Military academy of medical sciences radiate with the intersection of radiation and medical auspicious March 11, 2011 such as cloud Peng, researcher of research institute, 9.0 magnitude of heavy earthquake take place in Japan, shock the whole world. Earthquake this let question that people pay close attention to the fact and afraid tsunami that initiate by earthquake most and nuclear power station leak the grade born the disaster. Fukushima, after reactor explode first 1 such as nuclear power station, size 3 reactor, size 2 reactor and reactors go wrong in succession the 4th, have already now found that there is nuclear leakage of a certain degree, and already confirmed having many people to receive the radioactive material to pollute. The nuclear radiation that is released on the the afternoon of March 15 monitors saying, the nuclear material has already floated to Tokyo, the radioactive rays amount of Tokyo area has already exceeded usual 20 times. Foetus and children are most afraid of radiation at present, 131 iodine of radioactive element produced while already measuring to nuclear fission near the nuclear power station and 137 cesium. 131 iodine will cause the thyroid gland to damage mainly, 137 cesium will cause the hematopoietic system to damage mainly. Closely related to intensity, distance and wind direction,etc. that the radioactive pollutant leaks that perhaps the health brought is endangered that the nuclear power station is let out. The micro- radioactive material will not cause obvious influence on the health, but if heavier dose of radioactive pollutant is leaked, will cause damaging to the organism. The human body most sensitive to the radioactive rays histoorgans such as hematopoietic system, immune system, genitals and gastrointestinal tract,etc. splits the cells vigorous in hyperplasia. If ray radiation reaches certain dosage, can cause the peripheral blood cell to drop, will initiate symptoms such as infection, anaemia and bleeding,etc.; Will cause the organism immunological function to be low, apt to be tired, etc; Will damage the gastrointestinal tract, cause losing the appetite, disgusting, vomiting, diarrhoea,etc.; The leading to the fact function can also be low, even infertile, sterility,etc.. Need to emphasize, under the same radiation dosage, the influence that the foetus receives is the biggest, it will be greater than the adult too that children are influenced. This is a highly sensitive to ray because inmature and active in hyperplasia tissue cell. After the foetus of growth is shone, may cause foetus death. If in addition, are influenced by radiation in different time for development of embryo, its consequence is different, burn embryonated egg of bed might split up no longer, but foetus in organ form issue, can cause stillborn fetus or odd-shaped development. Radiation will also cause the increase of neonatal mortality. Nuclear radiation will bring the ray of certain dosage of the long-term effect besides producing acutely and radiating and damaging the effect, may also cause long-term effects even hereditary effects. The long-term effect refers to even chronic damage effects taken place all the life of several months, several years after shining, including blood and hematopoietic system changing, cataract, malignant tumour, fertility dropping, embryo's deformity, teenagers' development obstacle, life-span shortening and hereditary effect,etc.. Long-term effect can take place recovery person already after it is damaged that acute, can also happen for a long time low dose of person who shine on one's body, it can cause to shine outside and shine inside. The ray will damage blood and hematopoietic system, lead to the fact peripheral blood leucocyte, erythrocyte, blood platelet and hemoglobin are reduced, it is most apparent to reduce with the leucocyte particularly. The ray will initiate leukemia and other type tumours, such as lung cancer, breast cancer, thyroid gland cancer, skin carcinoma,etc.. Generally happen after shone for 3~8 years, in order to see more by acute, chronic grains of cellulous more leukemia, secondly it is acute lymphocytic cellulous leukemia. The ray can accelerate people's aging. Organism collagenous thread wither and contractile force lose after people shine, will appear change that similar to the elderly, if the crystal is muddy, the iris will wither, the hair decolorizes, changes dust or turns white, the skin elasticity is weakened. It may make people's life-span shorten to shine, and the life-span shortens and presents the linear relation with the dosage. Japan nuclear leakage influence the Japan loud earthquake to initiate the nuclear power station to leak yet our country, not finding radioactivity unusual in our country yet at present, but the incident of leakage of nuclear power station caused by heavy earthquake has not been over yet, still need to cause and pay close attention to, and monitor and radiate the dosage and take the essential safeguard procedures closely. There are the following respects to the safeguard procedures main in radiation: It is far away from radioactive pollutant that fast as much as possible; Ask professional personnel to measure dosage of radioactive rays that may be accepted; Carry on essential health examination, it is checked that the for instance peripheral blood is alike, is it easy and tired and having symptom of vomiting and suffering from diarrhoea etc. to have to pay attention to; Once find that there is the unusually radioactive material or above-mentioned uncomfortable symptom, should go to the professional medical organization to further check and treat as soon as possible. Extend and read Fukushima nuclear power station lies in the nuclear power station of Fukushima county of Japan there is Fukushima first nuclear power station and Fukushima second nuclear power station, they are all run by Tokyo Utilities Electric Co.. The reactors of two nuclear power stations regard ordinary water as the boiling water reactor of coolant and neutron moderator. Compared with pressurized water reactor, this kind of reactor structure is simpler, security is higher. Before this heavy earthquake, there are 7 reactors in operating state in all in Fukushima first and the second nuclear power station, the earthquake is all closed automatically after taking place. After the nuclear incident hierarchical Japan's earthquake, the leakage of radioactive material takes place in Fukushima first nuclear power station. Japanese Government fixes this nuclear accident for 4 grades tentatively. According to International Atomic Energy Agency" The international nuclear incident hierarchical table " Regulation,last 7 grades nuclear safety incident altogether, among them 1 grade to 3 grade is for incident; 4 grade to 7 grade is the accident. In history, the former Soviet Union of 1986 cut Pele's nuclear accident of the promise was defined as most serious 7 grades. (Xinhua)
