It is worth noting that this does open a new can of radioactive worms. External radiation exposure is over when you move away from the source, including washing off any dust. Internal exposure by breathing or ingesting the material is more than commitment to the immediate radiation dose. The material which is now internal will continue to decay with whatever its halflife is, resulting in ongoing exposure. "Safe levels" must be interpretted against this ongoing exposure, not time limited exposure. The limits on food need to be a LOT tougher than limits on workers at the plant (assuming they are wearing respirators that prevent inhalation of dust)
