In this paper, we investigate oscillatory Couette flow of an incompressible, conducting, viscous dusty fluid with non-conducting dust particles through a vertical channel filled with a saturated porous medium in presence of uniform magnetic field and radiative heat transfer. It is assumed that left wall of the channel is fixed while the right wall oscillates as it moves at time t > 0. The coupled partial differential equations governing the problem are solved via (approximate) perturbation techniques for temperature, velocity as well as skin friction for both dusty fluid and dust particles. The effects of radiation parameter N, volume fraction, porous parameter, on temperature, velocity, skin friction and wall heat transfer rate are displayed graphically and discussed qualitatively.
