The Radiation Issue
In light of the past nuclear power plant accidents, the possible future ones, and the constant seepage of radioactive debris into the ocean from Fukushima, I concluded radiation protection is something we all need to know about.
In addition, some people with cancer use radiation to kill the cancer cells, which can lead to additional oxidative damage, and other cancers down the road. Therefore, knowing how to protect from, or mitigate radiation damage is especially useful for these individuals.
Don't Go Overboard
Be prepared if you are concerned, but don’t start worrying about radioactive iodine, or ingesting iodine until you are sure there is enough danger that you need it. Ingesting too much iodine is dangerous, so don't do it unless necessary, and you know what you are doing. Seek health care guidance from a professional. Later in this article, iodine will be examined closely.
Radiation Exists Naturally
We have a certain amount of radiation around us all the time, both natural and that due to human creation. Therefore, the most prudent thing to do is stay as healthy as possible at all times.
Herbs To Consider
The results obtained from in vitro and in vivo studies indicate that several herbs protect against radiation-induced lethal dosages, lipid peroxidation and DNA damage.
- Ginkgo - Gingko biloba
- Gotu kola - Centella asiatica,
- Seabuckthorn - Hippophae rhamnoides
- Holy Basil - Ocimum sanctum
- Ginseng - Panax ginseng,
- Amaranth - Amaranthus paniculatus
- Indian gooseberry - Emblica officinalis
- Stonebreaker - Phyllanthus amarus
- Long pepper - Piper longum,
- Guduchi - Tinospora cordifoila
- Wild Mint - Mentha arvensis
- Peppermint - Mentha piperita
- Jambul - Syzygium cumini
- Ginger - Zingiber officinale
- Billy goat weed - Ageratum conyzoides
- Bengal quince - Aegle marmelos
- Pithraj tree - Aphanamixis polystachya
Ginkgo was shown to be protective against radiation-induced injuries following the Chernobyl disaster. Treatment of recovery workers from the Chernobyl accident site was found to be effective when an oral dose of 40 mg/day of G. biloba EGb 761 extract was given 3 times daily for 2 months.
It appears that Antioxidants are protective against radiation. In fact the clastogenic factors found in the blood of people exposed to radiation have been shown to be related to oxidatve stress. Therefore, antioxidants can be of benefit to anyone around radioactive material. Reduction of transient free radicals is one mechanism by which antioxidants influence the indirect action of radiation. The extent of danger to normal tissues in radiation therapy for cancer depends on the dose, tissue sensitivity and repair capacity, affected organs, and prevailing endogenous antioxidant defenses.
Short- and long-term injury to healthy cells, including tissue damage and increased risk of oncogenic (cancer forming) transformation, can be prevented by antioxidants, as seen experimentally. Antioxidants induce apoptosis in cancer cells and protect patients from painful side effects of radiation treatment for cancer. It appears antioxidants are also useful in radiation from nuclear power plant accidents. For more information like this go to http://jn.nutrition.org/content/134/11/3207S.full

We Should All Be Concerned About Nuclear Reactors
Everyone on the planet should be concerned about the reactors that spewed radioactive substances into the sea, and air in the past. The Japanese reactors that failed, hold about 1,000 times more radiation than the bombs dropped over Hiroshima, and it is still seeping radiocative waste into the ocean.
The Effects Of Nuclear Reactor Breakdows Are Felt All Over The World
These incidents affect the whole world. I am far from Japan in the United States, but the prevailing jet stream winds are blowing from Japan directly across the Pacific ocean to the west coast of the United States. Any airborne radioactive fallout would make its way across with the jet stream, reaching the U.S. in approximately 36 hours, depending on the actual speed of the jet air stream and how quickly the particles mixed in with the jet-stream. In the spring season when Fukushima melted down, the jet stream moves eastward from Japan toward the United States. Heated isotopes, riding on a cushion of steam and oceanic updrafts, will rise to the west-east jet stream at altitude 20,000 feet or higher. Areas of radioactive fallout are difficult to predict since these depend on local wind currents, temperatures, rainfall and other factors. The jet stream will cross the following states: California, Oregon, Montana, Idaho, Nevada, Colorado, Wyoming, Nebraska, the Dakotas, Iowa, Wisconsin, Illinois and possibly further depending on surface winds. Cesium can be expected to fall unevenly, so monitoring would be vital to determine the long-term threat level. (A week after a nuclear weapons test in China, iodine 131 could be detected in the thyroid glands of deer in Colorado, although it could not be detected in the air or in nearby vegetation.) Unfortunately, our government did everything it could to downplay the incident and ignore it. At least that is what they told us. "Nothing to see here kids, go home."
Radiation Has Many Effects
Radiation can affect the body in a number of ways, and the adverse health effects of exposure may not be apparent for many years. These adverse health effects can range from mild effects, such as skin reddening, to serious effects such as cancer and death, depending on the amount of radiation absorbed by the body (the dose), the type of radiation, the route of exposure, and the length of time a person was exposed. Exposure to very large doses such as would happen if near a nuclear explosion may cause death within a few days or months. Exposure to lower doses of radiation may lead to an increased risk of developing cancer or other adverse health effects later in life. These lower doses are what people on the West Coast of the U.S. were worried about when Fukushima melted down and some still have concerns about. Don't forget Fukushima continues to leach into the ocean even now, years later.
Nuclear Reactors Have A Shelf Life
Our nuclear reactors are all getting old and there is no plan for what to do when they are past their prime. We have no safe way to dispose of the waste from the reactors. They were a bad idea in the beginning and still a bad idea.
If you are around radioactive fall-out
If you are around radioactive fall-out what should you do? Radiation can go through material depending on its density.
- Close all doors and windows.
- Turn off fans, air conditioners, and forced-air heating units that bring in fresh air from the outside. Only use units to recirculate air that is already in the building.
- Close fireplace dampers.
- Bring pets inside.
- Move to an inner room or basement. The deeper in the earth or behind dense material such as concrete or metal, the better.
What radioisotopes should we be concerned about.
Lets look at Chernobyl: As of 2005, cesium-137 (C-137) is the principal source of radiation in the zone of alienation around the Chernobyl nuclear power plant. Together with cesium-134, iodine-131, and strontium-90, caesium-137 was among the isotopes with greatest health impact distributed by the reactor explosion.
It appears the main radioisotopes of current concern is Strontium-90 (s-90), Iodine-131 (I-131), and Cesium-134 and 137 (C-134&137). I-131 has a half life of 8.06 days. It can be inhaled, absorbed through the skin or ingested in food or water. http://en.wikipedia.org/wiki/Iodine-131
C-137 has a half-life of about 30.17 years, and decays by beta emission to a metastable nuclear isomer of barium-137. http://en.wikipedia.org/wiki/Caesium-137
What does the CDC say?
I know you wonder if you can expect good advice from them, but ...
There is not much you can do ahead of time for C-134 &137radiation. The FDA has determined that the 500 mg Prussian blue capsules,(Radiogardase) can be safe and effective for the treatment of known or suspected internal contamination with radioactive cesium, radioactive thallium, or non-radioactive thallium. This decision is based on a careful review of published literature articles containing reports, data, and experiences of people who were exposed to high levels of thallium or cesium-137 and were treated effectively with Prussian blue.
Prussian blue should be taken as soon as possible after exposure. However, even when treatment cannot be started right away, patients should be given Prussian blue as soon as it becomes available because it is still effective even after time has elapsed since exposure.
Prussian blue is available only by prescription and should be given only under the supervision of a physician after assessing your medical condition. It is only effective to treat contamination with radioactive cesium or thallium. The dose and duration of treatment depends on the amount of contamination a person is exposed to. Therefore, this drug should be given only when the physician has determined your need for it.
I don’t know of any direct treatments for strontium-90 exposure.
External exposure to large amounts of I-131 can cause burns to the eyes and on the skin. Internal exposure can affect the thyroid gland. The thyroid gland uses iodine to make thyroid hormones and cannot distinguish between radioactive iodine and stable (nonradioactive) iodine. In addition, if dairy animals consume grass contaminated with I-131, the radioactive iodine will be incorporated into their milk. Consequently, people can receive internal exposure from drinking the milk or eating dairy products made from contaminated milk. Once inside the body, I-131 will be absorbed by the thyroid gland exposing it to radiation and potentially increasing the risk for thyroid cancer or other thyroid problems. http://www.bt.cdc.gov/radiation/isotopes/iodine.asp
For those people who were exposed to radioactive I-131 from 1945-1962 in the United States, there is a website that you might want to check out here: https://www.atsdr.cdc.gov/hec/csem/iodine/docs/iodine131.pdf
Following a radiological or nuclear event, radioactive iodine may be released into the air and then be breathed into the lungs. Radioactive iodine may also contaminate the local food supply and get into the body through food or through drink. When radioactive materials get into the body through breathing, eating, or drinking, we say that “internal contamination” has occurred. In the case of internal contamination with radioactive iodine, the thyroid gland quickly absorbs this chemical. Radioactive iodine absorbed by the thyroid can then injure the gland.
How I Support My Thyorid
As far as protecting my thyroid from radioactive iodine that may be at low levels among us, I personally eat kelp daily. All sea vegetables contain iodine and other minerals. Kelp does not give you the CDC's recommended amount of iodine if your exposed to radioactive fallout. So if that does happen you will want to use the recommendation of the CDC below.
Ingestion of Potassium iodide (KI)
Because ingestion of non-radioactive KI acts to block radioactive iodine from being taken into the thyroid gland, it can help protect this gland from injury.
KI cannot prevent radioactive iodine from entering the body. KI can protect only the thyroid from radioactive iodine, not other parts of the body. KI cannot reverse the health effects caused by radioactive iodine once damage to the thyroid has occurred. KI cannot protect the body from radioactive elements other than radioactive iodine—if radioactive iodine is not present, taking KI is not protective.
Iodine ingestion is undertaken to keep I-131 from binding to the thyroid tissues. Some people react to potassium iodine and they should not take this form. Check with your doctor about any concerns you have about potassium iodide. Potassium iodide is the most common form of iodine available on the market.
Potassium iodide (also called KI) is a salt of stable (not radioactive) iodine. Iodine needed by the body to make thyroid hormones. Most of the iodine in our bodies comes from the food we eat. KI is stable iodine in a medicine form.
KI works by blocking radioactive iodine from entering the thyroid. When a person takes KI, the stable iodine in the medicine gets absorbed by the thyroid. The thyroid gland becomes “full” and cannot absorb any more iodine—either stable or radioactive—for the next 24 hours.
Iodized table salt also contains iodine; iodized table salt contains enough iodine to keep most people healthy under normal conditions. However, table salt does not contain enough iodine to block radioactive iodine from getting into your thyroid gland. You should not use table salt as a substitute for KI. In fact if you eat a big dose of table salt, it could kill you before the radiation would.
Knowing that KI may not give a person 100% protection against radioactive iodine is important. How well KI blocks radioactive iodine depends on
- How much time passes between contamination with radioactive iodine, and the taking of KI (the sooner a person takes KI, the better), how fast KI is absorbed into the blood.
- The total amount of radioactive iodine to which a person is exposed.
In Radiation Exposure, who should take KI according to the CDC & How Much?
This is taken from the CDC at this link but it is no longer active. http://www.bt.cdc.gov/radiation/ki.asp#howmuchki
The thyroid glands of a fetus and of an infant are most at risk of injury from radioactive iodine. Young children and people with low stores of iodine in their thyroid are also at risk of thyroid injury.
Infants (including breast-fed infants): Infants need to be given the recommended dosage of KI for babies. The amount of KI that gets into breast milk is not enough to protect breast-fed infants from exposure to radioactive iodine. The proper dose of KI given to a nursing infant will help protect it from radioactive iodine that it breathes in or drinks in breast milk. Infants and children between 1 month and 3 years of age should take 32 mg (½ of a 65 mg tablet OR ½ mL of solution). This dose is for both nursing and non-nursing infants and children. Newborns from birth to 1 month of age should be given 16 mg (¼ of a 65 mg tablet or ¼ mL of solution). This dose is for both nursing and non-nursing newborn infants.
Children: The United States Food and Drug Administration (FDA) recommends that all children internally contaminated with (or likely to be internally contaminated with) radioactive iodine take KI, unless they have known allergies to iodine. Children from newborn to 18 years of age are the most sensitive to the potentially harmful effects of radioactive iodine. Children between 3 and 18 years of age should take 65 mg (one 65 mg tablet OR 1 mL of solution). Children who are adult size (greater than or equal to 150 pounds) should take the full adult dose, regardless of their age.
Young Adults: The FDA recommends that young adults (between the ages of 18 and 40 years) internally contaminated with (or likely to be internally contaminated with) radioactive iodine take the recommended dose of KI. Young adults are less sensitive to the effects of radioactive iodine than are children.
Pregnant Women: Because all forms of iodine cross the placenta, pregnant women should take KI to protect the growing fetus. However, pregnant women should take only one dose of KI following internal contamination with (or likely internal contamination with) radioactive iodine.
Breastfeeding Women: Women who are breastfeeding should take only one dose of KI if they have been internally contaminated with (or are likely to be internally contaminated with) radioactive iodine. Because radioactive iodine quickly gets into breast milk, CDC recommends that women internally contaminated with (or are likely to be internally contaminated with) radioactive iodine stop breastfeeding and feed their child baby formula or other food if it is available. If breast milk is the only food available for an infant, nursing should continue. Women who are breastfeeding should take the adult dose of 130 mg.
Adults: Adults older than 40 years should not take KI unless public health or emergency management officials say that contamination with a very large dose of radioactive iodine is expected. Adults older than 40 years have the lowest chance of developing thyroid cancer or thyroid injury after contamination with radioactive iodine. They also have a greater chance of having allergic reactions to KI. Adults should take 130 mg (one 130 mg tablet OR two 65 mg tablets OR two mL of solution).
How much KI should I take?
The FDA has approved two different forms of KI—tablets and liquid—that people can take by mouth after a nuclear radiation emergency. Tablets come in two strengths, 130 milligram (mg) and 65 mg. The tablets are scored so they may be cut into smaller pieces for lower doses. Each milliliter (mL) of the oral liquid solution contains 65 mg of KI.
According to the FDA, the following doses are appropriate to take after internal contamination with (or likely internal contamination with) radioactive iodine:
How often should I take KI?
A single dose of KI protects the thyroid gland for 24 hours. A one-time dose at the levels recommended in this fact sheet is usually all that is needed to protect the thyroid gland. In some cases, radioactive iodine might be in the environment for more than 24 hours. If that happens, local emergency management or public health officials may tell you to take one dose of KI every 24 hours for a few days. You should do this only on the advice of emergency management officials, public health officials, or your doctor. Avoid repeat dosing with KI for pregnant and breastfeeding women and newborn infants. Those individuals may need to be evacuated until levels of radioactive iodine in the environment fall.
Taking a higher dose of KI, or taking KI more often than recommended, does not offer more protection and can cause severe illness or death.
Medical conditions that may make it harmful to take KI
Taking KI may be harmful for some people because of the high levels of iodine in this medicine. You should not take KI if
- you know you are allergic to the type of iodine used.
- you have certain skin disorders (such as dermatitis herpetiformis or urticaria vasculitis).
People with thyroid disease (for example, multinodular goiter, Graves’ disease, or autoimmune thyroiditis) may be treated with KI. This should happen under careful supervision of a doctor, especially if dosing lasts for more than a few days.
In all cases, talk to your doctor if you are not sure whether to take KI.
What are the possible risks and side effects of KI?
When public health or emergency management officials tell the public to take KI following a radiologic or nuclear event, the benefits of taking this drug outweigh the risks. This is true for all age groups. Some general side effects caused by KI may include intestinal upset, allergic reactions (possibly severe), rashes, and inflammation of the salivary glands.
When taken as recommended, KI causes only rare adverse health effects that specifically involve the thyroid gland. In general, you are more likely to have an adverse health effect involving the thyroid gland if you
* take a higher than recommended dose of KI,
* take the drug for several days, or
* have pre-existing thyroid disease.
Newborn infants (less than 1 month old) who receive more than one dose of KI are at particular risk for developing a condition known as hypothyroidism (thyroid hormone levels that are too low). If not treated, hypothyroidism can cause brain damage. Infants who receive KI should have their thyroid hormone levels checked and monitored by a doctor. Avoid repeat dosing of KI to newborns.
