Steady-state radiative transfer in filamentary prominence structures is analyzed in the case of a two-level atom. Both diffuse radiation and direct solar radiation are considered for a system of filaments, and the steady-state transfer equation is solved for two values of a parameter corresponding, respectively, to resonance (H-alpha) radiation and ionization equilibrium. It is concluded that: (1) the source function of H-alpha radiation tends to increase with optical depth in a filamentary prominence, but somewhat less pronouncedly than in a homogeneous prominence; (2) the source function decreases slowly with optical depth in the case corresponding to ionization equilibrium; (3) the source function in filamentary prominences tends to a constant value corresponding to its value at the surface; and (4) for a whole-prominence optical depth much greater than unity, the profiles of resonance lines from filamentary prominences experience a smaller self-reversal than the profiles of lines produced in homogeneous prominences of the same optical depth.
