Gamma-Ray Bursts (GRBs) production is discussed in the framework of the Brans-Dicke (BD) theory of gravity. We derive the effective potential and the acceleration of a scalar particle propagating in a gravitational field described by BD theory. The rate of the energy radiated by charged particles is also calculated. Constraints on parameters entering the BD theory are fixed in order to reproduce the typical outputs energy of GRBs.
