Nuclear physics expert - don't be panic! Japan's nuclear leakage will not influence Guangxi
"According to BBC latest news, Fukushima nuclear power station of Japan has excellent fuel to melt down, nuclear radiation has already been let out, reach Philippine with the monsoon in future 24 hour. Various countries along the line will be influenced by nuclear radiation " In the afternoon of March 15, a rumour information that nuclear radiation may float to Philippine at 4 o'clock on the same day afternoon makes in popular anxiety. Though the Philippine government spikes a rumour, the a little rich official side of many websites gives notice to point out and does not believe rumours quickly. However, nuclear radiation can not be seen, whether may really influence we separated only by a strip of water with Japan? Yesterday, reporters interviewed physical institute's nuclear physics and physics professional Master degree candidate's tutor Professor Wu WeiMing of particle in Guangxi university on this topic, he says clearly: Everybody needn't be panic to Japan's nuclear leakage crisis. The following is the question and answer of reporter and Wu WeiMing - -Reporter: What on earth could you tell me nuclear radiation? Wu WeiMing: Nuclear radiation we speak, mean " cause the intersection of ionization and sub radiation " in the physics generally ,Because the energy of this kind of radiation is quite high. Can cause the ionization of material, thus cause the injury to the human body. However, the influence degree that the nuclear radiation energy produces, relate to dosage of radiation. Reporter: How much dosage nuclear radiation will cause danger to the human body? Wu WeiMing: There are natural radioactive elements on the earth, accept the cosmic ray from the outer space ceaselessly at the same time. This kind is that living environment contain at themselves radiation dosages nuclear 1mSv probably /year (last dog days fine long hair /annual) ,We call it radiation of this bottom, exceeding 10 to 20 times on this dosage may not necessarily exert an influence on the human body, some contact staff member of ray often, or empty to take advantage of personnel throughout the year, the nuclear radiation dosage accepted in one year may often be up to several dozen mSv, but there is influence, vary with each individual. But accept the more dosage of the radioactive element is, big the probability influenced be. Reporter: This time will the nuclear incident of leakage of Japan cause influence on Guangxi? Wu WeiMing: The accident of nuclear power station can cause great influence more on some place, depend on factors such as the quantity, diffusion direction and range of radioactive material that the accident leaks,etc.. Can generally be thought, the influence degree of radiation is inversely proportional to with the square of the distance. Namely the farther from the scene of the accident, the smaller the radiation influence received is. There are reports in Tokyo at present ' About 200 km from Fukushima) Having measured the nuclear radiation of exceeding the dosage of this bottom, but not reached and exceeded the dosage which has influenced the human body yet. Even if the radioactive material leaked can really float to Philippine, according to such a far distance, its influence is very few too. At present in the north of the Japan and in the west and the intersection of Russia and the Far East, South Korea and Taiwan of the south say that has not been influenced, Guangxi where farther with the Japanese distance, the possibility that is influenced will be smaller. Predict this time Japan nuclear progress of radiation accident and I for,there are controllable on it. Because seen from present situation, though the aircrew explodes, this is not a nuclear explosion definitely, have been cut off after shaking automatically as soon as possible because the fission of the reactor reacts, but the cooling of remaining energy left has gone wrong in the reactor, as time goes on, the situation will develop towards direction taking a favorable turn gradually. Everybody needn't be too panic. (yellow pair) According to Xinhua News Agency the relevant news, yesterday, disease in China of Ministry of Public Health accused of centre's releasing nuclearly and protecting the main point of knowledge with the radiation accident, remind citizen should avoid panic, take action according to instruction of government, wait for in the room under a situation storing in in radioactive pollution. It is that China's disease of the main safeguard procedures accuses of centre's saying to conceal, being exposed to ionization radiation may increase the risk of suffering from cancer. Cigarette how far cloud can float very difficult to predict it depends on wind speed and other meteorological conditions behind the nuclear accident. In the early and middle period of the accident, it is one of the main safeguard procedures to conceal, most buildings can make the personnel in the building suck the dosage to nearly reduce by half, concealing time generally thinks that should exceed 2 days. The shelter of the personal body surface can use various daily clothes, to already or suspected that has been decontaminated by the personnel of the radioactive pollution of body surfacing, the method is simple, can use the water shower, and will be taken off and preserved by clothes, shoes, cap,etc. polluted, find or deal with if having time until the afterwards. Should not take to a citizen of iodine without authorization to should avoid panically, listen to radio or watch the TV in time, according to the instruction action of the government. Under having situation existing in radioactive pollution, stay in the room. The administration of the iodine slice should be in accordance with the instructions of the government, only the government could determine whether to need to take the iodine one after assessing the accident state. Can't assume subjectively or take without authorization because of being frightened only according to individual. The panic state of removing the psychology " after the nuclear accident happens, even not received radiation, also will feel afraid, what reason is this? " China's disease is accused of to explain in the centre, no matter receive real irradiation, will all have spiritual anxiety. This kind of situation is due to people's dangerous self- feeling to health, its part depends on whether people believe the responsible institution has the ability and are worth relying on, whether have already adopted the fast but effective action to control radiation dosage. Medical workers should dredge the essential psychology to people, remove the panic state of the psychology.
