We estimate the ''hardness factors'' and the equivalent 1 MeV neutron
fluences of the hadron radiation level at the proposed GaAs forward tr
acker wheels in the ATLAS inner detector. On this basis, a prediction
is given of the degradation of the GaAs particle detectors made on dif
ferent substrates as a function of years of LHC operation.
