Abstract
We study quantum radiation generated by the accelerated motion of a small b ody with a refractive index n which differs slightly from 1. To simplify ca lculations we consider a model with a scaler massless field. We use the per turbation expansion in a small parameter n - 1 to obtain a correction to th e vacuum Hadamard function for a uniformly accelerated motion of the body. We obtain the vacuum expectation for the energy density flux in the wave zo ne and discuss its properties.
