Malignant tumors of the respiratory organs are the second most important cause 

 of death from malignant tumors among the region's population, and their percentage has 

 been constantly increasing. During the period from 1950 to 1990, mortality indices 

 increased (from 1.65% to 56.02% or by 34 times). The mortality level among men was 

 increased by 3.3 to 7.2 times higher than among women. 



Women's mortality has been increasing constantly also from malignant tumors of 

 the breast (from 2.4% to 14.2%). The highest increase occurred from 1959 to 1970 after 

 which the rate of increase was somewhat slower. 



Malignant timiors of the urogenital tract have a significant place in the structure 

 of mortality of women in the kray from malignant tumors (up to 25%). The period from 

 1950 to 1965 showed a sharp increase (by 3.4 times) in women's mortality from this 

 cause. In the last 20 years, however, mortality of working age women from this cause 

 has decreased substantially (from 38.3% to IG.7%). In the past 20 years, mortality of the 

 male population from malignant tumors of the urogenital tract also increased by 2.4 

 times (from 3.3 to 7.9%). 



The mortality level from hematologic neoplasms in the kray increased between 

 1969 to 1990 (from 4.87% to 8.68%). The mortality of men from this cause is higher 

 than that of women (by 1.2-1.7 times). 



The incidence of mortality from the diseases of the endocrine system also showed 

 a constant growth frend, which peaked in 1981-1985 and was followed by a slight 

 decrease. The mortality of women due to this cause is 1.5 - 2 times higher than that of 

 men. 



Analysis of indicative morbidity (malignant tumors, thyrotoxicosis, neonatal 

 morbidity) and mortality (from malignant tumors, infant mortality, stillbirth, and 

 congenital anomalies) shows with a high degree of probability that the radiation factor 

 had and continues to have a place in the contamination of this region. The investigation 

 shows a direct effect on the health of living generations as well as a delayed effect (a 

 combination of the direct effect of environmental contamination and the effect on 

 subsequent generations through the maternal generation, which was directly exposed to 

 the radiation. Although detrimental characteristics are eliminated from the population 

 (decreased birth rate, increased mortality), remote consequences of the radiation factor 

 may still be manifested in many subsequent generations. 



An in-depth study of the effects of radiation contamination on the health status of 

 the population is needed, using the data on the radiation load in the kray and socio- 

 hygienic cohort analysis, which would permit a sufficiently accurate determination of the 

 effect of radioactive contamination of the environment on the health of the population.
