Grundsätzlich sind alle Tiere gegenüber radioaktiver Strahlung empfindlich, da diese eine direkt schädigende Wirkung auf die Zelle als kleinster biologischer Einheit haben und zelluläre Bestandteile und hier insbesondere die zelluläre Erbsubstanz (DNS) verändern oder zerstören kann (vgl. "Vertiefende Ausführungen" unter "Wirkfaktoren").

"Liver and muscle tissue from dead seals and porpoises found stranded around the UK coast have been analysed for the following radionuclides: 134Cs, 137Cs, 238Pu, 239Puq240Pu. Multifactor analysis of variance indicated that, for radiocaesium, there was no significant difference for harbour seals, grey seals or porpoises in terms of species or gender; however, the tissue activity concentration increased with body weight and decreased with distance from Sellafield, the major nuclear reprocessing plant in the UK. [...] The marine mammals concentrated radiocaesium from their environment by a factor of 300 relative to the concentration in seawater indicating the value of using marine mammal tissue to measure radiocaesium contamination in the marine environment. The maximum radiation dose to the marine mammals from radiocaesium was higher than doses previously assessed for critical groups of humans living near Sellafield, while the maximum dose from plutonium was comparable to the doses for humans."

"Accumulation was found to be species specific in the two seal species studied, with 9 times higher activity concentration in grey seals compared to herring, and 3.5 times higher in ringed seals compared to herring. We discuss potential paths and rates of bioaccumulation of radioactive caesium in the Baltic Sea including species specific prey choice of the two seal species and estimate life time exposure."
