Abstract	We investigate automatic γ-ray photon quenching in compact non-thermal sources. This is an auto-regulating network of processes that consists of photon-photon absorption and synchrotron emission of the produced e- e+ pairs and operates non linearly whenever the γ-ray luminosity exceeds a critical value. We present expressions for this quantity and discuss our results.
