Do you mean in (not on) a LSC?

I have done this many years ago (no paper written). You need to be able to 
measure the K and L X-rays of Mn-55. The energies are K-sub alpha (5.90 keV, 
100%; 5.89, 51%); K-sub beta (6.45keV, 16%). The percenatages are relative 
to  the K-sub alpha at 5.10 kev.

These photons do not excape the LS but  produce electrons that are similar 
in energy to those from tritium and if you can measure tritium you should be 
able to measure Fe-55.
