Abstract：Nuclear decay is investigated by the view of network science and the relationship of nuclear decay among different radionuclide can be mapped to a network topology directly. The network includes 1410 nodes and 1275 edges. The average degree of the network of nuclear decay is about 1.8, the cumulative degree distribution still meets the typical power-law distribution, and the corresponding exponent is about 4.1.Not considering their dynamic behavior, the fitting parameters of the nuclear decay network are obtained according to the LUHNM theory proposed by our group before. Their cumulated degree distributions of the nuclear decay network match well. The idea and method may provide a new way to study some other problems of nuclear physics.
