The radioactive contamination represents the most dangerous aspect of technogenic environmental contamination. First, it calls sharp excess of natural concentration of the radioactive corpuscles in natural components (water, air and soil). Secondly, harmful agency of superfluous bombarding radiation on an person organism which till now is not studied by a science in full measure complicates forecasting perspective affecting of a radioactive contamination for population health. Therefore, in conditions of everywhere observed decline of nation health, one of the important duties of the nature protection organizations and bodies of public health services is observation and the analysis of the radiation situation formed in concrete territory. A cartographical method for research of these problems solution finds increasingly more application. It allows presenting available information in the evident and compact aspect which is facilitating and speeding up an estimation process of current situation. Thus, mapping of territory radiation risk will help both the design research organizations and establishments of public health services to solve following problems:

-          The analysis of modern radiation situation in the given territory and forecasting of its further evolution;

-          Revealing of interconnection between a level of population oncological disease rate and a local radiation background from ionizing radiation technogenic sources;

- development of provisions on revealing and preventive maintenance of local residents oncological diseases.

Now the medical-ecological mapping laboratory (SGGA) conducts works on mapping radiation risk for the population of Novosibirsk area.

Adverse radiation situation is formed on Novosibirsk area territory due to radio ecological factors both natural, and a technogenic origin. Correlation determination of medical statistics mapped data about population oncological disease rate with data about the spatial extending natural and technogenic radio ecological factors on territory of area, allows estimating radiation risk for population health of various area regions. The optimal means of this purpose achievement is to create digital map series which is evidently represented the interconnection of radiation situation in area territory with disease of local population by separate classes of oncological disease. Now works on creation of maps series reflecting the maintenance of radium emanation in soil, and radiation risk of oncological disease induction from two factors are finished: for affecting radium emanation, and for conducting medical radiological procedures. Scale of maps is 1:1 000 000. Thematic contents for presentation of the most rational ways of cartographic representation have been used: quantitative background, cartograms and cartodiagram. They have allowed presenting the information in an evident and compact mode. The compiled maps enable to estimate effect of radiation on health of local population and to prove a complex of provisions on early diagnostic and preventive maintenance of oncological diseases among local residents.

A cartographical method of research in the solution of these problems finds increasingly more application. It allows presenting available information in the evident and compact aspect which is facilitating and speeding up process of an estimation of developed circumstances. Thus, mapping of radiation risk of territory will help both the design research organizations and establishments of public health services to solve following problems:

-          The analysis of modern radiation circumstances in the given territory and forecasting of its further evolution;

-          Revealing of interconnection between a level of oncological sickness rate of the population and a local radiation background from technogenic sources of an ionizing radiation;

-development of provisions on revealing and preventive maintenance of oncological diseases of local residents.

Now the SGGA laboratory of medical-ecological mapping conducts works on mapping radiation risk for the population of Novosibirsk area.

In territory of Novosibirsk area adverse radiation circumstances is formed due to radio ecological factors of both natural, and a technogenic origin. Determination of correlation of mapped data of medical statistics about oncological sickness rate of the population with data about the spatial extending natural and technogenic radio ecological factors on territory of area, allows estimating radiation risk for health of the population of various regions of area. The optimal means of achievement of this purpose is creation of series of the digital cards which are evidently representing interconnection of radiation circumstances in territory of area with sickness rate of local population by separate classes of oncological sicknesses. Now works on creation of series of cards reflecting the maintenance of radium emanation in soil, and radiation risk of oncological sickness induction from two factors are finished: From affecting radium emanation, and from conducting medical radiological procedures. Scale of cards 1:1 000 000. For presentation of the thematic contain the most rational ways of cartographical representation have been used: Quantitative background, cartograms and cartodiagram. They have allowed presenting the information in an evident and compact mode. The created cards enable to estimate effect of radiation on health of local population and to prove a complex of provisions on early diagnostic and preventive maintenance of oncological diseases among local residents.
