For another elucidating example (and another Hillary situation), look at the CIA vs State Department in Benghazi.
The best numbers I can find seem to point to something in the 0.015 μSv to 0.88 μSv range. At cruising altitude, you get 0.04 μSv per minute from cosmic radiation.
I don't think the radiation from these machines should be the biggest concern.
I've found the more rural gas stations stock 100% gasoline. I assume it's because the older engines in farm and sporting equipment don't take kindly to E85 (different valve timing needed, it's rough on old seals, etc).
The teacher has had students over before, and unlocks his/her home by grabbing the key out of the fake rock sitting on the doorstep. The student uses that key and wrote something obscene with the fridge magnets.
It's not quite breaking and entering, but it's more than trespassing.
As for other impurities... there are a lot of radioactive crap in coal that is aerosolized during the combustion process. The most notable of these is uranium, which is carried away with the rest of the fly ash. There's a "shadow" around coal smoke stacks where such fly ash ends up accumulating. If it makes it into the water table or onto arable land that is used to grow crops, BAM, you've irradiated a small chunk of your population.
Depending on the source of the coal, there are various other heavy metals that can end up in your fly ash.
I got on a Baxter kick after powering through his Long Earth books (ostensibly coauthored with Terry Pratchett, though Pratchett's fingerprints are rather non-existent after first book). As long as you're ok with Baxter's strong dislike of organized religion, he seems to be one of the better modern science fiction writers.

When the GLAST (now James Webb Telescope) data came in, it pointed to a small (~1%) anisotropy of UHE GRBs toward high metalicity galaxies. Our model was completely isotropic. Unfortunately, we didn't have time to rework the anisotropy into our model's assumptions before our funding fell through.
... and that is the story of my brief experience as a scientist.
In the same way one or two bad drivers can destroy a lane or two of functional traffic flow, a good driver can create a lane (or two) of harmony.

I don't understand why you invoked the name of a Canadian popstar. There is no chance of such a comment adding to the discussion.
EDIT: answered my own question
I imagine the vocabulary isn't as difficult for machines to process as grammar.
