Total Radiation Inventory at Fukushima

 At the bottom of this post is a discussion of radiation releases from various sources over the course of the “nuclear age”, from ENENEWS.

A while back I spent about half a day to gather information and do some calculations.    Surprisingly, the NRC provided the data I needed directly to me.    That was sure useful of them.   

Here are the net results.      Truly an astounding amount of radiations at Fukushima.   Well, was at Fukushima, they “gifted” much of it to the world.

Arizonan, you may wish to look at the following and check out the radioactive waste discharged into the ocean:
http://en.wikipedia.org/wiki/ocean
The following comes from the above wikipedia link:
The countries involved — listed in order of total contributions measured in TBq (TBq=1012 Becquerel) — were the USSR, the UK, Switzerland, the US, Belgium, France, the Netherlands, Japan, Sweden, Russia, New Zealand, Germany, Italy and South Korea. Together, they dumped a total of 85,100 TBq (85.1x1015Bq) of radioactive waste at over 100 ocean sites, as measured in initial radioactivity at the time of dump.
For comparison:
magnitude of radiation
Global fallout of nuclear weapon tests — 2,566,087x1015Bq.[4]
1986 Chernobyl disaster total release — 12,060x1015Bq.[5]
2011 Fukushima Daiichi nuclear disaster, estimated total aerial release — 11,346x1015Bq.[6]
Fukishima Daiichi nuclear plant cooling water dumped (leaked) to the sea — TEPCO estimate 4.7x1015Bq, Japanese Nuclear Safety Commission estimate 15x1015Bq,[7] French Nuclear Safety Committee estimate 27x1015Bq.[8]
Naturally occurring Potassium 40 in all oceans — 14,000,000x1015Bq.[9]
One container (net 400kg) of vitrified high-level radioactive waste has an average radioactivity of 4x1015Bq (Max 45x1015Bq).
However, I do wonder where the US was storing their waste; I would have thought they would have had a similar amount to Britain and possibly the Soviet Union.
