Radioactive Winds Across the Pacific Ocean

The real nightmare of course is for anyone from Northeastern Japan down to Tokyo as the radiation spreads upon the winds. Likely having a battery powered or AC powered tester for radiation might be a necessity for most Japanese people very soon if not now.

However, my daughter and I were thinking today about how fast radioactive particles would be traveling on the wind towards the U.S. and North America. If I go back about 6 days it is about now when the really big 8.9 Earthquake occured. Then if I take an average (I took 20 miles per hour) of storms and winds which are the prevailing winds from Japan East across the Pacific(but it could be more or less than that). Then I took 20 mph times 24 hours a day times 6 days to get the average miles traveled(if 20 mph is an accurate assessment) and wound up with 2,880 miles in 6  24 hour days. Now also, that is just when the first really big earthquake occurred whereas now we are just beginning to see really serious radiation which is too much for men to work on Fukushima any longer if they want to remain alive more than one year or so.

Also, since I think it is around 5000 miles across the Pacific from Tokyo to San Francisco

Miles:	5133.13
Kilometers:	8260.74				So now if we take the amount of the average distance it might travel per day which would be 20 times 24 we get 480 miles per day (If you want kilometers I suggest figuring the full distance in miles before you convert to Kilometers so either use 480 for one day and convert or divide 5133.13 by 480 to get the possible average day it takes to get here. So it comes out to roughly 10.694+ days for it to get here. However, since the radiation didn't get that bad until Monday or Tuesday California time you should allow 9 or 10 days to get here from now. However, some of the radiation is now up in the jet stream because of the extreme heat and power of the hydrogen explosions. However, I'm not a mathemetician but here is possibly a way to calibrate this: November 18, 1952, when Pan Am flew from Tokyo to Honolulu at an altitude of 7,600 metres (24,900 ft). It cut the trip time by over one-third, from 18 to 11.5 hours.[2      So, if you can figure out what speed the Pan Am plane flew you can get an idea of the speed jet streams travel. I think jet streams are usually about 100 plus miles per hour most places and possibly as high as 200 miles per hour other places. The pan am quote is under the heading "jet streams" from wikipedia. So using the 20mph formula about 30 days more or less from now it will have radiated the whole northern hemisphere and be over Japan again. However, all the radiation eventually likely will be spread all over earth.
