1. People in the US, stop freaking out... and for heaven's sake, stop hoarding potassium iodide pills.
2. Let's pretend that all the reactors blew up and a radioactive cloud goes into the air...
- the cloud will follow the wind currents
- there will be settling of materials (things with mass will fall because of gravity) so this means a lot of it will be deposited in the ocean.
- Rain could make the radioactive particles deposit on the ground or sea
- by virtue of being airborne it will disperse and the concentration will decrease (kind of like LA's smog floating west and by the time it reaches Las Vegas, the smog concentration is low)
- It is good that they are on the coast and there is a lot of ocean
4. Don't believe most of what you hear in the media.
- I nearly died when the CNN weatherperson explained how a nuclear reactor worked.
- You are not a nuclear expert if you don't have a degree in nuclear engineering, health physics, or some sort of radiological science.
- Most media will try to make you fear and give misinformation or blatantly wrong info or interpret info in a horrible way.
- Here's some good websites: http://www.nrc.gov/reading-rm/basic-ref/students.html and http://nei.cachefly.net/newsandevents/information-on-the-japanese-earthquake-and-reactors-in-that-region/ and http://www.energy.gov/ and http://www.hps.org/
