This was a good read, but they didn't mention how much radiation is dangerous. The power output of the decay is not relevant to people who are worried about radiation. This XKCD chart is a much better representation:

If someone is worried about banana's just tell them that eating a banana a day is as risky as sleeping next to another human.

(Probably less appealing is the statistic that eating a banana smoothie each day for 7 months is the same as getting one chest X-Ray every 7 months.)
