“ For the half-life of radioactive material often far exceeds the parameters of historical time, even as if infers, by its lethal effects, the principle of mortality. Further, since the half-life of a radioactive body may far exceed the duration of what we call “life” - like a god, it cannot be killed or eliminated - the radiant body functions at once as an emblem of immortality and, through the destructive effects on living flesh precipitated by its own decay, of ephemerality. ”
