I keep reading about Japan's radiation
 

I was planning on getting a job in teaching English like JET program, but I keep hearing about radiation fright and about earthquakes.

So I don't know what to do.

I guess you haven't read the thread(s) here regarding this.... I suggest you do, because there is good information there....

I would pay particular attention to posts from Nyororin....
