In a typical example one has

========= Table of registered couples ==============================

Index : 0     used in the geometry : Yes     recalculation needed : No
 Material : G4_AIR
 Range cuts        :  gamma 3 mum    e- 3 mum    e+ 3 mum
 Energy thresholds :  gamma 990 eV     e- 990 eV     e+ 990 eV
 Region(s) which use this couple :
    DefaultRegionForTheWorld

Index : 1     used in the geometry : Yes     recalculation needed : No
 Material : G4_PbWO4
 Range cuts        :  gamma 3 mum    e- 3 mum    e+ 3 mum
 Energy thresholds :  gamma 1.836 keV    e- 12.57 keV    e+ 12.42 keV
 Region(s) which use this couple :
    DefaultRegionForTheWorld

Index : 2     used in the geometry : Yes     recalculation needed : No
 Material : G4_Al
 Range cuts        :  gamma 3 mum    e- 3 mum    e+ 3 mum
 Energy thresholds :  gamma 990 eV     e- 4.11 keV    e+ 4.06 keV
 Region(s) which use this couple :
    DefaultRegionForTheWorld

....

of course, default cut is 1 mm , so production thresholds are about 1 MeV.
