The objective of the present paper is to investigate thermal radiation effects on unsteady flow past a parabolic accelerated isothermal vertical plate with uniform heat and mass diffusion under the influence of applied transverse magnetic field. The fluid considered here is a grey, absorbing-emitting radiation but a non-scattering medium. The governing equations involved in the present analysis are solved by Laplace transform technique. The velocity, temperature, concentration and skin friction are studied for different parameters like Schmidt number, thermal Grashof number, mass Grashof number, Prandtl number and magnetic field parameter. The velocity increases with increasing values of thermal Grashof number or mass Grashof number, Schmidt number and the magnetic field parameter, but the trend is reversed with respect to the thermal radiation parameter. The temperature of the plate increases with decreasing values of the thermal radiation parameter.
