It is actually estimated that if you get a glass of seawater (actually from any source, the following arguement would still "hold water" - pun) in any part of the world, spil it, drink it, do whatever you want...
After a few months (or is it years?), you do the same in ANY OTHER part of the world, you will catch a least one molecule of your original glass in it...
It is impossible for our layman minds to grasp how small a molecule really is and how fast it travels.
The whole volume of sea water on earth is estimated to be in the region of 315 Million cubic miles...that is an insane amount, right?
Cubic miles of seawater on Earth 315,000,000
cubic meters / cubic mile 4,165,509,529
m3 of seawater on Earth 1,312,135,501,635,000,000
Lt of seawater on Earth 1,312,135,501,635,000,000,000
lt in a glass (8oz/220ml) 0.22
Glasses of seawater on Earth 5,964,252,280,159,090,000,000.00 or
Our oceans contain more than 6 x 10^21 glasses of seawater
But...how many molecules does a glass of water contain? Thats a big number for sure...long story short, a 8oz glass of water contains ~7.5x10^24 molecules of water.
To put this in perspective, each glass of water contains more molecules than the total number of water glasses that exist not just in the oceans, but on Earth.
Actually it contains roughly 1,440 times more molecules than the oceans contain glasses of water.
So, there is roughly 1/1440 chance that the above won't be true...i.e. that for example each glass of water you are drinking today, even bottled (within the last 2 years), hasn't been exposed in Fucushima.
At the same time, many other molecules within this glass, have been exposed to Chernobyl radiation, the hundreds of nuclear tests, the actual nuclear bombings etc. Chances are that many of them were exposed to ALL of those.
Truth is, I have no idea how that affects what builds up in our body...
Maybe the molecules are cleansed once in gas form and it doesn't count any more...
But w/e it is in our oceans and is in molecular or sub-molecular form (radiation) has the ability to travel fast and - chances are - to be everywhere.Edited by pcfoo - 11/5/13 at 4:12pm
