  1. *1Activity levels were calculated assuming that the larvae ate all of the leaves required for their subsequent growth at once on the first day of ingestion of the contaminated leaves and that 137Cs and 134Cs were released at a 1:1 activity ratio on 15 March 2011 in a single burst from the Fukushima Dai-ichi NPP.
