Following the Fukushima nuclear power plant accident detections of ¹³³Xe have been made in various locations. Using results of these remote measurements the Fukushima ¹³³Xe source term has been reconstructed and compared with previously reconstructed ¹³⁷Cs and ¹³¹I source terms. The reconstruction is accomplished by applying atmospheric transport modeling and an adapted least square error method. The obtained results are in agreement with previous estimations of the Fukushima radionuclide source, and also serve as a proof of principle for source term reconstruction based on atmospheric transport modeling.
