Abstract

The article considers an approach of finding a rapid estimate of soil contamination density of plutonium isotopes in a radiological survey of agricultural lands on the south-western trace of Chernobyl radioactive fallout outside the Chernobyl Exclusion Zone. An algorithm based on a linear correlation between values of 90Sr and 238,239,240Pu activity in soil samples was developed. The algorithm was tested during a radiological field survey of abandoned lands in Narodychi district. The results of the approbation showed a satisfactory convergence of obtained estimates of soil contamination with plutonium isotopes of Chernobyl origin with experimental results. The proposed algorithm may be a part of the decision-making system at reviewing the boundaries of radioactive contamination zones and returning in the use agricultural lands that were abandoned after the Chernobyl accident
