In recent articles [1-4], Jenkins et al. claim to have evidence that radioactive half-lives vary as a function of the earth-to-sun distance. They base their claims on data obtained by others over the space of several years -- the decay of ^32Si as measured at Brookhaven National Laboratory [5] from 1982-85 and that of ^226Ra as measured at the Physikalisch Technische Bundesanstalt in Germany [6] from 1984-88 -- in which the decay rates show a small but statistically significant oscillation with a period of one year and approximately correlated with the earth-sun distance (and with the seasons). Here we report a series of seven measurements of the ^198Au half-life (see [7] for a description of two of these) made by us at various intervals over a period of one aphelion-aphelion cycle. Each measured half-life has a precision of about 0.02%. There is no evidence of any deviation from a constant half-life. [1] J. H. Jenkins et al., Astropart. Phys. 31 407 (2009) [2] J. H.
