“…A dose of 1 mGy/day causes the first observable negative changes: the immune system is affected. A dose of 5 to 10 mGy/day negatively affects reproduction, and a dose over 10 mGy/day reduces lifespan in adult fish [10,11]. However, these effects are chronic in nature, and the dose rates in question are much higher than those resulting from the Fukushima accident.…”

Impact of the Great East Japan Earthquake on Reproductive Biology of the Freshwater Teleost Bluegill Lepomis macrochirus

Soon after the Great East Japan Earthquake and the subsequent accident at the Fukushima Daiichi nuclear power plant, we studied the reproductive biology of freshwater teleost bluegill (Lepomis macrochirus) in a pond in the city of Iwaki, Fukushima Prefecture, about 50 km south of the nuclear power plant. The breeding period of the bluegill was abbreviated and the frequency of spawning decreased. The radiation air dose rate and level of radioactivity in the fish were less than would be expected to trigger behavioural alterations or to suppress reproduction. The occurrence of aftershocks and two episodes of torrential rain is the likely reason for changes in the reproductive behaviour of bluegill in the pond. These results suggest that our observations can be explained by a combination of natural disasters, rather than the effects of nuclear radiation.

“…The typical dose rates of natural background exposure for different types of organisms in the Arctic are discussed by [3]. These dose rates have been derived using data on the activity concentrations of natural radionuclides in the Arctic aquatic ecosystems for several reference organism groups.…”

“…As a result, radiation effects may not appear during the winter period, and manifest themselves intensively during the warm season. High concentrations of lipids in the Arctic animals may be expected to increase the radiosensitivity, since chemical products of lipidoperoxidation produced by irradiation are toxic for organisms [3].…”

“…There is evidence to suggest that the in situ physical conditions in the Arctic may hypothetically alter radionuclide transfer to biota [2], at least in the case of poikilotherms. The modifying influence of Arctic climatic conditions upon the expression of radiation induced effects has also been hypothesised by [3]. Furthermore, low temperatures, extreme seasonal variations in incoming solar radiation and lack of nutrients are physical and chemical environmental stressors of Arctic organisms which limit biodiversity.…”

Abstract. The Arctic environment is unique in terms of many factors that may influence the behaviour and fate of contaminants including the presence of permafrost, low temperatures, slow breakdown of organic compounds, short food chains and long recovery times for some species. This study introduces the issues surrounding the development of a bespoke environmental impact assessment methodology specifically for the consideration of radiation impacts on Arctic ecosystems. The approach allows for the impact on plants and animals from exposure to radiation to be quantified in a robust manner through integration of our current knowledge concerning transfer in the environment, resultant dose-rates from the presence of radioactivity within biota and their media and information concerning radiobiological effects on endpoints of concern from an environmental protection perspective.

“…The EPIC database includes Russian/FSU (Former Soviet Union) data, which are based on information from publications in Russian. The database is focused on the effects of chronic/lifetime radiation exposure; this information is of great importance for the purpose of establishing the permissible dose limits to biota [1][2][3]. This paper is focused on the part of the EPIC database, which is related to the studies of effects of ionizing radiation on the survival and development of fish eggs.…”

Abstract.In the radiobiological studies of aquatic organisms, fish eggs are a favorite subject for experimental work because of easy availability of embryos and the possibility of observing the development of embryos within eggs. Data from Russian/FSU publications concerning the effects of ionizing radiation on the survival and development of fish eggs were compiled within the framework of the EC Project EPIC "Environmental Protection from Ionizing Contaminants in the Arctic" (2000)(2001)(2002)(2003). Comparative analysis was performed for effects on roe of two representative fish species: cold-water fish salmon (Salmo salar), and pike (Esox lucius), which is widespread predatory fish from the temperate climatic zone.
