  We investigate the possibility of testing of the Einstein Equivalence
Principle (EEP) using measurements of anomalous magnetic moments of elementary
particles. We compute the one loop correction for the $g-2$ anomaly within the
class of non metric theories of gravity described by the \tmu formalism. We
find several novel mechanisms for breaking the EEP whose origin is due purely
to radiative corrections. We discuss the possibilities of setting new empirical
constraints on these effects.
