After the 311 earthquake in Japan, all parts of the world have once again become aware of nuclear energy.Is it not clear about the threat of nuclear energy?Women fans tell you.

Otherwise, why are they stockpiling iodine tablets?

Radiation from the minerals, atomic bombs, and nuclear reactor fires a major effect on human body: DNA becomes decay and disintegrates, not to the extent that it is destructive enough to cause it to mutate and eventually lead to cancer.

After Japan's earthquake and tsunami last week, four nuclear reactors at Fukushima's first nuclear power plant have been hit hard and have led to a radiation leak.Workers who tried to stop the nuclear reactor from getting worse were exposed to danger when the government called for a 20-kilometer-long retreat from the area.

Unlike the radiation of ordinary light bulbs or microwave, the power of nuclear radiation is enough to kick out electrons in atoms and generate ionization.Free radiation can cause damage directly to DNA molecules, and can interfere with the links between molecules, including DNA, by destroying links between atoms, or by ionizing water molecules to form free radicals, and highly reactive properties.(Extended Read: Age: Long term chronic inflammation is fatal )

What's happening now is that radioactive elements are experiencing decay and radiated high-energy particles, " explained Peter Dedon, a professor of radiation protection at the Massachusetts Institute of Technology.And if you're standing in these high-energy particles, they're going to react with the cells in your body.Literally, you get a particle, an energy bag, and it passes through your cells and tissues."

If the radiation changes the DNA molecule to a certain extent, the cell will not be able to reproduce and die on its own, and it will quickly generate radiation sickness such as nausea, tumor, hair loss, etc.While less severe cells can survive and replicate, structural changes produced in their DNA interfere with the normal course of operation, such as a mechanism to control how and when cells divide.The cells that don't control their own fragmentation can grow out of control and become cancer.

Dedon said, with the intake of particles, some may leave the body before they cause damage, but others remain in the body.A radioactive iodine-131 would have a significant risk because it would be absorbed quickly and retained by the thyroid.This is why people who may be exposed to radiation in the air must first take iodine pills: non-radioactive iodine is first absorbed by the thyroid, thus avoiding the absorption of radioactive iodine if it enters the human body.

Calculating exposure to radiation exposure is called sievert, which takes into account the type and quantity of radiation, and which body parts are exposed, allowing us to compare different types of radiation exposure in the same scale.

In one year, one person may be able to absorb a total of 2 or 3 millisievere radiation from the surrounding radioactive environment, aircraft navigation, and medical treatment.In the United States, a one-year limitation exposure of a nuclear power plant worker is 0.05 Sever.At or below this level, the repair of DNA's enzymes is still sufficient to reduce the risk of cancer.If this level is exceeded, the repair system in the human body cannot keep up with the damage.The World Nuclear Association points out that 100 millisievers a year is the threshold that determines whether the risk of cancer begins to increase.

According to the report, the number of constant radiation levels in Fukushima has increased by 400 millisieveran hour.Dedon explained that this level of radiation would be sufficient to reach the United States' standard for seven minutes.More than an hour will be fatal.

Dedon emphasized that radiation would dissipate as light, and that even if the radiation levels within the plant were high, there would not be any radiation effects in a few miles.For residents living in the region, the greatest danger is that radioactive particles released into the air will accumulate in the body, gradually harm the body tissues, and cause cancer.(Extended reading: courage to face cancer!)"I am not a born optimistic"

Dedon said it would be enough for you to absorb the radiation level of one Siphs in one day." The radiation levels from 1 to 3 Sever will begin to harm your bone marrow and organs, and it is then determined that you are sick.The radiation levels from 3 to 6 sieverdo will also cause you to start bleeding and cause more infections, " he said, adding that the death rate would rise to 90 percent in the six to 10 siever-cifer levels.If we exceed 10 sivers, then there is nothing to do."
