We are just southeast of the plant on the gulf of Mexico and definitely in the first evac zone.
I do know you can build or make shelters - in a basement for example - that can protect you from most of the gamma radiation if you can stay in them a few days. Portable camp toilets, water, food, etc can all be stockpiled in there beforehand. Concrete block, heavy wood, then covered with heavy tarp/blankets and such will greatly reduce gamma ray damage.
