  The idea of new diagnostics method for the small-scale irregular structures
of magnetically confined plasma is suggested in the present paper. The method
can be based on measurements of intensity attenuation of the normal sounding
waves. Anomalous attenuation arises due to multiple scattering effects
investigated earlier for ionospheric radio propagation. It has been shown that
multiple scattering regime can realize in a tokamak plasma. Calculations of
normal sounding wave anomalous attenuation in a tokamak plasma have been
carried out. This quantity is large enough to be registered experimentally.
