BOM atom has destroy cities Hiroshima and Nagasaki 65Th ago, that dark period in the country called the Sun's state, it took several decades to build a city destroyed by the atomic bomb weapons of mass destruction at the time, now that the country's development 65Th very japanese different, and not expected to be one influential country in the world, both in technology and also not leave the indigenous cultures that coexist in harmony.
March 11, 2011 Japan experienced BOM Atom second time this time in the form of a magnitude 9 earthquake and tsunamis devastating SR, destroy back some of the country. The impact of the earthquake that occurred Friday March 11, 2011 one of which gives the impact of radiation due to explosion of a nuclear power plant in Fukushima is now alarming. Radioactive contamination can cause human health problems. Like what are the effects of radiation?
Japan's new danger threatens the Earth with a tsunami after the earthquake. That's because some nuclear power plants (NPP) in Japan were damaged. The threat of radioactive contamination hazards to surface eventually. Is a kind of radioactive substance that is on the surface or in a solid, liquid or gas whose presence harmful to human body. Radioactive comes from radionuclides (radioisotopes), an unstable nucleus due to excessive energy.
There are at least seven harmful effects human body when exposed to radioactive leaks from nuclear power plants. Effects can be harmful to the hair, organs such as brain, heart, gastrointestinal tract, thyroid gland, circulatory system, and reproductive tract, following some impact from the effects of radioactivity on the human body are:
1. Hair.
Effects of radioactive exposure makes the hair will disappear quickly when exposed to radiation at 200 Rems or more. Rems is a unit of radioactive strength.
2. Brain.
Brain cells will not be damaged directly unless exposed to radiation measuring Rems 5000 or more. Like the heart, radiation kills nerve cells and blood vessels and can cause seizures and sudden death.
3.Mumps gland.
The thyroid gland is very susceptible to radioactive iodine. In certain amount, radioactive iodine can destroy part or all of the thyroid.
4. Circulatory System.
When a person is exposed to radiation of about 100 Rems, blood lymphocyte count would be reduced, making the victim more susceptible to infection. The initial symptoms resemble flu-like illness. According to the data when there was an explosion of Nagasaki and Hiroshima, showed symptoms can last for ten years and may have long-term risks such as leukemia and lymphoma.
5. Heart.
If someone is exposed to radiation measuring Rems 1000 to 5000 will result in direct damage to blood vessels and can lead to heart failure and sudden death.
6. Digestive tract. Radiation with a power of 200 Rems will cause damage to the lining of the intestinal tract and can cause nausea, vomiting and bloody diarrhea.
7. Reproductive tract.
Radiation can damage the reproductive tract with enough power under 200 Rems. In the long term, radiation victims will experience infertility.
Seeing the danger of radioactive radiation impact of this, the Japanese government immediately set a high alert following a potential radioactive leaks at five nuclear reactors at two locations. Three thousand residents who live around the Fukushima Daiichi nuclear reactor with a radius of 10 km immediately evacuated.
As many as 14,000 people living in the northeastern part of Japan are still on site and Daiichi, helped also evacuated after receiving a warning from the Tokyo Electric Power Co.. Japan has 54 reactors and 10 of them have been closed related to the earthquake and tsunami disaster that struck the region. About 30 percent of Japan's electricity supply comes from nuclear power. What about Indonesia? Is it still intends to build nuclear power plants? (B-prakoso/27210001)
