Here is a good calculator for radiation exposure. Since you are only x raying your foot, there should be very little consequence. If I had one foot x-ray, I would receive 0.01mSv. (Wow. It's NOTHING. XD) The only concern would be when you are having a full body/abdominal/back x ray because your vital systems are being exposed.
I think the supplement you are talking about is astaxanthin. It's an extremely powerful antioxidant; it protects against DNA damage. It's also an EXCELLENT internal sunscreen. I like to tan in the nude a lot, and with astaxanthin my skin has become very resistant to redness/burning/peeling. There was a huge difference even on about 1.25mg/day. I don't take the isolated form but the isolated forms usually have much higher doses 4-8mg/pill. The krill oil I happen to take has a significant amount of it.
Screw iodide pills. This will probably do much more good for the people on the coast if radiation actually turns out to be bad.
Some good natural food sources: Salmon, shrimp, krill. (It is why they are orange. Farm raised salmon is pale because it doesn't receive much of this nutrient.)
I would think that vitamin E(tocopherol/tocotrienol) would also have a protective effect. It would be much less effective though.
