Estimated Contamination Potential of Fukushima Daiichi Nuclear Plant

In order to better understand the threat posed by Fukushima Daiichi nuclear power plant group member Edano has created some very rough estimates. These numbers are based on the worst case scenario numbers as produced by the UK government in this recently declassified document.

These estimates for Fukushima are for the total potential fuel on site, not for what has actually been released. The estimates for Fukushima refer to a worst case scenario where all the fuel on site would burn out and be completely released to the surrounding environment via wind and water leaks. The current situation is still far from this estimated worst case scenario here presented.

The estimated total potential material at Fukushima only includes cesium 137 and iodine 131. It does not include important isotopes such as stronium, plutonium and a long list of others.

A.  Fukushima
3 reactors / coriums:
cesium 137: 1e18 Bq = 1,000,000 TBq = 1,000,000,000,000,000,000 Bq
iodine 131: 7.2e18 Bq = 7,200,000 TBq = 7,200,000,000,000,000,000 Bq
6 Spent Fuel Pools:
—-> cesium 137: 2.2e18 Bq = 2,200,000 TBq = 2,200,000,000,000,000,000 Bq

B.  Chernobyl (all isotopes)
4 – 6.4e18 Bq = 4,000,000 TBq – 6,400,000 TBq = 4,000,000,000,000,000,000 –
6,400,000,000,000,000,000 Bq

Chernobyl total: 6,400,000  TBq (all isotopes)
Fukishima estimated total of partial isotopes: 10,400,000 TBq (partial isotopes)
