Radioactivity from Fukushima Dai-ichi in air over Europe; part 2: What can it tell us about the accident ?
It is shown which information can be extracted from radionuclides emitted from the Fukushima I nuclear power plant and transported to Europe. In this part the focus will be on concentration ratios. While 131I, 134Cs and 137Cs were reported by most stations, other detected radionuclides, reported by some, are 136Cs, 132Te, 132I, and 129mTe, 140La and 95Nb. From their activity ratios burnup and temperature of the fuel from which they originated are estimated. Based on these data, inventories of radionuclides present at the time of the accident are calculated. In addition, these atmospheric radioactivity analyses allow inference on the status of the destroyed reactors at the time of the earthquake, and on release conditions.
