Teachers have been getting a right kicking recently and it's not fair. So, let's hear it for the teachers who've inspired you, made you laugh, or helped you to make massive explosions in the chemistry lab. (Thanks to Godwin's Lawyer for the suggestion)

Although a kilogram? I'm not sure if it is even kept in those quantities. The risk, not to mention radiation would be too great, surely?

it was a few containers of the stuff, diligently pinched from several lab stores... I'm guessing kilogram was an exaggeration (certainly on my part if not his). I really hope it was the non-radioactive kind but I wouldn't be surprised if that oversight explains why he didn't do so well in that class! Have to admit I don't know a lot about it, I figured it's best not to question someone with a history of disruptive behaviour and a ready supply of volatile substances :)

The metal is not as useful as its rather less dangerous salts.
And as for radiation, the major isotope (133Cs) is not radioactive. The main radioactive isotope (137Cs) is only found in nuclear waste.

I never delved that far into it. So far as I think, if an element's name ends in "-um" then its radioactive, i.e. polonium, radium, uranium etc.
Well, apart from aluminium. I'm not that daft.
