Several sources suggest that Kelp may be used to treat the affects of radiation on the body. Many “green foods” such as kelp, seaweed, wheat grass or any other source of chlorophyll will have similar properties. Kelp has a normalizing effect on the thyroid gland. you must also be sure to get enough vitamin A in your diet. without sufficient vitamin A, your thyroid gland cannot produce thyroxin, a hormone that helps the thyroid absorb iodine.
Rosemary
In fact, this headline states Rosemary Found to Offer Best Protection Against Radiation Poisoning. That speaks loudly enough, don’t you think? In addition to eating the herb fresh or dried (and cooked into dishes), you can also find rosemary extract or tincture in just about any natural health food store.
Spurilina
“In Chernobyl, for instance, spirulina was used to help save many children from radiation poisoning. By taking 5 grams of spirulina a day for 45 days, the Institute of Radiation Medicine in Minsk even proved that children on this protocol experienced enhanced immune systems, T-cell counts and reduced radioactivity. Israeli scientists have since treated Chernobyl children with doses of natural beta carotene from Dunaliella algae and proved that it helped normalize their blood chemistry. Chlorella algae, a known immune system builder and heavy metal detoxifier, has also shown radioprotective effects. Because they bind heavy metals, algae should therefore be consumed after exposure to any type of radioactive contamination.” Read more about spirulina
Miso Soup
Shinichiro Akizuki, M.D. helped the patients at St. Francis Hospital avoid radiation poisoning after the atomic bombing of Nagasaki in 1945 by feeding his patients and workers brown rice, miso soup, vegetables and seaweed every day. His hospital was only about a mile from the blast site. Further away, University Hospital's 3000 patients suffered greatly from leukemia and disfiguring radiation burns. This hospital served its patients sugar, white rice, and refined white flour products. A follow-up study was done on the health of the Japanese people. Over a 25-year period, the Japanese Cancer Institute tested and tracked 260,000 subjects, dividing them into three groups. Group one ate miso soup daily, group two consumed miso two or three times a week, while group three ate no miso at all. The results were stark: those who had not eaten any miso showed a 50% higher incidence of cancer than those who had eaten miso.” The fact that many did not have as serious health repercussions as expected was attributed to the regular inclusion of miso soup and seaweed in their diet.

Niacin
Researchers claim that niacin had been a definite point of study as an antidote to radiation exposure and has also proven to be an extraordinary effective catalyst for the discharging of radiation.
Sunflower Seeds
According to a Natural News article, both apples and sunflower seeds contain a pectin that’s adept at cleansing the body from residual radiation. (They also mention that the glucosides in buckwheat add protective measures against radiation if eaten before exposure.)
Activated Charcoal
Activated charcoal, taken internally, removes toxins and poisons from the body. In fact, it’s kept in nearly all emergency rooms at this point to help mitigate the effects of poisoning. According to WebMD, there is also some scientific evidence that it lowers cholesterol. Here’s more on how to take activated charcoal internally.
Please note, activated charcoal and charcoal briquettes are two vastly different things. Please do not eat your barbecue charcoal!
Other foods that may help in combating radiation sickness are foods that naturally detoxify the body. Foods such as reishi mushrooms, green and black teas, garlic, nettles, dandelions, ginseng, lentils, collards and mustard greens.
