As part of the bulletin’s warning, individuals are told to get inside to the nearest building to avoid radiation and remove contaminated clothing that could have come in contact with debris when the fallout from the attack occurred.

“Go to the basement or middle of the building,” the government advises. “Stay away from the outer walls and roofs. Try to maintain a distance of at least six feet between yourself and people who are not part of your household. If possible, wear a mask if you’re sheltering with people who are not a part of your household.”

Pending further instruction, individuals are instructed to remain indoors for 24 hours and “continue to practice social distancing by wearing a mask and by keeping a distance of at least six feet between yourself and people who are not part of your household.”

The bulletin makes an exception to the rules for “children under two years old, people who have trouble breathing, and those who are unable to remove masks on their own.”
