Sorry this is so late. I just came back from holiday to an inbox full of requests to render up a Radiation Dosage chart.
Personally, I think XKCD has done a great job already. But I am here to serve.
Hopefully our chart will also help counter some of the confusion circulating about radiation and peril. Here also is a great piece by Anil Dash on understanding radiation exposure.
The data is here: http://bit.ly/RadiationChart
