They're all quite useful, demonstrating the enormous range of measurable radiation levels from that to which we're exposed in daily life up to the lethal doses. However, I think Alexandra's infographic is most useful as it also visualizes dose rate. This additional dimension does make Alexandra's chart a little more difficult to comprehend but it's worth the effort.
What do you think?
If you know of any other radiation dose charts then please let me know.
