You could live there, it just isn't a very good place to live anymore. You would need to fly in your own food and water, and you'll still be getting irradiated

You could live there, it just isn't a very good place to live anymore. You would need to fly in your own food and water, and you'll still be getting irradiated, but we're talking "probably get cancer one day" irradiated, not "die of radiation sickness" irradiated. Bikini Atoll was also worse than this hypothetical Arkansas scenario in two ways: 1) The soil there is potassium poor, causing local plants to more readily take in radioactive cesium. 2) It was also hit by 22 additional bombs.
