Radioactive Contamination Estimation Based on Airborne Detectors Measurements

In case of a nuclear accident, it is important to estimate the nuclear fallout, i.e., the contamination left on the ground surface after the polluted plume has passed. A common radiation measurement of the contaminated area utilizes airborne radiation monitoring systems. An innovative method for estimation of nuclear fallout activity is suggested, using the airborne detectors' radiation measurements. Several estimation algorithms were investigated, however they proved to be bound to limitations such as non convergence of the results, poor resolution, high noise sensitivity and more. The superior performance, robustness to diverse noisy conditions and high resolution capabilities made the suggested method ideal for contamination estimation
