My understanding is that this is from the radioactive carbon-14 isotope which is in the CO2 emitted, at something like one part per trillion. So it should apply to any non-CCS powerplant. But it's still misleading, since essentially all of that CO2 will remain in the atmosphere, while radioactivity in the form of uranium, plutonium etc. will all rain down to the ground quickly (i.e. "fallout"). Edit: I remembered wrong, carbon-14 isn't the problem. It's uranium etc. in the ash from coal powerplants. Disregard this post.
