Abstract
Radioactively contaminated territories after the Chernobyl accident
are characterized by non-stationary trends and soft (uncertain) information
about the average concentration of radionuclide in soil. Large-scale
decision-oriented mapping in this situation involves using the Neural
Network method to determine the general non-linear trends of the
data, and the BME method to analyze the hard and soft residual information
generated after the mean trend is removed from the data. In this
work we explore different approaches to map the residual soft data,
which include a Bayesian and a non-Bayesian framework. These approaches
are illustrated by means of the Cs137 mapping case study in Briansk,
Russia
