【 摘 要 】

The article considers the possibility of using the method of random addition to simulate radioactive contamination of the area under conditions of significant uncertainty of the wind in the surface layer during the spread of radioactive substances. The analogy between the existing methods of construction of relief surfaces and the construction of a model of radioactive contamination is considered. The algorithm allowing to build the specified surfaces on known values of density of radioactive pollution in a small number of set points is described. The values characterizing forecast errors are estimated in advance. The article concludes a possibility of application of random additions algorithm for simulation of radiation contamination in the accident at radiation-hazardous objects (RHO). The considered modification of the algorithm makes it possible to build a model of the density of radioactive contamination by known fixed points.
