People here have moved on and even learned to joke about the incident with an untraditional sarcasm. At dinner this evening, my friend asked the waiter “How’s the eggplant?” to which the waiter replied with a dry smile, “Oh don’t worry, we source that from another location now…”
The really bizarre thing is that the radiation levels are still really high… yet everyone is staying put. Tepco, the group that operates the failed nuclear reactors nearby, has been publishing all sorts of propaganda saying that radiation levels are falling. Nobody believes it.
A group of politicians staged a recent media stunt, drinking water that was supposedly filled from a puddle outside Fukushima’s reactors, and dining on local produce. Nobody seems to care.
Secret Paper?
This indicates that emissions were not only coming from the damaged reactor cores, but also from the spent-fuel pool of unit 4 and confirms that the spraying was an effective countermeasure. We also explore the main dispersion and deposition patterns of the radioactive cloud, both regionally for Japan as well as for the entire Northern Hemisphere. While at first sight it seemed fortunate that westerly winds prevailed most of the time during the accident, a different picture emerges from our detailed analysis. Exactly during and following the period of the strongest 137Cs emissions on 14 and 15 March as well as after another period with strong emissions on 19 March, the radioactive plume was advected over Eastern Honshu Island, where precipitation deposited a large fraction of 137Cs on land surfaces. The plume was also dispersed quickly over the entire Northern Hemisphere, first reaching North America on 15 March and Europe on 22 March. In general, simulated and observed concentrations of 133Xe and 137Cs both at Japanese as well as at remote sites were in good quantitative agreement with each other. Altogether, we estimate that 6.4 TBq of 137Cs, or 19% of the total fallout until 20 April, were deposited over Japanese land areas, while most of the rest fell over the North Pacific Ocean. Only 0.7 TBq, or 2% of the total fallout were deposited on land areas other than Japan.
