Characteristics of spectral line formation for monochromatic radio waves propagating in the turbulent plasma around the sun are analyzed for the case of a power-law turbulence spatial spectrum with finite values of the intrinsic and extrinsic turbulence scales. It is shown that normalization of the spectral line shape observed during radio occultation near the sun can be explained by the influence of the intrinsic turbulence scale. The values of the intrinsic turbulence scale are determined by using radio occultation data received from the Venera-10 spacecraft. With increasing distance from the sun, this intrinsic turbulence scale increases from the order of 2 km at distances of 6 solar radii to 20 km at distances of 20 solar radii.
