文摘

Sequentially reconstruct multi-nuclide emission using gamma dose rate measurements. Incorporate a priori ratio of nuclides into the background error covariance matrix. Sequentially augment and update the estimation and the background error covariance. Suppress the generation of negative estimations for the sequential method. Evaluate the new method with twin experiments based on the JRODOS system.
