Trace Elements in Abiotic and Biotic Environments
Chernobyl accident it has risen to 7.8 Bq/L. In the following year, it decreased to
5.4  Bq/L, and by 1990, it decreased to 0.2  Bq/L. Similar rises, and subsequent
falls, were detected in several other foodstuffs, including mutton and lamb (Reilly
2002). The content of radioactive Cs isotopes in daily food rations, in different
regions of Poland, in 1987 and 1988, was 1.80 and 0.93 Bq/kg, respectively
(Skibniewska et al. 1993).
A survey on long-lived artificial radionuclides 137 Cs in vegetables in Finland,
carried out in 2009–2010, showed that traces of 137 Cs deposition are still seen in
vegetables. But it can be concluded that the committed effective dose from the
ingestion of 137 Cs in vegetables is very low and the radiation-induced health detriment caused by this radionuclide is most probably negligible (Kostiainen and
Turtainen 2013).
