  We study the radiative decay $\phi\to\pi^{0}\pi^{0}\gamma$ within the
framework of a phenomenological approach in which the contributions of
$\sigma$-meson, $\rho$-meson and $f_0$-meson are considered. We analyze the
interference effects between different contributions and utilizing the
experimental branching ratio for this decay we estimate the coupling constant
$g_{\phi\sigma\gamma}$.
