The solution of the radiative transfer equation taking account of the polarization state of the radiation
field is an important problem. The light emitted by any physical system is polarized only if there exists an intrinsic anisotropy in the medium, in which the radiation interacts with matter. The anisotropy in both microscopic as well as macroscopic scales produces a net polarization of the diffuse radiation field in the medium. The equation of radiative transfer establishes a natural link between the microphysical quantities like absorption and scattering coefficients, refractive indices etc.and thermodynamic quantities such as temperature and radiative flux gradients as well as the geometric structure of the medium. Hence a correct theoretical
interpretation of the observed polarization data using the theory of polarization radiative transfer offers a better chance to determine the physical state of the matter in the emitting regions and the spatial, temporal and geometrical parameters of these regions. These parameters are the basic data needed in further studies of any astrophysical problem. In this thesis we have made an attempt to develop general solutions of the problem of radiative transfer for polarized radintion field. We mainly use the Stokes
vector representation in the polarization transfer equations.
