It’s less a matter of eliminating radiation than learning to live with radiation. People here could be scrubbing rooftops, discarding soil and unplugging tree roots for decades.

Yes, here in Japan, it's less a matter of eliminating radiation than learning to live with radiation. it's less a matter of eliminating stress than learning to live with stress. It's less a matter of making things more efficient than learning to live with inefficiencies. Gaman Gaman Gaman!

YOu dont live with radiation, you DIE with it. All these 'make you feel good, and like you are doing something' measures are in fact useless, just moving the contamination from rooftops, to gutters etc.

Evacuate and accept these places are uninhabitable.

I once thought that the Japanese were one of the lost tribes. I guess they really are now.

and even worse, 7.6 billion Bq of Neptunium

76 trillion Bq = 76 TBq (TeraBecquerels) actually. Personally I'd be more worried about the 140 TBq of Strontium-90. It seems that there is no testing going on for Sr-90 contamination anywhere in Japan, certainly I've seen no reports of testing for it or levels in food. And it's a killer, causing bone cancers and leukemia.

A bit of digging reveals that some testing for SR-90 has occurred, but it's not being publicised much here, probably because by now it's likely widespread in the milk supply. Perhaps it's time to switch to milk from Kyushu. But it's impossible to avoid milk products that are used in various processed foods, unfortunately.
