Analysis of radiation monitoring near the npp "fukusima - 1"
The model of reconstruction of fields of losses of a polydisperse impurity from an instant source on a trace axis is offered. For the description of process of carrying over of aerosols in atmosphere the semiempirical equation of turbulent diffusion is used. The fractional structure of an impurity in a source on speeds of subsidence is set by means of double gamma distribution. Approbation of the model of reconstruction on the data of monitoring of emergency pollution of vicinities of radiochemical factory the atomic power station «Fukushima-1» is spent.
