Very high radiation, little water in Japan reactor news

TOKYO—One of Japan's crippled nuclear reactors still has fatally high radiation levels and much less water to cool it than officials had estimated, according to an internal examination that renews doubts about the plant's stability.

A tool equipped with a tiny video camera, a thermometer, a dosimeter and a water gauge was used to assess damage inside the No. 2 reactor's containment chamber for the second time since the tsunami swept into the Fukushima Dai-ichi plant a year ago.

The data collected Tuesday showed the damage from the disaster is so severe, the plant operator will have to develop special equipment and technology to tolerate the harsh environment and decommission the plant, a process expected to last decades.

The other two reactors that had meltdowns could be in even worse shape. The No. 2 reactor is the only one officials have been able to closely examine so far.

Tuesday's examination with an industrial endoscope detected radiation levels up to 10 times the fatal dose inside the chamber. Plant officials previously said more than half of the melted fuel has breached the core and dropped to the floor of the primary containment vessel, some of it splashing against the wall or the floor.

Particles from melted fuel have probably sent radiation levels up to a dangerously high 70 sieverts per hour inside the container, said Junichi Matsumoto, spokesman for Tokyo Electric Power Co. The figure far exceeds the highest level previously detected, 10 sieverts per hour, which was detected around an exhaust duct shared by No. 1 and 2 units last year.

"It's extremely high," he said, adding that an endoscope would last only 14 hours in those conditions. "We have to develop equipment that can tolerate high radiation" when locating and removing melted fuel during the decommissioning.

The probe also found that the containment vessel -- a beaker-shaped container enclosing the core -- had cooling water up to only 60 centimeters (2 feet) from the bottom, far below the 10 meters (yards) estimated when the government declared the plant stable in December. The plant is continuing to pump water into the reactor.

Video footage taken by the probe showed the water inside was clear but contained dark yellow sediments, believed to be fragments of rust, paint that had been peeled off or dust.

A probe done in January failed to find the water surface and provided only images showing steam, unidentified parts and rusty metal surfaces scarred by exposure to radiation, heat and humidity. Finding the water level was important to help locate damaged areas where radioactive water is escaping.

Matsumoto said that the actual water level inside the chamber was way off the estimate, which had used data that turned out to be unreliable. But the results don't affect the plant's "cold shutdown status" because the water temperature was about 50 degrees Celsius (122 Fahrenheit), indicating the melted fuel is cooled.

Three Dai-ichi reactors had meltdowns, but the No. 2 reactor is the only one that has been examined because radiation levels inside the reactor building are relatively low and its container is designed with a convenient slot to send in the endoscope.

The exact conditions of the other two reactors, where hydrogen explosions damaged their buildings, are still unknown. Simulations have indicated that more fuel inside No. 1 has breached the core than the other two, but radiation at No. 3 remains the highest.

The high radiation levels inside the No. 2 reactor's chamber mean it's inaccessible to the workers, but parts of the reactor building are accessible for a few minutes at a time -- with the workers wearing full protection.

Last year's massive earthquake and a tsunami set off the worst nuclear accident since Chernobyl, sending three reactor cores to melt and causing massive radiation leaks. The government said in December that the reactors are safely cooled and the plant has stabilized, while experts have questioned its vulnerability.

During a recent visit by a group of journalists including The Associated Press, the head of the plant said it remains vulnerable to strong aftershocks and tsunami, and that containing contaminated water and radiation is a challenge. Radioactive water had leaked into the ocean several times already.

Workers found a fresh leak of 120 tons from a water treatment unit this week from one of its hoses, with estimated 80 liters (20 gallons) escaping into the ocean, Matsumoto said. Officials are still investigating its impact.

Nuclear Radiation Exposure

Nuclear Radiation Exposure
Radiation exposure and radiation sickness are things to be concerned with. The United States west coast is concerned about the ongoing impacts from Japan's earthquake and on March 11, 2011 and the subsequent tsunami and now the radiation. And what about Hawaii, which is hours closer to Japan.
Those working to prevent a meltdown of the six Fukushima nuclear reactors are seriously at risk. The "Fukushima 50", as they are called have been and continue to be subjected to lethal levels of radiation exposure. Radiation sickness will lead to a quick death. Or the radiation will cause a slower death from cancer.

Even without radiation exposure, there is an increase in cancer and other diseases due to our unnatural life styles. We're eating fabricated foods. The key to better health could be as simple as eating better foods. Americans need to spend more time and money in the produce sections of the supermarket. God created foods that support the body in healing and which the human body understands how to assimilate and use. Those devoted to reducing sickness and chronic diseases, encourage us to eat more eat more fruits and vegetables.
Then there are drugs...
Often the side effects of prescription drugs designed to treat diseases, are much worse than the conditions they are curing. Many drugs merely mask the symptoms - so no real healing is taking place. The goal of some drugs is to maintain. The condition doesn't get better but it doesn't get any worse.

We have a serious world situation with the nuclear plant and radiation problems in Japan. The atmosphere is not a closed box. What happens in one part of the world can drift around the world. Fear and interest in radiation sickness and it's prevention is rising and re-kindled. The party line is that radiation levels are minor in the United States. But all nuclear radiation levels are detrimental to human health. As usual we seek a pill to fix it.
Well, good (?) news. A pill is on the way. One U.S. drug research firm, called Onconova, in collaboration with the U.S. Defense Department research laboratory, is working on such a pill. Potentially, this drug could not only protect people from dangerous levels of radiation exposure but also heal those actually exposed to damaging nuclear radiation.

Nuclear Radiation Protection

Japan's Fukushima nuclear power plant has just exploded, blasting toxic radiation into the environment. It can already beginning to be detected on the northern coast of California. - Protect yourself from deadly radiation sickness by being prepared! How you can prepare yourself and your family so you don't get sick from this Natural Zeolite will help you be protected from this deadly radiation exposure.

Ionizing Radiation, particularly from a nuclear power plant disaster is extremely hazardous to humans, animals and the environment. It is expected to hit Northern Canada and the United States in a week. What this really means is that where a lot of the whole world's food production may become contaminated with radioactive isotopes (harmful radiation), as well as the water that goes into the water supply. That means crop irrigation as well as drinking water for all those south of the mountains where the western portion of the Canada gets it drinking water. Radioactive Disease can be really harmful.

Since we cannot see, smell or taste radiation, we are dependent oGeiger Counters and Radiation Detectors  to indicate the presence of ionizing radiation. Radiation is energy traveling in the form of particles or waves in bundles of energy called photons. Some everyday examples are microwaves used to cook food, radio waves for radio and television, light, and x-rays used in medicine.
Radioactivity is a natural and spontaneous process by which the unstable atoms of an element emit or radiate excess energy in the form of particles or waves. These emissions are collectively called ionizing radiations. Depending on how the nucleus loses this excess energy either a lower energy atom of the same form will result, or a completely different nucleus and atom can be formed.
Ionization is a particular characteristic of the radiation produced when radioactive elements decay. These radiations are of such high energy that when they interact with materials, they can remove electrons from the atoms in the material. This effect is the reason why ionizing radiation is hazardous to health, and provides the means by which radiation can be detected.

The Dangers of Radiation Exposure

The frightening type of radiation exposure comes from a short-term, intense dose that causes radiation poisoning or sickness. This typically occurs due to radiation accidents. There are several different types of jobs that involve radiation and are therefore at risk for radiation poisoning, including:

• Mining or handling nuclear materials
• Working in a nuclear power plant
• Testing or working with nuclear weapons
• Nuclear pharmacists
• X-ray technicians
• Doctors who perform radiation cancer treatment, vascular embolization, etc.

Radiation is a naturally occurring form of energy that occurs in sunlight and sound waves. However, mankind has harnessed this power through nuclear materials, such as uranium, plutonium, and thorium. These materials can be utilized for weapons, electricity production, and medical devices. While radioactive materials have helped further things like clean energy and medical diagnostics, exposure to the radiation can cause serious damage to your health.

Japan's Nuclear Disaster: Radiation Symptoms Exposure & Fallout

Given below are a list of commonly seen radiation poisoning symptoms. If you or a family member or a friend are exhibiting any of these symptoms you must immediately visit a hospital and get yourself checked up.

• Nausea and vomiting
• Vomiting blood
• Excessive diarrhea
• Dehydration
• Redness, blistering, tenderness or any inflammation of skin
• Fatigue, weakness and fainting
• Hair loss
• Bloody stool
• Open sores on the skin
• Bruising and sloughing of skin
• Bleeding from the nose, mouth and the gums
• Ulceration of the esophagus, stomach or intestines
• High fever
• Slow healing of wounds

Depending on what symptoms you exhibit and in what degree, the doctor will prescribe certain medications like potassium iodide

to deal with each and every symptom. He will also try to ascertain the source of this radiation and if it is found to be an avoidable source, you must do so by all means. These radiation poisoning symptoms are a clear indicator that you have been exposed to excessive Nuclear radiation and are suffering from radiation poisoning. Corrective measures must be taken as soon as possible. The risk of cancer is also very high in people who are regularly being exposed to excessive amounts of ionized Nuclear radiation.

Effects of Nuclear Radiation exposure on the Human Body

Hair

The losing of hair quickly and in clumps occurs with radiation exposure at 200 rems or higher.

Brain

Since brain cells do not reproduce, they won't be damaged directly unless the exposure is 5,000 rems or greater. Like the heart, radiation kills nerve cells and small blood vessels, and can cause seizures and immediate death.

Thyroid

The certain body parts are more specifically affected by exposure to different types of Nuclear radiation sources. The thyroid gland is susceptible to radioactive iodine. In sufficient amounts, radioactive iodine can destroy all or part of the thyroid. By taking potassium iodide, one can reduce the effects of exposure.

Blood System

When a person is exposed to around 100 rems, the blood's lymphocyte cell count will be reduced, leaving the victim more susceptible to infection. This is often refered to as mild radiation sickness. Early symptoms of radiation sickness mimic those of flu and may go unnoticed unless a blood count is done.According to data from Hiroshima and Nagaski, show that symptoms may persist for up to 10 years and may also have an increased long-term risk for leukemia and lymphoma.

Heart

Intense exposure to radioactive material at 1,000 to 5,000 rems would do immediate damage to small blood vessels and probably cause heart failure and death directly.

Gastrointestinal Tract

Radiation damage to the intestinal tract lining will cause nausea, bloody vomiting and diarrhea. This is occurs when the victim's exposure is 200 rems or more. The radiation will begin to destroy the cells in the body that divide rapidly. These including blood, GI tract, reproductive and hair cells, and harms their DNA and RNA of surviving cells.

Reproductive Tract

Because reproductive tract cells divide rapidly, these areas of the body can be damaged at rem levels as low as 200. Long-term, some radiation sickness victims will become sterile.
