The creation of particles by a nonstationary gravitational field during the formation of a straight, static cosmic string has been investigated and the contribution to the number density of created particles from modes with the lowest angular quantum number assessed. It is found that for GUT scale strings the energy density of created particles is many orders of magnitude smaller than the corresponding energy density of radiation at GUT times.
