  Strong interactions between pairs of the K+ K- and K0 K0bar mesons can be
studied in radiative decays of phi(1020) mesons. We present a theoretical model
of the reactions e+ e- --> phi --> K+ K- gamma and e+ e- --> phi --> K0 K0bar
gamma. The K+ K- and K0 K0bar effective mass dependence of the differential
cross sections is derived. The total cross sections and the branching fractions
for the two radiative phi decays are calculated.
