ICRP Publication 90. Biological effects after prenatal irradiation (embryo and fetus).

Reference: — Amsterdam: Elsevier (Pergamon), 2003. — 230 p.

Keywords: pre-implantation, organogenesis, and fetogenesis, animal study

Abstract: In its 1990 recommendations, the ICRP considered the radiation risks after exposure during prenatal development. This report is a critical review of new experimental animal data on biological effects and evaluations of human studies after prenatal radiation published since the 1990 recommendations.

Thus, the report discusses the effects after radiation exposure during pre-implantation, organogenesis, and fetogenesis. The aetiology of long-term effects on brain development is discussed, as well as evidence from studies in man on the effects of in-utero radiation exposure on neurological and mental processes. Animal studies of carcinogenic risk from in-utero radiation and the epidemiology of childhood cancer are discussed, and the carcinogenic risk to man from in-utero radiation is assessed. Open questions and needs for future research are elaborated.

The report reiterates that the mammalian embryo and fetus are highly radiosensitive. The nature and sensitivity of induced biological effects depend upon dose and developmental stage at irradiation. The various effects, as studied in experimental systems and in man, are discussed in detail. It is concluded that the findings in the report strengthen and supplement the 1990 recommendations of the ICRP.

Effects of different doses of ionizing radiation on the morphology of animal brain, under total exposure

Author: M.M. Aleksandrovskaya

Reference: 1959

Abstract: This writing is wide and well known among researchers, however, its details on the internet is not available. Presumably this work contains some data on the research of the Ural nuclear accident (1957).

Title: The physiological condition of the body and productive qualities of calves in ontogenesis under different environmental conditions and economic growth

Author: Korostelyov, Alexander

Reference: Bryansk, 2011

Keywords: ontogenesis, animals, bulls, ecology, genetics, physiology, productivity

Abstract: The main goal of the research – based on a thorough study of the influence of various density of radioactive contamination on the physiological function and productivity of the animals, to develop the concept of development of cattle breeding in the area of radioactive contamination and recommendations on technology of cultivation and feeding calves, in addition breeding cattle bulls of the black-and-white breed that ensures high productivity.

The Effects of Non-human Species Irradiation after the ChNPP Accident (English)

Reference: ScienceDirect, 2008

DOI: 574.415:539.1.04:[614.876:631.03958]

Keywords: soil, contamination, plants, animals, dose-effect relationship

Abstract: The area affected by the Chernobyl Nuclear Power Plant accident in 1986 has become a unique test site where long-term ecological and biological consequences of a drastic change in a range of environmental factors as well as trends and intensity of selection are studied in natural settings. The consequences of the Chernobyl accident for biota varied from an enhanced rate of mutagenesis to damage at the ecosystem level. The review comprehensively brings together key data of the long-term studies of biological effects in plants and animals inhabiting over 20 years the Chernobyl NPP zone. The severity of radiation effects was strongly dependent on the dose received in the early period after the accident. The most exposed phytocenoses and soil animals’ communities exhibited dose dependent alterations in the species composition and reduction in biological diversity. On the other hand, no decrease in numbers or taxonomic diversity of small mammals even in the most radioactive habitat was shown. In a majority of the studies, in both plant and animal populations from the Chernobyl zone, in the first years after the accident high increases in mutation rates were documented. In most cases the dose–effect relationships were nonlinear and the mutation rates per unit dose were higher at low doses and dose rates. In subsequent years a decline in the radiation background rate occurred faster than reduction in the mutation rate. Plant and animal populations have shown signs of adaptation to chronic exposure. In adaptation to the enhanced level of exposure an essential role of epigenetic mechanisms of gene expression regulation was shown. Based on the Chernobyl NPP accident studies, in the present review attempts were made to assess minimum doses at which ecological and biological effects were observed.

Radioecological investigation of food of animal origin in Belgrade environment.

Title: Radioecological investigation of food of animal origin in Belgrade environment.

Author: Gordana, Vitorović / Svetlana, Grdović / Branislava, Mitrović / Milan, Obradović / Branko, Petrujkić

Reference: The Japanese journal of veterinary research, 57 (3), p.169-173, Nov 2009

Keywords: food, animals, Belgrade, 137Cs

Abstract: The activity concentrations of 40K, 238U, 232Th and 137Cs were measured using gamma spectrometric method in different food chain samples from Serb Belgrade environment during the periods May-June 2007 and May-June 2008 year. Relatively high activities of 40K and 137Cs were detected in the soil. These results indicate that 137Cs is present in Belgrade environment even 20 years after nuclear accident in Chernobyl. However, in the samples of feedstuffs, animal products and bio indicators (meat of wild animals and fish), activity concentrations of primordial radionuclides and 137Cs were low and below the detection limits. Results of these trials have shown that investigated animal products from the natural environment around Belgrade, are radioactivity safe.

Abstract: Several United Nations organizations sought to dispel the uncertainties and controversy that still exist concerning the effects of the Chernobyl accident. A Chernobyl Forum of international expertise was established to reach consensus on the environmental consequences and health effects attributable to radiation exposure arising from the accident. This review is a synopsis of the subgroup that examined the radiological effects to nonhuman biota within the 30-km Exclusion Zone.
