Keywords : chronic exposure, hemopoiesis, immunity, endocrine system, gonads, skin, lungs

Abstract: Reviewed are radiobiological data on the emergence of tissue reactions that may determine the course and outcome of human chronic irradiation. The main mechanisms of the reaction of hemopoietic, immune, reproductive, endocrine, respiratory systems and skin to long-term and fractionated exposure to ionizing radiation are considered. The problem of developing a new approach to threshold dose estimation for chronic exposure effects is discussed.

Keywords:EEG patterns, children, mothers, WISC

Abstract: One hundred children, exposed prenatally to radiation after the Chernobyl nuclear power plant accident, and 50 non-exposed classmates were examined between the ages of 11 and 13 years old using neuropsychiatric tests, WISC, EEG, and visual evoked potentials. Individual prenatal radiation doses were reconstructed for all examined children. The exposed children were found to have more neuropsychiatric disorders, left-brain neurological signs, lower full-scale and verbal IQ, IQ discrepancies with verbal decrement, disorganized EEG patterns, an excess of lateralized-to-left frontotemporal region delta and beta power with depression of theta and alpha power, and interhemispheric inversion visual information processing. Mothers’ mental health, stress, and prenatal irradiation contributed to these effects, along with several confounding factors. (full text in English available on web.)

Keywords: migration of radionuclides, effects on biota, ecosystem, public exposure

Abstract: Describes the basic system of migration of radionuclides in the environment, assessing the scale of effects of radiation on the biota. Evaluates the significance of the consequences of radioactive contamination on natural ecosystems in terms of the formation of public exposure.

The intellectual development, mental and behavioural disorders in children from Belarus exposed in utero following the Chernobyl accident

Title: The intellectual development, mental and behavioural disorders in children from Belarus exposed in utero following the Chernobyl accident

Author: Igumnov, S / Drozdovitch, V

Reference: European Psychiatry, 15 (4), p.244-253, Jun 2000

doi: 10.1016/S0924-9338(00)00237-6

Keywords: education; emotional disorder; exposure; prenatal; social factors; specific learning ; thyroid dose

Abstract: The study examined psychological development in 250 children at the age of 6–7 and 10–12 years who had been exposed in the prenatal period at the time of the Chernobyl accident in 1986. These children were compared to a control group of 250 children of the same age from non- and slightly contaminated areas of Belarus. The examination included psychiatric examination and intellectual assessment as well as the estimation of thyroid exposure in utero. The mean value of thyroid doses from ¹³¹I 0.39 Gy was estimated for the prenatal exposed children….
