Scientific paper

A list of giant H II regions in the Galaxy is compiled, and the number of Lyman continuum photons required to maintain the ionization of radio H II regions is counted. The dependence of photon flux on position in the Galaxy is derived, an initial mass function is considered, and the lifetime of a radio H II region is estimated. Star-formation rates are obtained from the photon counts, and data on the distribution of gas and total mass in the Galaxy are reviewed. Star formation is computed as a function of time. Predicted and observed star-formation rates are compared, and the best choice of a model is discussed.
