We describe a relativistic approach to the calculation of nucleon-nucl
eon Bremsstrahlung, where all meson-baryon and meson-baryon-photon int
eractions can be calculated consistently and microscopically In this f
irst relativistic apl!roach to the problem, we present numerical resul
ts including both single-scatter and rescatter contributions with a re
lativistic current density, within a model where the explicit photon c
oupling to meson-exchange currents are small. The need for high precis
ion (p, p gamma) measurements is stressed.
