is given to a detailed analysis of these processes in fish belonging to different ecological groups, as well as in their various organs and tissues. Observational data indicate that <sup>95</sup>Zr and <sup>95</sup>Nb predominantly accumulate in external organs, with comparatively lower concentrations observed in internal organs. In contrast, <sup>103</sup>Ru and <sup>106</sup>Ru exhibit higher bioavailability and a marked tendency to accumulate in internal tissues. A notable feature of <sup>106</sup>Ru is its gradual increase in muscle tissue over time following the accident. These findings are critical for advancing our understanding and assessment of the ecological status of contaminated aquatic environments, for predicting the long-term impacts of accidental radionuclide release, and for informing strategies related to environmental monitoring and the safe exploitation of aquatic biological resources. |
