Children and Nuclear Radiation 413 - Health - Fitness

After nuclear crisis in Japan, people are very sensitive about nuclear radiation. ToLearn the radiation knowledge, the public need not to worry and too much pay attention.

In the strong earthquake in Japan, Fukushima nuclear happen radioactive substances leaking events. We still not clear how long the nuclear radionuclide emissions will last. Thus, it triggers concerns from all walks of life to a nuclear disaster. Having known about radiological knowledge, the public is entirely unnecessary worry and overly concerned.

1, radiation is everywhere

In nature, there is the radiation is everywhere and we have been under natural radiation, such as cosmic rays, air, water, soil and rock, even radioactive radiation in the food and isotopes for medical diagnosis and treatment, etc. So far, the human race has discovered 109 elements, about 1,800 kind of nuclide in 1800 nuclides, only 270 kinds are stable, and the rest of more than 1,500 kinds are unstable, are radioactive isotopes. Thus it is easy to understand why our environment is full of all kinds of radiation.

2, the children are more sensitive to nuclear radiation

Fukushima nuclear radiation main threat is radioactive iodine - 131 and cesium 137 floating in the air, they spread through winds, with long distance and wide range. The human body is easy to absorb, especially children are more sensitive. Iodine is quickly absorbed by thyroid. Half-life is short only 8 days, which will disappear with radioactive decay. Cesium is absorbed by muscle, the half-life in muscles are 30 years, which means it will stay in body until it is discharged by body. Inside body, these two elements of radiation may cause serious damage, which are mainly DNA. The children which inhale radioactive iodine may in 10 years or more years later suffer from thyroid cancer; the adults seem to have resistance. To estimate Fukushima nuclear disaster health risks, the Japanese authorities have monitored radioactive iodine in childrens thyroid in the worst polluted region.

3, do not abuse potassium iodide

The research of Chernobyl nuclear events shows, thyroid is one of the most vulnerable body organs, but we can take potassium iodide to protect. Children and infants are more vulnerable than adults to suffer from thyroid cancer because of radioactive iodine. In emergency situations, we let them take, can prevent radioactive iodine absorption, and help prevent the occurrence of thyroid cancer. But we must be under the guidance of a doctor to prevent and apply. Improper application has disadvantages in healthy body.

How to protect themselves from radiation by using available tools? - Health - Medicine

In this article we introduce a variety of ways to prevent the effect of radiation in everyday life. Let's find out how to protect themselves from the effects of radiation in the zone of increased radiation.

The fact that the risk of side by side, you can find on the radio, television or on a disturbing tone of one of the companies, if any nearby residence. If you have been cut off from civilization, then you certainly will rescue a wonderful device - the dosimeter, geiger counter, which will indicate the exact level of radiation.

What if a Geiger counter indicates an increased radiation background?

How to protect yourself in an uncertain environment, or quite specific radioactive emissions?

First, keep in mind: to protect themselves from radiation is possible and necessary. Contrary to popular belief, it does not permeate through the space, affecting everyone equally. It would be fair to say that this is still happening, but it creates only 15% of the damaging effects. Also no secret that the consequences of which gives the radiation sickness, may not appear immediately, and certainly not be the same for everyone. Practice shows: even the simple methods of radiation protection can significantly reduce the negative effect.

1. In the case where the situation is uncertain, the best solution would be to retreat in the truest sense of the word. Tightly closed windows and doors will help to escape from the contaminated particles in the air and precipitation. Naturally, the imperative to give up all ventilation and air conditioning as the main supporters of the active circulation of radioactive suspensions.

2. On the street for the same purpose should be to use a gauze bandage, or, at best, a respirator. Of course, this does not reduce the impact on the body of high background radiation, but also significantly reduce the ingress of dust, particles of moisture, which concentrate the devastating effects of radiation. Also to deal with contaminated dust is often recommended to carry out wet cleaning and high-risk areas for open space - pour water.

Statistics show: 85% of the radioactive substances enter the body in the form of aerosols or steam. The main thing that directed methods of protection against radiation - is the protection of skin and respiratory system.

3. Surely, radioactive contamination, if it still exists, touched tap water. Use it should be the minimum, but if everyone did this inevitably, it is recommended to pass through a carbon filter. If it is not - at least enough to stir a tablet of activated charcoal in a glass of water, then strain it through a cloth to remove the suspension.

4. Acceptance of iodinated substances in large doses. Such drugs prevent the penetration of the thyroid gland of an infected, radioactive iodine. Suitable iodine-containing drugs are many, all will approach that includes potassium iodide. Most often it is iodine-asset and Yodomarin. Very effective iodized salt. But here we must not overdo it: excess doses of iodine can cause the body harm. In general, suitable only increased consumption of fruits and vegetables that are rich in iodine.

5. At a time when there is a danger of radioactive contamination, emphasis is beginning to play food. Many foods reduce the effects of radiation on the organism and / or increase its resistance. Some contain iodine or cesium, which prevent the penetration of the organism, respectively, radioactive iodine or cesium.

6. Pocket dosimeter can help control the level of risk and identify areas where background radiation below. At the same territory due to natural causes, this figure may fluctuate considerably, exposing a person to a greater or lesser risk.

7. Apparel suits of cotton fabrics, especially if it is pre-wetted with water. While it will dry out, then it becomes an almost insurmountable obstacle to the contaminated particulate matter. But, naturally, to resist the infection, it needs to be changed as often as possible.

Should People Take Potassium Iodide Pills to Protect Against Radiation Exposure? - Business - Industrial Mechanical

Radioactive leak in Japan has led to panic buying of iodine pills in neighboring countries such as Korea and the United States (Hawaii) which are believed to be able to prevent radiation exposure. Almost every time there is a threat of a radiation leak on the news, potassium iodide(PI) is usually mentioned as a treatment for exposure. But partly because of the lack of detailed explanations as to exactly what it does, many people may not understand its limits. Does PI really can protect people from radiation exposure?

If it happens leakage of nuclear radiation, radioactive iodine is released into the air and contaminate the local food supply. When these materials enter the body through breathing, eating or drinking, then this will lead to the condition called internal contamination.

When internal contamination occurs, the thyroid gland willquickly absorb the chemical. Radioactive iodine absorbed by the thyroid can damage the gland and can cause cancers of the thyroid cancer. Because nonradioactive KI acts to block radioactive iodine from being absorbed into the thyroid gland, it can help protect it against damage.

Will Potassium Iodide Supplements Protect People?Iodine supplements can potentially protect the thyroid gland from exposure to radioactive iodine, thyroid gland, but only it, and only if the supplement is taken before exposure. It does nothing to protect the rest of the body, and can not reverse thyroid damage against radiation once it has occurred.

Also, keep in mind that these supplements only offer limited protection against radioactive iodine. They are ineffective against other radioactive materials that may be present in the case of a nuclear release.In addition, KI also can not protect the body against other radioactive elements. So if not all radioactive iodine, KI would be ineffective to protect.

Administration and Side EffectsSupplements of PI in both tablets and liquid are usually taken once every 24 hours. And, while there are possible side effects, including the Centers for Disease Control lists on its website as "... may include intestinal, allergic reactions (possibly severe), rashes and inflammation of the salivary glands," these are usually offset by the potential benefits of taking the supplement during a nuclear crisis.

Although these supplements are not recommended for everyone. If you live in an area where the potential exists for exposure to radiation and are concerned, talk to your doctor or pharmacist to determine whether supplements of potassium iodide are good for you. And these supplements are available over the counter so no prescription is needed.

Do People Really Need These Supplements? Nuclear accidents are rare, only happens a few times since the technology was put into service. The most notable of these are probably the collapse of Three Mile Island meltdown in 1979 and Chernobyl in 1986, both of which are shown below.

But just because these accidents are rare, this does not mean they can never occur. Ultimately, whether or not you choose to have these supplements of potassium iodide on hand is up to you.
