Guide to Radiation Doses

Randall Munroe of XKCD put together this fascinating chart of the “ionizing radiation dose a person can absorb from various sources;” from using a cell phone to CT Scans to being at Chernobyl and Fukushima when disaster struck.

Munroe received help from Ellen, a Senior Reactor Operator at the Reed Research Reactor, and you can find a list of the sources used here.

As far as accuracy, Munroe also adds:

“It’s for education purposed only. If you’re basing radiation safety procedures on an internet PNG image and things go wrong, you have no one to blame but yourself.”
