The Japanese nuclear power station is not a nuclear explosion A large number of radioactive iodine can bring out cancer
Cause Fukushima nuclear power station of Japan to explode to 311 heavy earthquakes of Japan, cause some radioactive materials to leak, the second gentle researcher of safe king of research institute of the radiation of China National Atomic Energy Science Research Inst has explained the angle that the human body injured in detail from principle and radiation of exploding.
It is not a nuclear explosion that first, hydrogen explode
This nuclear accident is mainly because the cooling water supply of the reactor is cut off, result in piling the core to melt partly, the pressure is too high, the water temperature is too high outside the nuclear fuel container, decompose, the hydrogen and oxygen emerge, the hydrogen happens to explode, cause some radioactive materials to leak. This kind of explosion is caused by chemical reaction, it is not a nuclear explosion.
Second, radioactive material is the radioactive iodine
The serious accident happens in the reactor, a large number of radioactive materials are released on the atmosphere, among them the radioactive iodine takes the share greatly. The radioactive iodine mainly shines to the crowd from 4 kinds of routes. The ones that polluted the air sucked, polluted the shining outside of the ingestion of the food and water, radioactive iodine absorbed and deposited by the skin. Generally speaking, food, water and milk of the air and ingestion pollution which suck pollution are the most important route of shining.
Third, heavy dose of radioactive iodine may cause thyroid gland cancer
The human thyroid gland is a main place to gather iodine, the ability that the thyroid gland gathers the iodine is very strong, or suck the route to enter internal radioactive iodine, accumulate in the thyroid gland by ingestion, heavy dose of ( Above 2Sv) Can damage the thyroid gland or surrounding tissue, certain dosage may bring out thyroid gland cancer. Could observe the increase of cancer in only dosage above 100mSv of epidemiology, kindling canceration that it is the easier that age is the smaller. Take the iodine of stability immediately after or take in before taking in the radioactive iodine ' Iodine slice) ,Can prevent or reduce the absorption in the thyroid gland of radioactive iodine, play a role in protecting. (Sv represents that studies the expert who the radiation living beings protect
Can't observe any change in fourth, low dose of radiation
In order to prevent unnecessary radiation, stipulate professional personnel's annual dosage limit is 20mSv, the public is 1mSv. The natural radiation dosage that we receive is 2-4mSv in daily life, go to the hospital to make once CT inspection, radiation that receive about shining under the 11mSv.100mSv, observe any change on being clinical.
