The article says the banana equivalent dose concept was intended to ridicule people who were afraid of nuclear power plant accidents. Such accidents would expose people to radioactive iodine, which, in the article itself says: "The combination of bioaccumulation and the greater penetrating power of ionizing Gamma radiation makes radioactive Iodine significantly more hazardous to humans than equivalent amounts of Potassium-40". So no, being in the vicinity of a nuclear accident at dose X of Gamma + Beta radiation in the form of iodine that is going to be absorbed into the thyroid (leading to continued further exposure) cannot be meaningfully compared to the same dose of just Beta radiation from potassium that is passed through the body and excreted.
