We utilized the duality between massive vector and massive Kalb-Ramond fields to derive an effective action for Abelian-Higgs cosmic strings. This enabled us to determine the classically renormalized string tension and facilitate calculations for back-reaction effects. Additionally, we derived a comprehensive expression for the energy flux of radiation emitted by Abelian-Higgs cosmic strings. Applying this equation to a cuspless loop, we obtained that the loop lifetime is proportional to the square of the loop length, which is in agreement with field-theory simulations.
