  Two kinds of the quantum electrodynamic radiative corrections to
electromagnetic interaction and their influence on properties of highly dense
quantum plasmas are considered. Linear radiative correction to the Coulomb
interaction are considered. Its contribution in the spectrum of the Langmuir
waves is presented. The second kind of the radiative corrections is related to
nonlinearity of the Maxwell equations for strong electromagnetic field. Its
contribution in spectrum of transverse waves of magnetized plasmas is briefly
discussed. At consideration of the Langmuir wave spectrum we included effect of
different distribution of the spin-up and spin-down electrons revealing in a
shift of the Fermi pressure.
