Abstract:	We propose an exact formula for the energy radiated by an accelerating quark in N = 2 superconformal theories in four dimensions. This formula reproduces the known bremsstrahlung function for N = 4 theories and provides a prediction for all the perturbative and instanton corrections in N = 2 theories. We perform a perturbative check of our proposal up to three loops.
