Hello

In the output file:
 TANTALUM
      Rho = 16.6540 g/cm**3 Rlc= 0.409392 cm
      Ae = 0.512999 MeV Ue = 4304.53 MeV
      Ap = 1.000000E-04 MeV Up = 4304.02 MeV
      dE/dx fluctuations activated for this medium, level 1
      below the threshold for explicit secondary electron production
     (up to 2I discrete levels, up to 2 K-edges)

Where Ae is the production threshold for electrons (total energy)
      Ap the same for photons
The U quantities are upper values for tabulations.

Further down you have the transport thresholds for each region:

1 Correspondence of regions and EMF-FLUKA material numbers and names:
       Region EMF FLUKA

          1 Blk 0 VACUUM 1 BLCKHOLE
          2 VOD 0 VACUUM 2 VACUUM
          3 BEAM 0 VACUUM 2 VACUUM
          4 TAR 1 TANTALUM 18 TANTALUM
  Prompt:
     Ecut = 5.1300E-01 MeV, Pcut = 1.0000E-04 MeV
     BIAS = F, Ray. = F, S(q,Z) = T, Pz(q,Z) = F, Acolin.= F
  Delayed:
     Ecut = 5.1300E-01 MeV, Pcut = 1.0000E-04 MeV

Hope this helps
Paola
