Radio recombination lines are known to be observable at positions along the galactic ridge which are free of discrete continuum sources. Based on the results of a recent survey of H272α lines it is shown that most of the observed galactic ridge recombination lines can be explained as emission from outer low-density envelopes of normal HII regions. The distribution of low-density ionized gas and discrete HII regions as a function of the distance from the galactic centre is also derived.
