The attenuation of cosmic radio waves expected in the F region is calculated. It is shown that by using an F-region model obtained from electron backscatter measurements the attenuation obtained agrees well with observation. The amount of attenuation is generally less than 02 dB, providing the wave frequency is greater than twice f OF2 for wave frequencies less than 10 Mc/s.
