One of his other videos describes the people who are most exposed to radiation. The answer shocked me: https://youtu.be/TRL7o2kPqw0?t=9m

>The answer shocked me

You could make a good living as a journalist these days!

You won't believe how much these people have been exposed to radiation!

This man walks barefoot in Chernobyl. What he discovers next is unbelievable!

Government FURIOUS at this one weird trick used by a steam explosion to shed 2000 tons of concrete and steel plating.

That's a horribly misleading little segment there... the time scales were completely incompatible. A CT scan is an instantaneous event, a stay on the ISS lasts 6 months, and the smoker's lungs statistic is over an entire lifetime.

I guess as an ex-smoker, that piece of the video shocked me.

Apologies to all for the way I linked to the video. I've just learn what buzzfeed is, thanks to gjm11!

OK, I listened to this so that others don't have to (junto, good Buzzfeed impression, but please don't do it again). Allegedly (note: I haven't checked any of these figures, but I have tried to be a bit clearer about units):

Typical natural background radiation: 2mSv/year.

CT scan (one-off): 7mSv.

Total extra radiation (over a lifetime) for people around Fukushima: 10mSv.

US radiation workers' limit: 50mSv/year.

Astronauts on ISS: 160mSv/year.

Average smoker: 160mSv/year.

Obligatory: https://xkcd.com/radiation/
