Not everyone was so lucky. Three tiny islands some hundred miles to the east of Bikini were hit hard. On the island of Rongerik, twenty-six American sailors stationed to make weather observations knew enough to wash immediately, put on extra clothes, and stay inside their tents. But no one had bothered to tell the Marshall Islanders about their vulnerability to the most terrible of modern weapons. American medical teams were rushed to all three islands. Luckily on Rongerik, the worst radiation occurred in unpopulated areas.
