                     =============================

  Name           Description     
  ====           ===========

N < 100 keV   Low energy neutrons with E < 100 keV

N > 100 keV   High energy neutrons with E > 100 keV

Hadrons       Charged and neutral hadrons (mostly neutrons) with E > 20 MeV

MDT rate      MDT countingrate = 
              0.0005*neutrons + 0.0117*photons + (muons + protons + pions + 0.25*electrons) / 2

RPC rate      RPC countingrate =
              0.0001*neutrons + 0.0053*photons + (muons + protons + pions + 0.25*electrons) / 2

Penetrating   Penetrating particle rate =
              0.1*0.0117*photons + (muons + protons + pions + 0.25*electrons) / 2
