that it is quite normal and it is in their standgtrds but alongside 

 the data that was — but at the same time the results of their sci- 

 entific research show that the radioactive pollution of air, water 

 and soil, fish and animals in some places in Siberia was quite sig- 

 nificant. 



There are several reasons for that radioactive pollution. Thus, for 

 example, the first reason is the nature of gamma radiation due to 

 the open deposits of ancient crystals and radioactive minerals and 

 usage of radon and other natural construction materials. The sec- 

 ond reason is a global radioactive pollution because of the nuclear 

 weapons on Novaya Zemlya and in Semipalatinsk, in China, and 

 after the nuclear explosion in Chernobyl nuclear power station. 



The third reason is technical radioactive pollution as a result of 

 radioisotopes used in medicine, extraction of the radioactive mate- 

 rials, geological exploration in Noralt (ph), gold and tin extraction, 

 underground nuclear explosions in Yakutsk Republic, and during 

 the period of 1974 to 1987 12 underground nuclear explosions were 

 made on the territorial republic. The fourth and the last reason is 

 dangerous radioactive technology, like automatic meteorological 

 stations working on the basis of isotopes and some industrial enter- 

 prises in Novosibirsk, Krasnoyarsk, Tomsk. 



The analysis indicating the rates of people's death was made in 

 some regions of Siberia. The people's deaths of cancer, thyroid toxi- 

 cosis, infant death are important indicators of the increasing eco- 

 logical pollution on the territory. I would like to give you several 

 examples. 



Chukotka. Cancer takes the second place among the reasons of 

 the people's death on the territory of this region. In 1970 10.3 per- 

 cent of death were caused by cancer, and in 1988 the percentage 

 increased and it was 26,9 percent. Infant death, because of the can- 

 cer, is two times higher among the native population. Especially 

 high is the level of death because of Ivmg cancer. 



The City of Tomsk. The level of cancer was increased by 2.5 

 times from 1976. And scientific research made in space showed 

 that the highest level of oncological disease occur in their industrial 

 regions with the highest level of pollution. 



In Magadan the level of their air pollution increased by 2.5 times 

 and their oncological diseases increased for the last 10 years by 

 42.4 percent and death caused by the cancer increased by 73 per- 

 cent. 



The Region of Altay. For the last 40 years the level of the 

 oncological diseases increased by five times and the level of their 

 lung cancer increased by 50 times. The people's death increased by 

 seven times and the infant death, because of the cancer, increased 

 by 18 times. 



Thus although the analysis of the reasons of all diseases shows 

 the bad ecological situation, we can speak about the leading role 

 of the radiation as the main cause of the oncological diseases. 



There £ire some other reasons, like significant pollution of air and 

 water, the change in the food, bacterial situation. That's why I 

 think it is very important to make a joint detailed scientific re- 

 search of the whole complex of the problems, including the influ- 

 ence of the radioactive situation in Siberia on the health of its pop- 

 ulation. And it is better to do within the fi*ames of the existing
