Abstract

One of the main uses of radiation aerial monitoring is in the mapping of an area contaminated by radioactive isotopes. In this work, we will introduce two independent approaches, redundancy and complementary methods, to estimate the radiation activity level of a contaminated area, using air monitoring information. Due to mathematical limitations, aerial monitoring of a radioactive field can not provide a 3d distribution of the contamination within the radioactive cloud. However, a reasonably good estimation of the 2d contamination distribution on the ground can be obtained by measuring the radioactive field from a constant height of 100 to 500 meters. Two complementary independent approaches have to be used in order to solve this problem: the elementary matrix solution after a conditional simulation and the application based on Stein equation.
