Abstract :
Alpha particles are one of the main sources of soft errors at ground level due to radioactive impurities found in electronic materials. In this paper, based on the radioactive decay laws, we identify radioactive nuclides that may enhance the alpha disintegration rate when secular equilibrium is not reached.
