The injection of sodium as a trace contaminant into a laminar boundary layer was considered. Three ionizing reactions were studied and it was found that the ionization by collision with atomic oxygen was the most significant. The peak electron concentration was determined as a function of the scaling parameter, PxU sub e. Comparisons were made with the predicted clean air variations with the same parameter. Stream tube predictions neglecting diffusion were also made and compared with the more exact results. The relative ionization of clean air and sodium was assessed as a function of altitude and amount of injection material. Bortners rates were used for the nonequilibrium sodium ionization.
