If you are still suffering from exposure to toxins, here are some things to try. Pardon me if you've already tried them.

For most toxins, including radiation, try taking kelp. I use it in granulated form and stuff it in veggie capsules to try to avoid the sea taste. Take plenty, like five tsp. a day if it doesn't bother you. Buy it in bulk -- it's cheap.

Keep the liquids flowing and take a steady supply of Vit. C. around the clock. You could do this by nibbling on citrus (grapefruit ) or chard all day, or you can take small amounts of powdered Vit. C in water. You can usually take a couple of grams a day without getting the runs.

There are a ton of natural antioxidants found in fruits and veg. If they are not doing enough though, you might want to take a commerical "antioxidant" vitamin from a healthy food store. Also if you have symptoms of liver damage, consider taking Milk Thistle Seed.

Your best bet is a vegetarian diet with plenty of fresh foods and protein but not too high in fat. Toxins get stored in fat and you don't want that. Maintain your weight and don't overeat.
