The decay and radiation of an atom in a photonic crystal with an incomplete gap was investigated. If the transition frequency is close to a band edge, the Weisskopf-Wigner approximation is not applicable and the decay is nonexponential. The decay could be greatly enhanced or decreased by the self-emitted field.
