I'm not an expert in radiation and I'm sure I've got a lot of mistakes in here, but there's so much misinformation out there that I figured a broad comparison of different types of dosages might be good anyway. I don't include too much about the Fukushima reactor because the situation seems to be changing by the hour, but I hope the chart provides some helpful context.
