Abstract: 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 H272 alpha 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 H II regions. The distribution of low-density ionized gas and discrete H II regions as a function of the distance from the Galactic center is also derived.
