To what extent can the 'multi-generational' cleanup efforts be considered successful, and what scientific criteria are being used to determine when irradiated land is officially safe for permanent human habitation?
Beyond density and distance, what measures should be taken to ensure air filtration and ventilation remain safe to prevent inhaling radioactive particulates inside a shelter?
What are the specific contamination risks associated with using water from a tap versus bottled water during and immediately after a radiological release?
How does the duration of exposure to radioactive fallout dictate the specific choice of shelter, and is there a point where 'sheltering in place' becomes less safe than evacuation?
