Space- and time-resolved measurements of the luminosity distribution of the MT-1 Tokamak plasma during density limit disruptions are presented. The energy ranges investigated are 30-80 eV, 80-300 eV and 400 eV-10 keV. Along with the 2/1 mode magnetic island in several cases a 1/1 mode was also detected prior to the occurrence of the instabilities. Energy outflow from the hot core to the 2/1 mode is seen in the 80-300 eV energy interval and a radiation increase, possibly caused by impurity influx, is seen in the 30-80 eV energy range during disruption.
