Unless there is a strong, steady, horizontal wind from Japan to the East Coast, you won't need any pills, etc to "combat" the radiation. My inclination is to go into a thyroid rant here but I won't... buy my book "Fattitude: Lose your F in Attitude" instead; it's there.




However, here is what we do need to think about. 




1. BP leak. Still a mess, and we have conveniently forgotten about it even though most of the toxins are bio-accumulative, meaning, we are higher up on the food chain "yay" which means we will get hit worst "boo" with the toxins. So the flopping dead fish or the freakshow that may be hatching in the oceans from the leak, are just a snapshot of our future.  Just because we moved it around and made the mess less obvious doesn't mean it isn't as dangerous. 




2. The toxins now in the water from Japan, yea, we should worry. Same reasons as stated above. Some toxins are bio-accumulative.




3. Nuclear issues and water:  

  3a. Thermal = rush of warmer water = algae going ape crazy and decrease oxygen in the water, shorter life span for plants, less health of whatever lives in the water and you got it, more toxins;we may end up eating it. Or our children. It may find it's way into our cells. 




 3b. Migration. The stuff in the ocean already a mess from Japan ... the stuff that is alive. It won't be staying there long. It's infected (probably) and moving out. Maybe near us.




3c. Shock. Even the smallest temperature or water change can kill an organism or sea life. Ask the most careful adult or teen if they ever mistakenly killed a goldfish or beta fish; see what I mean? Now imagine a toxic dump in the ocean with water temp changes.  




 3d. Radioactive. "Slightly radioactive" is like "a little bit pregnant".  It isn't good and like pregnancy, there is a process and there is a result. However, there is radiation coming from earth naturally, there is cosmic radiation and this is not counting the medical radiation we've all encountered. That being said the amount that may release and distribute may be nothing. There is something like 80%+ percent of the radiation coming from Radon, and only 11% from medical... to give you an idea. Most of our issues from radiation are from below us already.




All of this means, again, we are fighting a toxic ecosystem and the more you focus on a healthy lifestyle the better. No need for emotional meltdowns nor being ignorantly bliss; just be smart, research the science behind what the media reports. Many people get mad at "the media" but there is no one stopping us from researching on our own. Make your own decisions upon what is right for you.
