Facts About Acute Radiation Syndrome

Written By Luthfie fadhillah on Rabu, 16 Maret 2011 | 01.07

Nuclear power plant in Fukushima Daiichi operated Tokyo Electric Power Co (Tepco) dillaporkan leaking. Concerns about the dangers of radiation have prompted the Japanese government made a number of preventive efforts, including evacuating 170,000 people who live in the area in a radius of 20 kilometers from the location of nuclear power plants. How bahayakah exposure to nuclear radiation?

Based on the Center for Disease Control and Prevention in the U.S., acute radiation syndrome or Acute Radiation Syndrome (ARS), also known as radiation poisoning, is a serious disease. This can occur shortly after the body exposed to radiation. The level of suffering a person to radiation depends on how the amount of radiation absorbed by the body. Here are some facts regarding the acute radiation syndrome:

    * Someone said to suffer from acute radiation syndrome when radiation is absorbed into the internal organs. Radiation from X-rays and medical measures such as CT-scan was too low to cause a person exposed to acute radiation syndrome.
    * Someone said to suffer from acute radiation syndrome when he was exposed to radiation for some time. It could be in minutes.
    * Early symptoms can be felt a few minutes to several days after a person is exposed to radiation. These symptoms may include vomiting, diarrhea, and drunk or dizzy. These symptoms can take up a matter of days.
    * After the initial symptoms disappear, someone back in shape. However, shortly thereafter, the person will suffer again. In fact, this time worse. Symptoms may include fatigue, fever, loss of appetite, vomiting, and diarrhea. This stage can last for several months.
    * Damage to the skin due to radiation can occur within hours. This can last up to a matter of years, depending on how severe the person is exposed to radiation. The symptoms, skin feels sore and even feels like a burn. Hair loss can be due to radiation.
    * Exposure to radiation may lead to death, depending on severity. Typically, in many cases, death occurred several months after a person is exposed to radiation. Deaths caused by damage to bone marrow, infection, or bleeding.
    * Someone who survived the acute radiation syndrome can continue to feel the symptoms until two years after exposure.
    * The treatment is done for a person exposed to radiation consists of an act of prevention of further contamination, reduce the symptoms of the syndrome, and the healing of organs damaged by radiation.
    * Decontamination is the process of eliminating external contamination by radioactive particles. Decontamination can be off all clothes and shoes that used a person exposed to radiation. Body wash can also reduce the external contamination.

Japan Nuclear Risk Low

The experts said the health risk posed by the explosion of Japan's nuclear reactor is assumed to be low, and even if the winds carry contaminants into the Pacific region, it would not threaten other countries.

Japan is currently working to fix leaks in the three-reactor nuclear power plant in Fukushima, following the tsunami by an earthquake measuring 8.9 magnitude on Friday last.

However, amid fears of neighboring countries and regions in the rest of Asia will be the impact of radiation on the wind, the United Nations through one of its officials assert that the risk of the spread of radiation is still fairly low.

"This is not a public health problem. It will not be like Chernobyl," said Malcolm Crick, Secretary of the United Nations Scientific Committee on Atomic Radiation Field Effects as quoted by Reuters.

As a precautionary measure, the Government of Japan has about 140,000 people evacuated from the area around the reactor in Fukushima.

Crick give an idea, a leak at Three Mile Island nuclear reactor, U.S., in 1979 - which is more severe on an international scale than the events in Japan-issued low-level radiation.

"A lot of people expected to be exposed to radiation after the Three Mile Island. The level of radiation can be detected, but in the context of human health does not mean anything," said Crick.

World Health Organization (WHO) also states that public health risks due to leakage of Japanese nuclear power plant remains in scale "quite low".

Meanwhile, Japan's Meteorological Agency reported that the winds in the area of ​​the reactor moves from south to west on Sunday night, or blowing from Fukushima to the Pacific Ocean.

"The direction of prevailing winds to the community in Japan. Wafts toward the Pacific. But I do not think it would be a problem for other countries," said Lennart Carlsson, Director of Security of Nuclear Power in Sweden.

Chernobyl event known after radiation was detected at Forsmark nuclear plant in Sweden, more than a day after the explosion, in which Moscow party has never officially acknowledged the incident.

Crick stated, time is very helpful in suppressing the leakage risk to health because of the adverse effects of radiation such as radio iodine to disappear in a matter of hours or days.

The Japanese themselves assess the events in Fukushima is at level 4 on an international scale, which means the only cause localized impacts. While the events of Chernobyl is at its highest level, namely the scale 7, and the case at Three Mile Island was in level 5.

Concerned About Nuclear Explosion

The explosion damaged Unit 1 reactor containment sparked great panic among residents. Approximately 180,000 people residing in a radius of 20 km from the NPP also ask evacuated.

In a press conference Nuclear and Industrial Safety Agency of Japan (NISA) followed Dahono Fitrianto Kompas journalist at the Foreign Press Center in Tokyo, Monday night, causing an explosion similar to an explosion of Union, namely the high concentration of hydrogen gas inside the reactor due to the failure of reactor coolant system .

"The explosion because the concentration of hydrogen to break down the concrete structure which protects the reactor with the same process as in Unit I. Protective layer of the reactor is still functioning, "the statement NISA.

Contaminated

Residents panic increased primarily due to explosion of Unit 1 led to 22 people and 190 people contaminated by radiation exposure. Japanese public opinion, the worst nuclear disaster at Chernobyl in April 1986, may be repeated in Fukushima. It raises new panic tsunami victims.

Fear of causing things worse, some countries in Europe asked its citizens consider to leave Japan. Dozens of foreigners began to leave Japan on Monday, shortly after the explosion at Unit 3.

Various international reaction to respond to the second blast, which was also accompanied by loss of cooling capacity at Unit 2. This indicates that the nuclear danger more real could threaten safety. U.S. has attracted the USS Ronald Reagan aircraft carrier off the coast of Japan for fear of being exposed to nuclear reactions.

Aircraft carrier that was docked at 160 kilometers off the coast of Japan that detects the radiation from the Fukushima nuclear power plant. U.S. officials say, his presentation may be equivalent to one month exposure to natural radiation. Therefore, the ship pulled further out.

U.S. aircraft in flight carrying relief supplies to disaster areas Japan was withdrawn. Shortly after the explosion, the U.S. Seventh Fleet ships and aircraft pulled away.

French Government to act more firmly again. Citizens are encouraged to get out of Japan within the next few days if they have no special reason to survive. France also warns that if the nuclear reactor exploded, radioactive dust could reach Tokyo in a few hours.

Austria also warned its citizens to leave Japan. "A third of our staff has gone from Tokyo," said EU officials in Japan, Stefan Huber. A number of German corporate executives, such as Bosch, Daimler, and BMW, to evacuate his family.

Harmless

NISA said there was no possibility of a nuclear crisis similar to the Chernobyl nuclear power plant in Fukushima following a hydrogen explosion. Minister of National Strategy of Japan Koichiro Genba told Jiji Press said Japan will not experience a case like Chernobyl.

Cabinet Secretary Yukio Edano said it had received reports that a second explosion, but it does not damage the explosion of hydrogen and reactor. Disturbance in the NPP is still within safe limits, not dangerous.

NISA parties assert, the protective layer of the reactor was still intact, there is no radiation hazard, contamination, and the explosion in reactor. "There is no risk of hydrogen explosion because there is no oxygen in the protective layer. During the residents to evacuate as ordered, there would be no effect on human health, "the statement NISA.

Radiation levels measured near the reactor, Monday at 13:12, at 34.2 microsievert per hour. For comparison, the rate of abdominal radiation X-ray examination with X-rays at the hospital reached 600 microsievert. A person traveling on an airplane go-home from Japan to U.S. East Coast will receive $ 200 microsievert radiation.

Radiation levels were well below the radiation measured at the Unit 1 reactor that exploded last Saturday. Measurement of radiation levels in the reactor building fence early Monday showed the number 680 microsievert per hour.

According to Japanese Prime Minister Naoto Kan, a situation that troubled nuclear reactor earthquake is still alarming. The authorities have done an effort to prevent widespread damage. Officials confirm, three nuclear reactors in northern Tokyo overheating, raising fears of radiation occur.

Japan faces three at a time of disaster: earthquakes, tsunamis, and now a nuclear threat.

Condolences RI

President Susilo Bambang Yudhoyono on Monday, said the Indonesian government and people express deep condolences and sympathy to the government and people of Japan. Government attempts to provide assistance to the Japanese. On the other hand, the government is also trying to save the citizens of Indonesia (WNI) that also became victims.

"We understand what the Japanese people felt because we also experienced a similar calamity in 2004. Communication with Japan in the last three days have not received an explanation about what we can do for you, but decided dispatch a contingent to provide assistance, "the president said.

Executive Director of Migrant Care Anis Hidayah asked the government to ensure the presence of 75,000 Indonesian migrant workers in Japan. So far there are 25,000 only call the Embassy of citizens in Japan.

Already Radiation Levels Threatening

The level of radiation near a nuclear power plant damaged by an earthquake in Japan is now dangerous for human health. The Japanese government submitted it after two explosions and fires at the facility,

"There is no doubt that unlike in the past, the numbers already are at levels where human health may be affected," said chief Japanese government spokesman Yukio Edano.

Tens of thousands have been evacuated from an existing zone within a radius of 20 kilometers from the Fukushima No. generators. 1, 250 kilometers northeast of Tokyo. However, Prime Minister Naoto Kan urged people who live within 10 kilometers of the exclusion zone around the plant to stay indoors.

Tuesday morning, an explosion occurred at reactor number two in these plants. Edano later said there was also an explosion that sparked a fire at reactor number four. Although the number four reactor shut down for maintenance when the earthquake and tsunami struck on Friday, "Spent nuclear fuel in the reactor was heating up, creating hydrogen and trigger a hydrogen explosion."

He said the leak of radioactive material together with hydrogen. "Keep in mind that what was burning was not the nuclear fuel itself," said Edano. "We will do our best to extinguish or control the fire as soon as possible."

Similar hydrogen explosion has damaged reactor number one and number three on Saturday and Monday. The buildings for four of six reactors at the plant, which operated in 1971, has now been damaged by the explosion.

Edano said the radioactive material may have spread in the area about 20-30 kilometers. However, these substances will disappear when it spreads even further.

Japan is now struggling to cope with nuclear emergency conditions after a devastating earthquake and tsunami on Friday cut off the electricity to power the 40-year-old and thwart the cooling system. The officers have been struggling to prevent leakage of the damaged reactor. They said the fuel rods may have been damaged due to overheating.

Nuclear crisis has been created by the people in the surrounding area, who are still fighting the post-earthquake and tsunami, so unnerved. "There are very few people out on the streets," said Mako Sato, a maid cafe in town Miharumachi, just outside the evacuation zone. "They live at home or in evacuation centers due to conditions in the vicinity of nuclear power is uncertain. Supplies of food less and all the customers talk about earthquakes and how scary it is because we are still feeling the aftershocks."

An employee at the Chisun Hotel Koriyama said, there were no signs of panic despite the nuclear crisis. "Everyone is calm. But because there are security concerns after the earthquake, we do not accept new business," said the employee. "Food is very little. Convenience store nearest them closed. We do our best with the service we got."

Dangers of Nuclear Radiation on Health

After the big earthquake in Japan, public fears of impending nuclear explosion on Nuclear Power Plant reactor Fukushima, Japan. The fear was probably justified given the effects of radiation on the body can not be taken lightly.

Impact of radiation according to Dr. David J. Brenner, director of the Center for Radiological Research at Columbia University, is not straightforward. "Could weeks and then new symptoms appear," he said.

He mentioned the impact of radiation on the body depends on the radioactive material is released and the duration of exposure. Exposure to high levels can cause acute radiation syndrome, even death. Syndrome will cause symptoms of nausea, vomiting, fatigue, hair loss, and diarrhea.

At higher levels, victims who are exposed can die within weeks. "The reason is that scorched colon," he said.

Nuclear radiation will disrupt the ability of cells to divide and produce. The cells in the large intestine is usually a part of the body most rapidly dividing. Similarly, blood-forming cells in bone Sumsung highly susceptible to radiation.

Meanwhile, the population included in the low risk group, nuclear radiation can trigger cancer risk in recent years. However, it also depends on the length of exposure and type of radioactive spent nuclear reactor.

Some types of radioactive material there which is easily absorbed by the body and survive. For example, the iodine that will be directly absorbed by the thyroid gland or strontium which will enter the bone. Other types of radioactive, such as tritium, will be quickly removed the body.

To avoid radiation danger, the Japanese government has given potassium iodine pills that can neutralize the influence of iodine was a way to prevent the thyroid gland to absorb iodine. But according to Brenner, iodine can enter the human body through various ways, ie, air or food exposed to radiation.

"Radioactive iodine should not get into your body directly. Iodine that is in the air can be absorbed into the soil and livestock eat the grass where the land is exposed to radiation. Then humans eat the meat or milk that cow," he said.

He therefore argues idodide potassium pills less effective in preventing thyroid cancer due to nuclear radiation. "The epidemic of thyroid cancer in Chernobyl nuclear casualties could be prevented if the government immediately banned its citizens to drink cow's milk or eat a fruit that grows from the soil exposed to radiation," he said.

Children aged less than 18 years, infants, and fetuses in the womb is the group most at risk of exposure to radiation because the cells in their bodies are still actively dividing.

What amounted to a Dangerous Radiation

Anxiety about the impact of radiation on the health of the nuclear reactor explosion Fukushima appeared in various countries. But the concern did not seem to have excessive levels of radiation is at risk if health is understood by the public.

Here are are some facts you need to know about the amount of radiation exposure and the threat to health. This data is sourced from the World Nuclear Association.

* To calculate how much radiation exposure to humans in their daily life and to know its potential impact on health, imposed a kind of measurement units. One measure is the Sievert (Sv), which is used for radiological protection standards.

The unit of measurement is applied to calculate the biological effects of radiation type or different. For doses in humans, commonly used measurement is millisieverts (mSv), or one thousandth of Sievert.

* Head of the Japanese Government spokesman Yukio Edano said radiation levels near the reactor that exploded to 400 millisieverts (mSv) per hour, or thousands of times higher than before the explosion. But then, this number is corrected value becomes lower. Radiation levels of 400 mSv is equivalent to 20 times per year of exposure experienced by workers in nuclear reactors or uranium mines.

* Exposure to 350 mSv is the criteria or conditions used in the World Nuclear Association to relocate the residents after the Chernobyl explosion.

* Any natural person may be exposed to radiation of about 2 mSv per year.

* The procedures for the use of X-ray beam on the chest of patients presenting 0:02 mSv, whereas in the teeth just reach mSv 00:01

* Crew of aircraft assigned to the New York-Tokyo route could be exposed to 9 mSv per year.

* Exposure to radiation sebasar 100 mSv is the lowest level that can increase the risk of cancer. Cumulative exposure of 1.000 mSv likely to cause fatal cancer after a period of many years in 5 of 100 people exposed to radiation.

* The dose of 1,000 mSv exposure can cause immediate effects such as nausea but does not cause death. Dose of 5,000 mSv bsia cause death within a month interval in 50 percent of people exposed to radiation.

* Lam Ching-wan, a chemical pathologist from the University of Hong Kong believes the radiation that is very acute, as happened at Chernobyl and that befall the nuclear power plant workers in Japan, less likely to occur in the population.
