Now nuclear tests are forbidden by the international agreement "About Comprehensive Nuclear Test Ban" which was accepted by the 50th session of the United Nations General Assembly in 1996. However, for more than 50th summer history of carrying out testing of nuclear weapon more than 2000 explosions were performed. These tests caused an irreparable loss to ecology of those places where they were made. First of all the main volume of radiation pollution of lands falls on the territories of test nuclear test sites. The list and the main characteristics of the largest nuclear test sites is provided in article. Most of them are preserved and weren't used for a long time. Such parameter as the area and level of radiation pollution of land is an important factor for territory zoning and land surveying for determination of the subsequent directions and opportunities of economic use of lands. On the basis of the made analysis of spatial structures on the lands adjacent to nuclear test sites, traditional housekeeping by indigenous people, and also degree of a demand of the land parcels for industrial and agricultural industry, it's reasonable to use the new term - forced land use on lands of nuclear test sites. The main features of forced land use are given in article. As an example the scheme of distribution of radiation pollution in borders of Semipalatinsk Test Site is made. On the existing classification of zone division of lands by pollution level radionuclides have offered the correction coefficients lowering the cadastral value of land during the cadastral valuation. The conclusion is drawn on need of implementation of monitoring researches on control of the level of radiation pollution and also to control processes of migration of radionuclides.
