The effects of classical gravitational radiation in models with large extra
dimensions are investigated for ultra high energy cosmic rays (CRs). The cross
sections are implemented into a simulation package (SENECA) for high energy
hadron induced CR air showers. We predict that gravitational radiation from
quasi-elastic scattering could be observed at incident CR energies above 109
GeV for a setting with more than two extra dimensions. It is further shown that
this gravitational energy loss can alter the energy reconstruction for CR
energies ECR≥5⋅109 GeV
