here's the google translation from the german for the original source:

The estimated source terms for iodine-131 are very constant, namely 1.3 10 17 Bq / day for the first two days (U.S. measurements) and 1.2 10 17 Bq / day for the third day (Japan). For cesium-137 measurements can the U.S. a source term of 5 10 15 Bq close, while Japan was much more air in the cesium in. On this day would Bq the source term with about 4 10 16 can be estimated.

In the nuclear catastrophe at Chernobyl was the entire source term of iodine-131 1.76 10 18 Bq of cesium-137 8.5 10 16 Bq. The estimated for Fukuschima source terms are thus at 20% of Chernobyl-term for iodine, and 20-60% of the Chernobyl-term for cesium.

After cesium-137 and make iodine-131 only a fraction of the total dose rate in the vicinity of the reactor, does not mean that local radiation exposure in Fukushima as high as in Chernobyl. The source terms to explain but the burden of food and water. The dose rates of cesium and iodine, resulting from our source hypothesis are much lower than those observed in total in Japan.


1) This report is based on two (day's?) reading in the US & one in Japan.
2) Based on those readings, the authors make further *estimations* about how much iodine & cesium is being emitted at the source on those days.
3) They estimate the "source terms" would be about 20% of chernobyl (for iodine) & 20-60% (for cesium.
