New guide on how long should people stay in a nuclear shelter
PARIS (AFP) - A scientist published a guide on Wednesday to help authorities limit deaths from fallout after a city is hit by a nuclear bomb.
Taking cover in existing buildings is widely accepted as a critical first action after a nuclear blast in a major city.
But how long people should stay there before moving to better shelter is a more complex question.
Buildings that are lightweight or lack a basement are more easily penetrated by radioactive dust.
