Zoning of the territories of radioactive trace
The method is intended for performance of zoning of a radioactive trace of emergency emission basing on the value of the level of an effective dose rate above a ground surface in this or that moment after emission. The actual composition of radionuclides, which deposited on the ground surface, is taken into consideration. The method allows to determine actual location of the borders of the zones of radiation control, limited residing, eviction and alienation according to the level of the effective dose above the ground surface in this or that moment after the emission. It enables to carry out the zoning of radioactive traces beginning with the moment of the radionuclides composition of fallout on a ground surface determination, without waiting of the accumulation of set full annual doses. As a result it is possible to start carrying out of countermeasures on the territory of a radioactive trace correspondingly to the levels of expected doses in a due time, i.e. before people will receive the doses.
