[en] For checking undertaken decisions correctness of final reactor tests a carrying out into reactor underground reactor test stand (RUTS) is proposed. Such experiments allow an estimation of the safety of a new generation of reactor under conditions closely approaching real ones. The RUTS presents an adequate preliminary scale reactor model for a study of severe accidents. The RUTS will be placed into Degelen site's stores. The possibility of the extension of this work into other branches of nuclear power engineering is also considered

[en] The 'Prophylaxis' and 'Test site' comprehensive programmes are carried out for estimation of inhabitants health changes by both the Semipalatinsk test side influence and the significant technic genius pollution of environment called of industry development. It is defined, that Pavlodar region is object of radiation influence of Semipalatinsk test site. There are consequences of operation of industry enterprises (of power engineering, metallurgy, oil-chemistry) on large territory of the region. Aggravation of this region's population health was established during deepened study of sick rate with medical examination of more 12000 inhabitants and special onco-epidemical, cytological, medical genetic, immune researches. The character of chromosomal aberrations and oncological pathologies is testified about the essential influence of test site factors on health aggravation. System analysis shows, that low radiation doses are affected life quality and region population health

[en] One of immuno correctors under development of common adaptive syndrome is saps's mixture of the plantain and the burdock. Research of influence of saps's mixture of the plantain and the burdock on enzymes activity of energetic and purine exchange under stress was carried out. There were 2 series of experiments with 120 white rats. Results showed that the irradiated animals on the background phyto therapy had high enzymes activity under stress during all of the investigation periods. The preparations from plantain and burdock biomass increase unspecific resistivity of organism and helps of energetic exchange's rise irradiated organs's sells of animals under stress

[en] The purpose of this work is study of immune system peculiarity reaction on the radiation influence and helium-neon laser's (HNL) immuno-correction of irradiated organism. There were 3 series of experiments on white rats with mass 180±20 g. Animals in II and III series were irradiated by Co gamma-rays with dose 6 Gy. After 30 days animals of III serial were exposed to action of HNL during 5 days. Under HNL action the T-system of immunity functional activity has been normalized. The rise of unspecific resistivity of organism is marked

[en] The taktivin immune correction action on irradiated organism immune system is studied. There were two series of experiments with 50 animals in each serial. The intacted and irradiated animals served as control ones. Irradiated animals have got the taktivin course 1,5-2,0 μg each 1 kg of mass intraperitoneally, during 3 days. Under tactivin action the immunity's T-sells quality and quantitative ability has been increased, and the lymphoid cells in the bone morrow and thymus have been normalized, and its quantity in spleen and small intestine's lymph nodes have been rise. The activation of energetic exchange within spleen has being carried out

[en] A object of investigation is Semipalatinsk test site and its encirclement's radiation situation. The accessible materials on this problems are analysed. The summary of main characteristics of square investigations on Cs-137 is given. 1 tab

[en] The main problems of project are formulated in this paper. The problems are as follows: - Creation of certified analytical laboratories in Almaty and Kurchatov; - Creation set of Semipalatinsk test site's soils standard samples; - Definition of the Semipalatinsk test site's pollution levels on base of retrospective analysis and new data by radionuclides and toxic elements; - Study of existing forms of radionuclides and toxic elements and its associations with soil fractions's elementary structural composition; -Creation of central computer base of allowing for and data processing, and visualization of information in the chart form. 5 refs

[en] The investigations showed that separate kinds of Degelen mountain site's lichens are able existing under conditions of wide variability of radiation background. There are six kinds of lichens and in its exposure dose rate exceeds to 6-30 times (Diploschistes scrposus (Schreb.) Nyl, Parmeliopsis ambigua (Wulf) Nul, Parmelia stupea Tayl, P. scortea Ach, P. physodes Nyl, P. tinchina Mah. et Gill). The radiocesium contents study shows that more accumulation ability have Parmelia scortea (570 Bq/kg), Parmelia fraudans (620 Bq/kg), Parmelia cetrata (470 Bq/kg), Parmelia conpersa (340 Bq/kg). The cesium-137 in the lichens to 2-8 time exceeds of maximum permissible dose

[en] The drug N 52 which extracted from sweet-brier growing in the Semipalatinsk region is described in this work. For clarification of the radio-modifying factors of this drug the experiments have been carried out on males of white rats under different gamma-irradiation doses (6-8 Gy) with using of hospital, physiological and hematological control. It was defined that the drug shows itself in two ways by use of total gamma-irradiation: 1) it has radioprotection action under 7-8 Gy dose and 1/8 S D₁₆ concentration and 2) radiosensitization action under 1/2 S D₁₆. And radiosensitization effect has been risen with irradiation dose decrease

[en] The retrospective assessment of radiation doses on inhabitants of populated area of the Republic of Altaj was carried out by thermo luminescence of quartz inclusions in red brick with use pre-dose method . This method includes following processes: an extraction of crystalline quartz, measuring of sensitivity of sample before the thermo activation, a definition of optimal temperature of thermo activation, a sample radiation under calibration doses, a calculation of ceramics's accumulated dose (pre-dose) by the gain of sensitivity value. The 'Methodic of measuring of accumulated gamma-radiation dose in the structural ceramics by quartz thermo luminescence' was worked out on the base of this method. According of this methodic the radiation doses were measured in number of populated area of Altaj Republic
