Project summary

It is well-known, that the vigorous activity of Semipalatinsk Nuclear Weapon Test Site during 1949 - 1989 has caused a significant radioactive pollution of an environment, and local habitants have received additional doses of irradiation, it has essentially complicated the economic activity of the given region population.

The General Assembly of the United Nations issued a number of resolutions on the international cooperation and coordination on rehabilitation of the population and the environment, and also regarding assistance to economic development of Semipalatinsk region of Kazakhstan. One of the first recommended actions was performance of "a radiological estimation Semipalatinsk Test Site” (STS) for reception of objective representation on present situation.

One of the main problems is the definition of integrated dose loadings of the local population. In spite of the fact that a lot of various organizations have performed and are currently performing research on STS, the question about dose loadings of the population and on a degree of radiating risk remains open. This question becomes more complicated now due to increasing of economic activity of the local population. The movement of people and cattle close and even inside of STS territory is intensifying and this may result in an additional irradiation. Uncertainties and lack of data to this question very much complicates the economic development of the region.

During the performance of ISTC Project К-465.2 the specifying data have been obtained, indicating that the population adjoining to STS settlements, apparently, can be pided into subpopulations, one of which has the raised doses of irradiation. Presence of subpopulations with different dose loadings is essentially a new research finding aspect, earlier nobody from researchers of a radiological situation on STS marked. It is obvious, that this question demands special attention studying as this aspect dropped out of a field of view practically all researchers worked in this region, including Project К-465.2, thus, the problem of an estimation of radiating risk for this part of the population remains sharply actual.

Within the limits of the offered Project carrying out research on STS situation in perfect other foreshortening, than all the previous numerous research in this region, is planned. If earlier the basic attention was devoted to radioactive traces and the analysis of radionuclei content on these places, this proposal offers to concentrate the basic attention on studying of dose loadings distribution of the population and livestock representatives in most close to STS villages, where population, showing vital and economic activity and being engaged in a different sort of business, can intensively move independently or together with their cattle from a place to place, visiting also and the contaminated STS parts. The Project proposes to reveal presence and a relative share of subpopulations with increased radiation exposures, to analyze probable ways of such increased doses receiving and to offer measures on their elimination. All this will promote the development of economical activity in the region, clearing up the radiological situation and removing quite obvious anxiety of local populations concerned with this problem.

And last but not least - the data obtained can be used also for the development of consequences management plans in the event of nuclear incidents or terrorist attacks using improvised nuclear devices or dispersion of a radioactive materials – now a likely scenario for any country in the world.

The Project purpose:

To investigate the distribution of integrated dose loads among representatives of the population and agricultural animals in settlements adjoining to STS and to offer means of reducing radiation exposures that will allow lower the risks for the economic activities in the region and for the consumers of regionally manufactured products.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
