There is a Q-factor when dealing with radiation poisoning. Different radiation types have differing quality of damage. For example, gamma rays have very low quality. Human bodies aren't that dense and most gamma rays can pass right through you without even touching your atoms. It take more grays of gamma rays to cause harm than grays of beta particles. Alpha particles can effectively be stopped by your skin; if you get an alpha emitter on your skin, you can just wash it off and be fine. But if the alpha emitter gets inside your body, that same dose starts liquefying your organs.
In the case of radioactive potassium and carbon inside your body, it's much worse than what damage you'd get if that same material was outside your body. Add to that, while the low temperature of a body won't slow its radioactive decay, it will increase the absorption cross-section of your DNA.
