  Starting from a Lagrangian, the electromagnetic field is quantized in the
presence of a body rotating along its axis of symmetry. Response functions and
fluctuation-dissipation relations are obtained. A general formula for
rotational friction and power radiated by a rotating dielectric body is
obtained in terms of the dyadic Green's tensor. Hamiltonian is determined and
possible generalizations are discussed. As an example, the rotational friction
and power radiated by a spherical dielectric in the vicinity of a semi-infinite
dielectric plane is obtained and discussed in some limiting cases.
