• In solving the continuity equation which describes the intensity of cosmic-ray electrons and positrons in interstellar space, one makes the a priori assumption that steady-state condition exists. In this paper we have investigated the condition under which this assumption is justified. We further show that if the cosmic rays are assumed to be confined uniformly throughout the galactic disc and the halo, then the age of the halo should be gsim 10^8 years to account for the agreement between the calculated and observed flux of positrons in the primary component of cosmic rays.
