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?
