  Gravitational field of a nonstatic global string has been studied in the
context 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
spacetime may or may not have any singularity at a finite distance from the
string core but the singularity at a particular time always remains. It has
been shown that the spacetime exhibits both outgoing and incoming gravitational
radiation.
