We consider the total energy loss and spectral density of uniformly movingelectrically charged particles in the spacetime of a wormhole with aninfinitely short throat. We show that the total energy loss $\mathcal{E} \sime^2v\gamma a^2/b^3$, where $\gamma$ is relativistic factor, $a$ is the radiusof the wormhole's throat and $b$ is the impact factor. The spectrum of theenergy for particles radially moving through the wormhole's throat $\mathcal{E}\sim e^2v\gamma/a$. The spectral density of the total energy has a maximum atfrequency $\omega_m \sim v\gamma/b$ and at $\omega_m \sim v\gamma /a$ forradial motion.
