A study is made of the dynamics of secondary ionization of plasma in models with a background of relic gravitating particles. It is conjectured that the source of the ionization of hydrogen is high-energy photons which arise in the decay of unstable massive particles or primordial black holes. It is shown that distortions arise in recombination dynamics only in the case when the half-life of the particles exceeds 3 x 10 to the 13th sec. It is noted that the rate of change of the Thomson scattering optical thickness of the plasma depends on the power of the ionizer and its lifetime. It is concluded that the nonequilibrium ionization of hydrogen at redshifts less than 1000 is an effective mechanism for the suppression of small-scale anisotropy in the microwave background radiation.
