I'll be the first to admit it - I'd never even heard of microsieverts, and I grew up during the Cold War, until a couple of months ago when the Fukushima Daiichi nuclear plant blew its lid post March 11 earthquake and tsunami.
Given that I live in Tokyo, we're said to be far safer than residents in Fukushima itself, since we're 230km from the ongoing fiasco. Mostly I like to believe that, but it's tricky when you harbour some suspicions about TEPCO, the owners of the plant, and just how much information the Japanese government is giving out.
Things like bunnies born without ears, irradiated tea, and YouTube clips of Geiger counter readings in playgrounds in nearby Kashiwa, here in Tokyo, do cause you to fret just a wee bit. The only thing to do is to keep a baker's dozen of eyes on all sources of info - official and hysterical - and draw a line somewhere down the middle.
That and a lucky rabbit's foot will hopefully see things through. Right?
