ABSTRACT
The study was performed with the help of a questionnaire of views of senior schoolchildren about the objectivity and stressfulness of various forms of the control of knowledge, the level of stress in the exams and measures for its reduction. 53.4% out of the students assess their knowledge in this area as insufficient. The most objective form of the control students consider an oral exam, the least stressful--blank testing. After passing the exams in class 9 we observed the evident reduction of representations of the objectivity of test forms of control. The necessity of the activization of educational work with students on the issues of prevention of exam stress and methodological work on perfection of the organization and content of the forms of Knowledge control is showed.

Environmental conditions in the area hosting a plant for processing and long storage of low- to moderately-active radioactive waste are described as reasonably safe. Residence in the area does not exert negative influence on the physical and mental development of children. Several indicators of physical development give better estimates than at the control territory. The difference can be accounted for by a better social situation in the study area (housing conditions, financial standing, food patterns, general lifestyle).

Operation of enterprise for radioactive waste processing and disposal does not influence negatively physical and mental development of children and adolescents residing in the area under observation. In some parameters, physical and mental development of children and adolescents residing in the area under observation surpasses that in reference area--that could be due to social and economic peculiarities.

Absence of early signs specific for thallium intoxication requires objective diagnostic methods. The studies covered 4 techniques: electroretinography (ERG), assessment of urine levels of thallium and delta-aminolevulinic acid, capillaroscopy. The authors supported their previous foundation concerning diagnostic value of ERG for early diagnosis of thallium effects (higher amplitude of b-wave in one and that of a-wave in 8 out of 10 examinees). Further experimental and clinical basis for grading the intoxication through amounts of urinary thallium were found promising. Capillaroscopy method appeared informative: 8 out of 12 examinees demonstrated spastic and atonic state of hand capillaries--that provided objective verification of vascular disorders in workers exposed to thallium and its derivatives.
