After a couple of days away, now back in front of the computer, I can give you an updated chart with the last couple of days added. Radiation is slowly creeping down. Despite all the news about Fukushima having to ditch radioactive water, and cracks, and leaks, etc.
I have selected several prefectures, including my own, which are round Fukushima.
I have not included Ibaraki, as that just stretches the graph up a lot, and trying to add Fukushima will just be silly!
Just to put it into perspective.
All this radiation is measured in microsieverts per hour. Just to put it into perspective, a chest X-ray will see you get blasted by 50 microsieverts, a flight from tokyo to New York and back, will see you subjected to 190 microsieverts, and should you require a serious stomach X-ray, thats 600 microsieverts.
Also, the average person per year, through using the microwave and other objects will receive 2400 microsieverts. A CAT scan will see you walloped with 6900 microsieverts, and the maximum a nuclear power worker is allowed is 50,000 microsieverts.
Finally, at 100,000 microsieverts, your risk of cancer will increase! By a massive 0.5%!
So, I have my iodine tablets, but I am not unduly worried!
