We focus on special domains of sterile neutrino masses $m_{N}$ where it is close to its mass-shell. This leads to an enormous resonant enhancement of the decay rates of these processes. This allows us to derive stringent limits on the sterile neutrino mass $m_{N}$ and its mixing $U_{\\alpha N}$ with active flavors. We apply a joint analysis of the existing experimental bounds on the decay rates of the studied processes.
