Foods and homeopathy offer excellent choices to protect us and rid our bodies from radiation - not just nuclear, but also medical radiation and exposure during long flights.
Natural nuclear radiation protection is especially important for young children or people who have an autonomously functioning thyroid nodule, as the recommended large dose of Potassium Iodine can precipitate a thyroid crisis. 
The reason why potassium iodine is recommended in case of a nuclear disaster is because if you are deficient in iodine, the body will suck radiactive iodine into the thyroid gland. The body does not distinguish between regular and radioactive iodine. However, potassium iodine only protects your thyroid for one to three days, and prolonged use of large doses of potassium iodine increases the risk of endocrine imbalances. Plus it does nothing to protect you from detoxifying the radiation.
It is important to take adequate amounts of iodine from safe sources on a regular basis to have adequate iodine stores. This will not only protect you from radioactive iodine but also from environmental toxins that can poison your thyroid gland like fluoride, bromine and chlorine. 
Toxin-free sea vegetables such as dulse, kelp and kombu are an ideal way to obtain your iodine and other essential minerals. However, prudence is urged. Dr. Brownstein sent out sea vegetable samples to labs and found that most of them were contaminated with heavy metals and had bromine instead of iodine. Only organic versions that have been screened for radioactivity and heavy metals by an independent third party and passed.
Chlorella, Spirulina and other high-chlorophyll foods are essential in ridding the body of any radiation. According to Brian Clement, PhD from the Hippocrates Health Institute, Chlorella is the most effective as it has a mineral complex that magnetizes toxins and acts as a sponge to soak them up. Russian research scientists confirmed, that the combination of chlorella and chlorophyll proved to be highly effective to rid victims of the Chernobyl disaster from radioactivity. 
Scientific studies have shown that homeopathy is effective for detoxing from all kinds of radiation, including radiation exposure from long flights and medical procedures. [4,5,6] Homeopathic Remedies are safe for all ages, cost-effective and - if stored correctly - do not expire.
A nuclear protection protocol to have on hand is a trio of homeopathic remedies: Kali Iodatum 6c (which is Potassium Iodine), Radium Bromatum 200c and X-Ray 200c.
I offer the Nuclear Radiation Protection Package for $ 29.95 (including sales tax). Remedies are also available individually.
To order just email me at firstname.lastname@example.org or call 310-801-4288, and I will deliver/send it to you.
You can also take one does of the homeopathic X-Ray remedy before you fly or are in need of a CAT scan or X-Ray to protect the body.
Protect Yourself from Radiation .... Naturally ;-)
