I'm currently resident in Hong Kong a country which appars to import heavily from Japan.
Last saturday 7th May I went to a restaurant: http://www.openrice.com/english/restaurant/sr2.htm?shopid=39760
which I later discovered is themed after a popular Japanese coffee brand. I had one of those Fried Pork Chops in breadcrumbs which was served on a bed of white "pearl" rice with Japanese (style?) curry sauce
It occured to me that the rice may have been imported from Japan. I was interested in trying to identify the lifetime cancer risk from such a potential exposure. I have read that ingested isotopes are worse than external contaminations which can be washed away.
I'm aware that imports have been screened by the local goverment but from what I saw on the television it looked like they were just using dosimeters on the outside of cargo containers rather than in depth sampling.
I'm also wonder what types of isotopes would have been released in the fallout from Fukushima and in what ratios. I'm aware of Iodine 131, Caesium 134 and 147 and Strontium 90 but I've not seen any data on the ratios of what was released.
I've read that there are many Rice farms around Fukushima in Northern Japan and these provide approvimately 25% of the nations annual production.
