Re: Sm-153

[Richard Smart <R.Smart@unsw.edu.au>]

Further to my last message on this topic I have tracked down the
specifications for Quadramet.  There is a limit of 0.0093% of Eu-154 at
calibration time of the Sm-153.

We are supplied in single dose vials containing 6 GBq of Sm-153.  This
gives a maximum activity of Eu-154 of 0.56 MBq.  

Australian Radioiosotopes, the manufacturer of Quadramet in Australia, have
consistently measured activities of Eu-154 that are a factor of 10 less
than the specification, ie between 0.0005% and 0.0009%.
