Strontium-90 in fish from the lakes of the Chernobyl Exclusion Zone

Frequency of dicentrics and contamination levels in Ukrainian children and adolescents from areas near Chernobyl 20 years after the nuclear plant accident

“…Th is could be one possible cause-eff ect explanation of a frequency higher than the basal one. Actually, radionuclide contamination has been reported in the last years in this area, which is referenced in the literature in fi sh (Kaglyan et al 2009) and water (Yablokov et al 2009), although the value (0.0020) here obtained is consistent with the basal superior limit (0.0010) considering the standard deviation (0.0014) of the measurement. Hence, it was not considered worthwhile to include in the results the estimated absorbed dose for those children who presented the highest value of frequency of dicentrics.…”

Transfer of 90Sr into fish in Finnish lakes

“…The 90 Sr activity concentration in whole fish was thus 1.5 times higher in perch than in pike and vendace, which had similar concentrations. Higher 90 Sr activities in perch than pike have also previously been reported for whole fish (Kaglyan et al, 2008;Beddington et al, 1989).…”

“…When the 90 Sr activity concentration was calculated in relation to the weight of calcium in ash, the highest levels were detected in non-predatory vendace (mean 2.2 Bq/g of Ca in ash), which were approximately twice as high as those measured in predatory pike and intermediate perch (mean 1.2-1.4 Bq/g of Ca in ash; Table 3). 90 Sr is known to accumulate in the scales, bones, fins and head, which are calcium-containing organs (Vanderploeg et al, 1975;Agnedal, 1966;Kaglyan et al, 2008). Saxé n and Koskelainen (2002) determined that the skin and fins contained from 70 to 85% of the total content of 90 Sr in fish, followed by 13-28% in the bones, although 90 Sr accumulation was highest in the bones.…”

The contents of artificial and natural radionuclides in tissues of the Percidae fish from the Dnipro Reservoir

“…Cesium-137 can be evenly distributed in organs and tissues, making it possible to estimate the radiation load in fish when penetrating the inside of radioisotopes. Strontium-90 refers to radionuclides with an osteotropic type of distribution is tissues (Kaglyan et al, 2009). As seen in table 1, the highest 137 Cs values in common perch specimens from the Samara Bay were recorded in the bone tissue -8.90±0.89 Bq/kg.…”

“…The radio-chemical load on water ecosystems has become more aggressive over the past 30 years due to anthropogenic disasters (Kaglyan et al, 2009;Romanenko et al, 2008Romanenko et al, , 2011Zarubin et al, 2013). The accident at the Chernobyl nuclear power plant in 1986 with the explosion at the Fukushima-1 nuclear power plant in Japan in 2011 caused a problem that affects the entire global community.…”
