Here are some basic numbers to use as a guide (μSv means microSieverts):
10 μSv – The average radiation you received today
40 μSv – The radiation you receive by taking a flight from New York to L.A.
100 μSv – The radiation you receive during a dental x-ray
800 μSv – Total radiation dose at Three-Mile Island for the duration of the accident
3,000 μSv – Radiation dose from a mammogram
3,600 μSv – Average radiation a US citizen receives in a year from all sources
50,000 μSv – Maximum allowable yearly occupational dose (USA)
100,000 μSv – Lowest yearly dose likely linked to increased cancer risk
2,000,000 μSv – Severe radiation poisoning (sometimes fatal)
Tokyo usually has a background radiation level of .04 μSv/h. On April 5, [2011] the level was .12 μSv/h. That’s more than double, but is it dangerous? The short answer is no. If we multiply .12 by the number of hours in a year (about 8766) we see that a Tokyo resident would receive about 1,052 μSv of radiation a year at current levels. That is about 2% of the amount that the USA allows workers to receive on the job, or about a third of the amount the average American receives per year from all sources.

I've thought of taking some measurements at my local supermarket(in the United States) of some of the pacific sourced sea food.
Figured it would look a bit odd though. I would still need to be able to go there and get my groceries in the future.

Why not just buy the seafood and measure it back at home before you cook/eat it ? Unless you don't eat sea food in which case it's a bit of a waste (not sure why you'd be concerned about radiation in sea food if you don't eat it though)

So radiation is safe for consumption I see.
No more mayo or mustard for me.
Can I get extra radiation on my triple burger deluxe?

A lot of bananas have radioactivity in them. It is radioactive potassium. I tested some I had one day and there was an increase, but the next time I tested them there wasn't hardly a change at all. I put a piece of charcoal near the stream of running water at the sink, and the charcoal absorbed the radon and it jumped up quite a bit. The type of radon we have is probably harmless. Hmmm. I am sort of bald though, but nobody else is in the house so I guess that isn't relevant..
I have not tested seaweed at all, but I would think that since there were numerous tests done on Islands in the past, it all would be a little contaminated. I guess that is why the bananas have radiation in them....at least that is what I read anyway. Knowing how misinterpretations work, I doubt if nuclear explosions had much of an effect on the bananas. When I mixed the salt and sand together in a bucket in the shed, the detector picked up radioactive activity there near the bucket. None of this was as much radiation as the dials on the baby ben or big ben clocks I have. I grew up with a big ben clock right next to my head on the nightstand when I slept, I used these alarm clocks for the first thirty five years of my life. Maybe that is why I do not have hair, my dad and brother were bald and they both slept next to the clock. Yeah, I guess I have been watching too much Sci-fi. That third eye I have is completely normal.
