Abstract
The emission and absorption of gravitational waves and massless particles of an infinitely long straight cosmic string with finite thickness are studied. It is shown in a general term that the back reaction of the emission and absorption always makes the symmetry axis of the string singular. The singularity is a scalar singularity and cannot be removed.
