of the sex organs (from 3.3 to 7.9% of deaths). 



Mortality due to cancer of the blood increased -in the region 

 from 1959 through 1990 (from 4.87% to 8.68%). increases in 

 mortality of men and women from blood cancer was similar (1.2-1.7 

 times) . 



Mortality of the population due to illness of the endocrine 

 system also showed a gradual tendency to increase with maximum 

 values in 1981-1985, followed by a decline. Mortality in women 

 from this cause was 1.5-2 times that of men. 



Analysis of the epidemiology data (malignancies, thyroid 

 Illnesses, illness in new borns) and mortality statistics (from 

 malignancies, mortality of youth, still births and birth 

 abnormalities) indicate the very high probability that 

 radioactive contamination of the region was factor. The research 

 material indicate that the effects on the health of residents was 

 direct and indirect (combination of direct influences from 

 environmental contamination and effects through the mother, 

 directly impacted by the radiation) . Although the harmful signs 

 are being eliminated from the population (decreased birth rate, 

 age of death) , there are possible long term effects of radiation 

 on future generations. 



In depth research on the influence of radiation on the 

 public health is necessary using data on the radiation load 

 (contamination levels) in the territory and social-hygenic 

 methods of cohort analysis, which would permit a more accurate 

 determination of the degree of influence of radioactive 

 contamination of the natural environment on the public health. 



In Novosibirsk high levels of cancer are observed in the 

 Maslyaninsk, Kochenevsk, Kolyvansk, Chistoozern and Kargatsk 

 regions, and also in Novosibirsk city itself (more than 250 cases 

 per 100 thousand inhabitants) . 



Mortality from lung cancer is highest (above 40.0 per 100 

 thousand inhabitants) in Chistoocern, Ubinsk, Bagansk, 

 Kochenevsk, Yst'-Tarsk, Ordynsk, Moshkovsk, Toguchinsk, 

 Kolyvansk, Suzunsk, Maslyaninsk, Bolotninsk and Zdvinsk regions, 

 and also in Berdsk city. Low level (less than 30 per 100 

 thousand) were noted in Barabinsk, Vengerovsk, Dovolensk, 

 Kochovsk, Severn, Tatarsk and Chanovsk regions. The Moshkovsk 

 region fill out in the very bad group for health problems and 

 statistics confirmed the high significance of mortality from 

 stomach cancer in the mortality statistic from cancer. A similar 

 situation is present in the Kolyvansk region. Upon examination 

 of the statistics, Tatarsk was moved from the "high average" 

 category to the "bad" category, Ust'Tarksk and Bagansk from the 

 "low average" to "Bad" and Severn region from "good" to "low 

 average". 



A more accurate picture of the relationship between 

 environmental factors and cancer in the population of a region is 

 produced by a complex analysis of the four indicators (mortality 

 and illness from all classes of malignant pathologies, and also 

 mortality from lung and stomach cancer). In this case, 

 Chistoozern, Kochenevsk, Moshkovsk, Kolyvansk and Maslyaninsk 

 regions fill in the bad category. As the above analysis showed, 

 in the first two regions lung pathologies were primarily
