Re[2]: SI-units for radiation and activity
Just a word of thanks to Andy Hancock for his rational response to what was
turning out to be a rather ugly, jingoistic, thread here on RADSAFE. We all do
manage to get by. I buy my Coke in liters, and my gasoline in gallons. I work
in Curies and REM (hopefully not too many), and I read technical literature in
SI units, and I manage without much complaining.

Hi all
In the UK we use both, although I think there's a law that says we must
use SI units.
At our hospital all unsealed radiotherapy and brachytherapy doses are
prescribed by the medics in mCi quantities. Also our Chief Tech uses mCi
and I use MBq - we get by. When I tried to get her to change she said.
Look Amersham deal in mCi - therefore I order from them in mCi - nuff
said I suppose. You get a feel for both.
Also I was brought up on mR but my colleagues use mGy - again we get by.
In general the British are used to handling multiple units for similar
things. I buy my pre-packed food by the gram, but my fresh food by the
pound. I buy my petrol in litres yet my beer in pints. (incidentally the
units that maggots - for fishing, and prawns - for eating are dispensed
in is also pints!)
