We have measured the half-life of the {beta}{sup -} decay of {sup 198}Au to be 2.6948(9) d, with the nuclide sited in an insulating environment. Comparing this result with the half-life we measured previously with a metallic environment, we find the half-lives in both environments to be the same within 0.04%, thus contradicting a prediction that screening from a ''plasma'' of quasifree electrons in a metal increases the half-life by as much as 7%.
