Who owns the radioactive fallout from Japan?

Here's a good one-- the owners of the Fukushima No. 1 nuclear plant, which spewed radioactive materials over much of Japan, say they don't "own" the material, and that it now belongs to the people on whose property it fell!

A local golf course which is contaminated by radioactivity is concerned about its employees and its customers, and wants the Tokyo Electric Power Co. to clean up its property.  But Tokyo Electric Power Co. says the golf course will have to clean it up, because the golf course owns it!  See story at Asahi Shimbun. 

I wonder if Palmer Renewable Energy will say that the air pollution that would come from their proposed plant 'belongs" to the breather?
