The relative intensity of cosmic ray sources in external galaxies of different types is estimated from the relative frequency of supernovae there. Also the cosmic ray energy in normal galaxies is estimated from radio astronomical data. It is found that the intensity and the lifetime of cosmic rays in spiral galaxies are nearly constant during their evolutional stage as spirals.
