Integral form of radiative transfer equation in inhomogeneous cylindrical medium with anisotropic scattering

The integral form of the radiative transfer equation in an inhomogeneous cylindrical medium with anisotropic scattering is derived. The medium is considered to have an internal space-dependent energy source and diffuse reflecting boundary illuminated by external incidence. The integral form contains the effects of the boundary condition and the internal source. The solution of the integral form does not need the particular solution due to the free term of the integrodifferential form. Also, the integral form reduces the three independent parameters of the radiative transfer equation to only one parameter which facilitates the solution of the equation.
