The decay asymmetries of the weak radiative Hyperon decays Xi0 \to Lambda gamma and Xi0 \to Sigma0 gamma have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 Xi0 \to Lambda gamma and 15000 Xi0 \to Sigma0 gamma decays, we obtain for the decay asymmetries alpha(Xi0 \to Lambda gamma) = -0.704 +/- 0.019(stat) +/- 0.064(syst) and alpha(Xi0 \to Sigma0 gamma) = -0.729 +/- 0.030(stat) +/- 0.076(syst), respectively. These results are in good agreement with previous experiments, but more precise.
