Abstract: Purpose: The assessment of thyroid pathology incidence in later life after 1-131 exposure in childhood in population residing in the area affected by the operation of nuclear industry enterprise. Material and methods: 1,062 residents of Ozyorsk, the city near Mayak PA, the first nuclear industry enterprise in Russian Federation, were subjected to thyroid screening. The main studied group (707) has included individuals born in 1950-1953 in Ozyorsk or the ones who moved in Ozyorsk within the first two years since birth. The reference group (355) included Ozyorsk residents born elsewhere and moved in the city after 1967 when releases of iodine-131 were minimized. The developed screening procedure included the obvious clinical, ultrasound and biochemical examinations. Individuals with any thyroid abnormalities revealed were sent to additional examinations and to an endocrinologist who has diagnosed patients and prescribed therapy. Results: Total frequency of thyroid pathology was 28 % (difference between main and reference groups was insignificant). The structure of diseases was dominated by nodular goiter (65 %), followed by autoimmune thyroiditis (23 %), and diffuse goiter (9 %), benign and malignant tumors – 3 %. Analysis of separate thyroid diseases revealed statistically significant increase of nodular goiter incidence in main group, especially in females (sex- and heredity-adjusted relative risk (RR) of exposure was 2.1, confidence interval (CI) of 1.4-3.2). Large nodules (10 mm diameter and more) were found more frequently among members of the exposed group than these in the non-exposed group (RR = 2.67, CI = 1.2-5.94). Non-nodular forms of thyroid diseases in main group were more often complicated by hormonal disorders (hypothyroidism), and had a tendency toward greater expressed signs of autoimmune invasion (increased count of antibodies to the thyroidal per-oxidase). Conclusion: Exposure to I-131 in early childhood in cohort of Ozyorsk residents increases in two time the relative risk of nodular goiter development in followed life. Risk increase of large solitary nodules development in thyroid of I-131 exposed individuals was revealed. Non-nodular thyroid diseases occurred on persons in the main group were more often complicated with functional disorders.

Keywords: metallic waste, decontamination, melting
Abstract: The series of invention relates to the decontamination of metallic materials contaminated by radionuclides. The processing includes melting of the waste beneath the layer, above which there is an intensive recycling flow overheated in gaslift flow of slag. Thus the slag is separated from the melted metal.

Keywords: solid noncombustible surface, decontamination
Abstract: The method consists of: covering the surface layer with powdered exothermic mixture, its arson and removal of the burning radioactive products. The exothermic mixture has the following composition, wt.%: Calcium-silicon powder – 40-60, alkali metal nitrate – 2-5, industrial oil – 1-2, powder of aluminum-magnesium alloy – the rest. Results: increase of the security mode, decrease of labor intensity, increase of productivity.

Keywords: liquid waste, process, filtration
Abstract: The invention relates to environmental protection, in detail, to process of liquid radioactive wastes. The original flow of the liquid waste is subjected to be defended by the formation of supernatant liquid and sludge. The supernatant fluid is clarified with a mechanical filter to form a filtrate; the filtrate is subjected to ion-selective sorption after deep desalting in two stages.

Keywords: Leukemia
Abstract: The work focuses on direct epidemiological assessment of radiation risks in induction of leukemia and thyroid cancer in emergency workers after the Chernobyl accident. The Russian National Medical Dosimetric Registry compiles data for 168 thousand emergency workers as of 01.01.1996. Analysis is performed of 48 leukemias and 47 thyroid cancers diagnosed and verified in emergency workers. The estimated radiation risks are: for leukemia – excess relative risk per Gy (ERR/Gy) is 4,30 (95% CI = 0,83; 7,75), excess absolute risk per 104 PY Gy (EAR/104 PY Gy) is 1,31 (95% CI = 0,23; 2,39); and for thyroid cancer – ERR/Gy is 5,31 (95% CI = 0,04; 10,58), EAR/104 PY Gy is 1,15 (95% CI = 0,08; 2,22).

Abstract: Continuous rise in thyroid cancer morbidity is the most important problem of the post-Chernobyl period. We analyzed clinical features of 1185 patients who were above 18 years of age when the Chernobyl atomic station catastrophe occurred. The post-Chernobyl thyroid cancer is characterized by a higher rate of multicentric growth with specific clinical symptoms. The first sign of thyroid cancer with multicentric growth in adults is a set of symptoms including weakness, decreased abilities, fatigue, somnolence (56.5% of cases). Thyroid cancer is often associated with myoma of the womb (23.6%). The active detection strategy resulted in a dramatic rise in early thyroid cancer (pT1-2N0M0) in the region of Bryansk (86.1%) thus providing a basis for better treatment outcomes.
