Radiation Update - Japan 4/1

I have decided to keep a track on the levels of radiation, taking the figures from the Japan times which takes readings at about 5pm every day. I do not profess to understand how everything works, but I felt it a good idea to put this up. Japan is still open! And this is the second day of such a graph.

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!

No Miyagi?

Ask, and ye shall receive! I have added Miyagi in as of 4/2. Currently at 0.098, so not really a scary number at the moment...

I appreciate that.

On the 4/2 update I see Miyagi listed, but no data. (There are 7 prefectures and 6 lines.) Am I reading it wrong? Could you post a png instead of a bmp? It might be clearer.

Its on there, I am doing these quickly. As I get more time, I will re-edit older pics and get the line in. Miyagi is there! Pretty much smack in the middle of the pile!
