The object of the paper is to study the radiation effects on an unsteady free convective flow through a porous medium bounded by an oscillating plate with a variable wall temperature. The momentum and energy boundary layer equations have been solved by taking series expansions of velocity and temperature function in powers of product of magnetic field and time. The analytical solution of resulting ordinary differential equations has been obtained in terms of repeated integrals of complementary error functions. Also, the velocity and temperature profiles, for different values of the parameters, have been drawn and discussed.
