A critical analysis of existing mathematical models of liquid spread on the earth's surface was carried out, which allowed us to identify their shortcomings and show low adequacy in modeling environmental pollution as a result of an accident/incident with the spill of radioactive liquids. It is determined that the main factors influencing the distribution of radioactive liquids in the environment as a result of spillage on the earth's surface are: duration and power of liquid spillage; soil and vegetation parameters; relief slope; characteristics of radioactive liquids; meteorological characteristics; time elapsed since the start of the accident/incident. A mathematical formulation of the problem of determining the distribution of radioactive liquid on the earth's surface as a result of an emergency spill, which, in contrast to existing ones, takes into account all major factors into the ground.
