Measuring radiation levels
I'm re-linking this article with a chart of comparable radiation doses in micro-Sieverts. Doses I've seen so far have been in this unit, but I've seen a couple of measurements in milli-Sieverts (1000 micro-Sieverts). Watch that carefully. I hope the journalists are.
Another article on dosages here.
1 rem is 10,000 micro-Sieverts, or 10 milli-Sieverts.
