The average double decker bus weighs: 7tons/7950kgsConsuming radioactive material of ANY sort increases chances of cancer exponentially on an immediate timescale.And by ANY carbon allotrope I'm certain you mean Diamonds and Carbon-Nanotubes.

Exactly. A mutant that can live on with permanent cancer, has carbon nanotube muscle (maybe nerves too, as graphene is highly conductive. Though i may be wrong, so feel free to correct me) and a diamond exoskeleton. Morever, he can produce glassy carbon, which is highly acid resistant, allowing him to eat nearly anything he finds, combining this ability with the production of highly potent acid.
