The decay eta -> pi(+)pi(-)gamma has been measured with the WASA facility at COSY. The largest data set taken so far in an exclusive measurement was acquired, with 13740 +/- 140 events after background subtraction. Efficiency corrected Dalitz plot distributions have been extracted, which show the importance of final state interactions for the understanding of the decay.
