  In the SND experiment at the VEPP-2M electron-positron collider the
PHI(1020)--->PI0+PI0+GAMMA decay was studied. The branching ratio
B(PHI--->PI0+PI0+GAMMA)=(1.14+-0.10+-0.12)x10^{-4} was measured. It was shown,
that the F0(980)GAMMA mechanism dominates in this decay and the 4-quark model
of F0(980) describes our data most consistently.
