Abstract
Gravitational field of a nonstatic global string has been studied in the co ntext of Brans-Dicke theory of gravity. Both the metric components and the BD scalar field are assumed to be nonseparable functions of time and space. The space-time may or may not have any singularity at a finite distance fr om the string core but the singularity at a particular time always remains. It has been shown that the space-time exhibits both outgoing and incoming gravitational radiation.
