“…3). Contrary to observations for radiocaesium (Hadderingh et al, 1997;Smith et al, 2002), there was no evidence of a clear ''size effect'' of increasing 90 Sr activity concentration with increasing fish weight. None of the relationships observed in Fig.…”

Empirical relations between the (90)Sr concentration factor (CF) and the calcium concentration in freshwater aquatic systems have previously been determined in studies based on data obtained prior to the Chernobyl accident. The purpose of the present research is to review and compare these models, and to test them against a database of post-Chernobyl measurements from rivers and lakes in Ukraine, Russia, Belarus and Finland. It was found that two independently developed models, based on pre-Chernobyl empirical data, are in close agreement with each other, and with empirical data. Testing of both models against new data obtained after the Chernobyl accident confirms the models' predictive ability. An investigation of the influence of fish size on (90)Sr accumulation showed no significant relationship, though the data set was somewhat limited.

“…The ''size effect,'' whereby larger (in terms of weight) fish have higher activity concentrations of radiocaesium, has been documented in both river and lake fish populations (Elliott et al, 1992;Hadderingh et al, 1997). This has been ascribed to differences in feeding habits, metabolism, excretion and the nonequilibrium in the fish-water system (Elliott et al, 1992;Ugedal et al, 1995;Hadderingh et al, 1997;Smith et al, 2005).…”

In Øvre Heimdalsvatn, there are some differences in feeding habits, habitat and growth rates between trout of different sizes ) that could explain the size effect.…”

“…Additional details are given in Gjerseth (2004). Ecological half-lives were estimated using the equation: T 1/2 (ecol) = t Á Ln2/Ln(N/N 0 ), where N 0 is the initial 137 Cs activity content and N is the activity content at time t. For most of the analyses log transformed activity concentrations of 137 Cs in trout between 200 and 300 g were used, as this material was normally distributed and to avoid the confounding size effect (Elliott et al, 1992;Hadderingh et al, 1997).…”

The Norwegian mountain lake, Øvre Heimdalsvatn, received major fallout from the Chernobyl accident in the spring of 1986. Activity concentrations of 137 Cs have been monitored annually in the brown trout (Salmo trutta) population of the lake over a 22-year period since 1986. The activity concentrations of 137 Cs in brown trout have declined over the period, although in recent years there has been little or no reduction in activity concentrations. Throughout the period, there has been considerable individual variation in 137 Cs activity concentrations. Within a single year, fish weight was the most significant factor affecting activity concentrations of 137 Cs in individual fish, although sex and ageÁweight were significant explanatory variables. The ''size effect'' was not significant during the initial period after fallout and in some recent years. During the first years after fallout, the ecological halflife of 137 Cs in brown trout was 3-4 years, but during the last decade this has increased significantly and has approached the physical half-life of 30 years for 137 Cs, suggesting a dynamic equilibrium between catchments inputs, possible remobilisation from lake sediments and lake outputs of 137 Cs.

“…In the long term, activity concentrations in predatory fish were significantly higher than non predatory fish and large fish tended to have higher activity concentrations than small. The increase in activity concentration in large fish is termed the "size effect" (Elliot et al 1992;Hadderingh et al 1997) and is due to metabolic and dietary differences. In addition, older, larger fish were exposed to higher levels of 137 Cs in the water than younger, smaller fish.…”

Recommendations for decontamination of the urban environment in case of large-scale radioactive contamination should be distributed to management of nuclear facilities having the potential of substantial accidental radioactive release (NPPs and reprocessing plants) and to authorities of adjacent regions. Research Generally, physical and chemical processes involved in environmental countermeasures and remediation technologies, both of mechanical nature (radionuclide removal, mixing with soil, etc.), chemical nature (soil liming, fertilisation, etc.) or their combinations, are understood well enough in order to be modeled and applied in similar circumstances worldwide. Much less understood are the biological processes that could be used in environmental remediation, e.g., re-profiling of agricultural production, bioremediation, etc. These processes require more research. An important issue that requires more sociological research is perception by the public of the introduction, performance and withdrawal of countermeasures in case of emergency, as well as development of social measures aiming at involvement of the public in these processes at all stages beginning with the decision making.
