  The amplitudes of $K \rightarrow \pi \gamma^* \rightarrow \pi e^+e^-$ and $K
\rightarrow \pi \pi \gamma$ decays have been calculated within chiral
Lagrangian approach including higher-order derivative terms and meson loops.
The selfconsistency of the simultaneous description of the experimental data on
the nonleptonic and radiative kaon decays have been demonstrated. We estimate
the effects of ``indirect'' and ``direct'' $CP$-violation in $K^0_L \rightarrow
\pi^0 e^+e^-$ decays and discuss $CP$-violating charge asymmetries in $K^{\pm}
\rightarrow \pi^{\pm} \pi^0 \gamma$ decays.
