I have done this also and it works for Fe 55. In general isotopes with
low energy xrays or auger electrons can be effectively analyzed by LSC.
This includes I 125, which can be useful in a university environment.
Depending on the type of smear paper, you may wish to allow the smear to
set in the cocktail to ensure optimal contact.

Do you mean in (not on) a LSC?
I have done this many years ago (no paper written). You need to be able
measure the K and L X-rays of Mn-55. The energies are K-sub alpha (5.90
100%; 5.89, 51%); K-sub beta (6.45keV, 16%). The percenatages are
to the K-sub alpha at 5.10 kev.
These photons do not excape the LS but produce electrons that are
in energy to those from tritium and if you can measure tritium you
able to measure Fe-55.
