The dust-jet radial brightness has been analysed along jet cores on images taken by the TV experiment aboard VEGA-2 spacecraft on 9 March 1986 during the close encounter with Comet Halley. Applying the RFIT code - used in reactor physics - to the data, it has been shown that there is a breakpoint in the radial brightness distribution which occurs at about 40 km above the surface. We interpret this result as being due to heat-shock included desintegration of dust particles as they are ejected into the near-nucleus environment.
