Keywords: IODINE DEFICIENCY, IODINE-DEFICIENCY CONDITIONS,   PREVENTION OF IODINE DEFICIENCY,   IODIZED SALT

Abstract:  Iodine deficiency conditions (IDCs) refer to all pathological conditions developing in the population due to iodine deficiency that can be prevented by normalization of iodine intake. The spectrum of IDCs, along with thyroid pathologies, includes a number of gynecological, obstetric and neurological disorders. The most severe conditions related to iodine deficiency are associated with intrauterine impairments of the development of the central nervous system of the fetus. Epidemiological research conducted by the Endocrinological Scientific Center of the Russian Academy of Sciences demonstrated that in the Russian Federation there are no regions where the population would not be running the risk of developing IDCs. Solution of the problem of iodine deficiency conditions is simple and very effective from both economic and medical perspectives. Preventive measures are aimed at attainment of the optimal level of iodine intake by the population, which is achieved by mass iodine prophylaxis using iodized salt, intake of iodine-enriched foods, and both the group or individual iodine prophylaxis using pharmacological iodine preparations

Reference: Journal  “РАДИАЦИЯ И РИСК“ No.7 1996

Keywords: external and internal exposure

Abstract:  The paper presents results of ten-years field studies of levels and features of external and internal exposure doses for the population of Bryansk, Tula and Oryol regions of Russia affected by the radioactive contamination after the Chernobyl accident. Consideration is given to radio-ecological processes of migration of 131I, 134Cs, 137Cs, 89Sr and 90Sr in the biosphere, their intake and changes in human body for the residents of the contaminated areas with different soil conditions and extent of radiation protection. A model has been developed to account for external exposure of the public to γ-radiation of radionuclides occurring in the environment. The model has been verified against mass-scale measurements of individual absorbed doses by the thermoluminescence method. The paper also dwells on the models for intake of iodine, cesium and strontium radionuclides in human body which have been verified against mass-scale measurements with whole body counter and 90Sr in the section material. Examples are given showing exposure of residents of Russia in 1986 – 1994 and later. The collective dose from thyroid exposure to incorporated 131I in Russia and expected cancer thyroid morbidity has been assessed.

Reference: Patent, 01.12.2009 patent holder: State enterprise scientific-research centre of technology named after A.P. Aleksandrov

Keywords: liquid waste, cementing

Abstract: The invention relates to treatment of liquid radioactive waste. In a container, with non-radioactive cement compound, which plays the role of radiation shield, a filter with selective sorbent is installed. After establishing the resource of the filter, which is not aimed to be regenerated, with protection (filter-container) on disposal through the filter with selective sorbents, a thin Portland-cement slurry, with water cement ration not less than 10 percent, is pumped for cementing the monolith of the exhausted sorbent.

Abstract:  The Chernobyl Forum (September, 2005) concluded that in 20 years after the Chernobyl accident along with reduction of radiation levels and accumulation of humanitarian consequences severe social and economic depression of the affected regions and associated serious psychological problems became the most significant problems. The majority of the 600000 emergency and recovery operation workers and five million residents of the contaminated areas in Belarus, Russia and Ukraine received relatively minor radiation doses which are comparable with the natural levels. An exception is a cohort of several hundred emergency and recovery operation workers who received high radiation doses, of whom 28 died in 1986 due to acute radiation sickness and it consequences. Except dramatic increase in thyroid cancer morbidity in those exposed to radioiodine in their childhood and some increase in leukaemia and solid cancer morbidity among emergency and recovery operation workers with high radiation dose no evident growth of radiation-associated cancer diseases and leukaemia was detected in other groups of population. Radiation levels in the environment have reduced by a factor of several hundred since 1986, this ensures that the majority of the previously contaminated land in now safe for life and economic activities. Despite unprecedented scale and character of the Chernobyl accident its consequences for health and life of the affected population are significantly less compared with A-bombing in Hiroshima and Nagasaki. Findings of research of consequences of the Chernobyl accident made invaluable contribution to the development of nuclear technology and safety, radioecology, radiation medicine, radiological protection and social sciences. The Chernobyl accident initiated development of the global nuclear safety and radiation protection regime.

ISSN: 0025-8334

Keywords:     IODINE ISOTOPES (132- 135I ),  RADIATION ACCIDENT,  INHALATION,  THYROID,  ABSORBED DOZE,  IODINE DEFICIENCY

Abstract:  Purpose: The assessment of peculiarities of accumulation and distribution of 132- 135I absorbed doses in thyroid and their biological danger in case of radiation accident. Results: In case of radiation accident, the initial radiation danger is determined by iodine isotopes of 132- 135I inhaled as agaseous aerosol mixture. Inhalation intake of iodine radioisotopes is most dangerous for newborn and children below 1 year age, because of the differences in the breath rate and thyroid weight. High energy beta radiation emitted by 132- 135I isotopes in thyroid is absorbed more homogeneously if compared to 131I beta radiation, which results to the irradiation of both follicles and parenchyma tissue, blood vessels and neural terminals and causes the development of both stochastic and deterministic effects. The biological efficiency of inhaled short lived 132- 135I isotopes is approximately 10 times higher, than 131I efficiency and is comparable or even higher than the biological efficiency of the external gamma radiation.
