Analyses of several radionuclide experiments give strong evidence that decay rates are NOT constant (as we have all been led to believe). To date, there is evidence for three periodicities: one with an annual period; a second with a period of order one month; and one that is approximately semi-annual. The first may be attributed partly to the eccentricity of the Earth's orbit, and partly to a north-south asymmetry in whatever solar radiation is responsible for the variations. The second may be attributed to the influence of solar rotation; however, the synodic period is in the range 30 - 33 days, indicative of a slowly rotating region - presumably the core. The third may be interpreted as a Rieger oscillation, except that it occurs in an inner tachocline (separating the core from the radiative zone) rather than in the outer tachocline, that separates the radiative zone from the convection zone. The mechanism by which the Sun influences nuclear decay rates is presently unknown. There are reasons to suspect that neutrinos are involved, but this would require that neutrinos have previously unsuspected properties.
