We have measured the total collisional loss rate for ultracold sodium atoms held in a magneto-optical trap operating on the D1 line. The collisional rate is extracted from the decay of the fluorescence from trapped atoms. We observe an intensity dependence corresponding to radiative escape and hyperfine changing collisions in the trap. The results obtained are compared with previous measurements for traps operating on the D2 line.
