What influence - expert will nuclear radiation cause to health to give an idea and protect
Japan's strong shock initiates the nuclear leakage, the nuclear safety problem becomes the focus that people pay close attention to. On the 13th, Chinese nuclear power security expert Yu ZuSheng says, Japanese International Atomic Energy Agency fixes the first nuclear power station rank of explosion accident in Fukushima county for 4 grades, nuclear radiation dosage does not influence the human body actually at present. Then, what influence will nuclear radiation cause to health on earth? Science and Technology Daily reporter has interviewed the nuclear medicine expert. Sick to vomit, generate heat, it suffers from diarrhoea to be acute the intersection of symptom and the intersection of Ministry of Public Health and the intersection of BJ Hospital and young to say when being interviewed by reporter while being bright Yao, head of the department of nuclear medicine: "Radioactive radiation exists in the nature, daily we will touch the radiation from universe under the sunshine when getting sun. So, do not say we can't contact radioactive radiation, the dosage that the more important thing is to accept is within the range of suring. " "The radioactive damage that heavy dose of ionization radiation causes in short time, is called acute radiation sickness. " Yao young to explain, exceed, allow radiation of dosage damage for longer time tomorrow, called chronic radiation sickness. This disease is common to the victim which staff member, the public and nuclear weapons who accepts excessive ray exploded, mainly initiate hematopoietic function obstacle, viscera to bleed, organize necrosis, infecting with and malignant pathological change etc.. Among them, what nuclear radiation leads to the fact shines and damages appearing in the initial stage of typical course of disease of acute radiation sickness mainly outside all over, it is disgusting and vomiting, being tired, generating heat and suffering from diarrhoea to show as. " heal one false " Patient duration size different, symptom is relieved to some extent. There is infecting, bled and intestines and stomach symptom in serious developing into the crisis. Relieved gradually by the above-mentioned symptom after the appropriate treatment. "And it is with shining the difference of the dosage that the part is shone and damaged, tc. and peel, get up may appear erythema, edema, being peeling and wetting symptoms such as bubble, pain, necrosis, gangrene or depilating,etc. and peel, get up m according to the position. Some skin is damaged to usually last from several weeks to several months, the conventional method of the serious one is difficult to cure. However, shine and see more the staff members of nuclear power station outside. " Yao young Ming says in this way. 4000 fine long hair not radiation dosage of the west can cause death in radiating medical science and human radiation to protect, the unit of radiation dosage has many kinds of measurement modes and measurement units. The comparatively intact measurement mode is " The equivalent dosage " ,It is the radiating amount of the biological effect power reflecting various rays or particles cause after being absorbed. Its international standard unit is " The west " ,Define it is per kilogram of tissue that absorbs 1 joule(J), it is not the west. According to the standard that the international radioactive protection committee makes, the always dangerous degree of radiation is not 0.0165 / the west, that is to say, the human body accepts the radiation dosage of the west each time, will increase the carcinogenic probability of 0.0165. "The west is not a very big unit, so does not usually use the west of fine long hair in the west, little. 1 fine long hair the west =1000 little west. " The strongly fragrant grandfather holds explaining, whether nuclear radiation is harmful to human body, how much radiation dosage the key is to see to absorb. Give one extreme figure, people absorb 4000 the intersection of fine long hair and radioactive dosage of west within short time, this is that one causes the dosage of fatal character, people are afraid the life will be dangerous soon. If has absorbed the west of 100 pieces of fine long hair is not following, and add up to the dosage, and another cup of tea. "In daily life, we take 10 hours' flight, will accept not radiation of the west that 30 is little too. " The expert reveals. It is introduced, the nuclear radiation dosage of accumulative total received is not probably about the west of 0.2 writing brushes in normal year of nuclear power station one, that is, claim to be standard 1/10, it is very safe. It is very low that the probability of gene mutation take place in the body cells that the human body grows normally, but if the radiation which the human body accepts exceeds the human body to tolerate the range in certain time, for example under the function of radioactive rays and other radiation, the probability of gene mutation will be heightened, this may cause the original cancer gene to be activated the canceration to take place. Find, in the pathogenic incident of nuclear radiation taking place abroad at present according to information retrieval, patient show as more tired, giddy, insomnia, the intersection of skin and ruddy, ulcer, bleeding, depilating, leukemia, vomit, suffer from diarrhoea,etc.. Serious nuclear radiation will also increase cancer, distortion, hereditary pathological change incidence. Generally speaking, the more radiation energy that the body accepts is, the more serious its radiation sickness and symptom are, carcinogenic and causing the lopsided risk to be the greater. Among them, nuclear radiation person is the aptest cancers such as leukemia, lymphocytic cancer, skin carcinoma, thyroid gland cancer,etc. takes place. Hidden in order to be " be shortened time shone as much as possible by nuclear radiation first by nuclear radiation, keep away from the radioactive source, especially should pay attention to shielding. While passing in and out the nuclear pollution area, should wear the protective clothing, and take a shower in time and remove the nuclear pollution. " The occupational disease precaution clinic of Guangdong Province radiates the medical expert chief physician Yang YuHua to emphasize, it happen nuclear for accident or be be lasted accidentedded, it materials radioactive especially to when not releasing atmosphere, the total shelter principle is " Internal and external and concurrently defend " ,First of all, shorten time shone as much as possible; Far away from the radioactive source as much as possible; Pay attention to shielding, utilize the stereotype, stencil plate or wall to block or reduce and shine the intensity. "When the radioactive material releases on the atmosphere to form the smoke and dust to pass, should enter building in time, close doors and windows and ventilating system, avoid doors and windows,etc. and shield the bad position to conceal. " Secondly, avoid ingestion, reduce, absorb, increase, excrete, prevent polluting districting and staying from. Remove pollution, reduce personnel and pollute the chance in the body. "If the nuclear accident releases the radioactive iodine, should take the stability iodine one as soon as possible under the guidance of doctor. The taking amount adult gives a recommendation for 100 milligrams of iodine, children and baby should reduce as one feels fit, but the iodine is allergic or it is used that the person who has disease history of thyroid gland should be careful. " Meanwhile, must be far away from nuclear radiation. While entering the seriously polluted area the radioactive material of air, should go all out to fight the floods to the facial features. For example, seal and shut up the nose, reduce the sucking of the radioactive material with handkerchief, towel, cloth,etc.. Wear cap, scarf, glasses, raincoat, glove and boot,etc., contribute to reducing the radioactive pollution of body surface. Pay special attention to, don't eat water, food,etc. polluted. If the accident is serious, will need residents to withdraw from the contaminated area, should obey the orders of the related departments, withdraw to the safe place organizedly and in good order. Withdraw and go out of the personnel in the contaminated area, should be taken off and preserved by clothes, shoes, cap,etc. polluted, monitor and deal with. It should remove pollution by the personnel of the radioactive pollution to receive or suspicious, the best method is the shower. Relevant to chain the carcinogenic true case Japan in 1945 that endangers of nuclear radiation: After suffering bombing of two atomic bombs, the lives of Hiroshima, Nagasaki two cities and hundreds and thousands of people receive the serious threat of nuclear radiation. At the the end of 1945, Hiroshima urban size of population fall sharply from 350,000 140,000 about alone, but more and more ground behind that of person surviving Suffer from cancer. Explode and obtain the statistics in the survivor's research to the Japanese atomic bomb according to the scientist: The surviving of canceration take place in those? Is Nai stired the purine as the proud �'s lesson of flashing? 000 the intersection of fine long hair and the intersection of the west and radiation. American report that national academy of sciences deliver 2005 claim in accept radiation dosage up to 100 the intersection of fine long hair and the intersection of the west and philtrum totally, 1% of the people will suffer from entity's cancer (such as hepatocarcinoma) Or leukemia. U.S.A. in 1953: U.S.A. military tried exploding 11 atomic bombs on the level land of Carlos particularly, the last one that is ignited is equivalent (the explosive force of a ton of TNT explosive that per ton of equivalent is equivalent to) of 32000 tons even more "dirty Harry " Atomic bomb. After one year, Hollywood film " conqueror " teleplay group choose until the intersection of nuclear test and place at the the intersection of card and level land 137 the intersection of snow and gorge go on the open air shoot only particularly. The result causes 220 members of teleplay group of this film, nearly half people suck the radioactive dust, have caught fatal cancer. Ukraine in 1986: Cut Pele nuclear power station of the promise and explode, the serious nuclear leakage takes place. It is reported 21 people died on the spot at that time, estimated and influenced by nuclear radiation at first that there are only less than 50 cleaners. In fact cut Pele nuclear power station of the promise and can be rated as to explode " The most serious nuclear accident in history " ,According to the data that Ukrainian Ministry of Public Health announced of 2006, because of this nuclear explosive incident, in the dark people of the whole country 48 million, have 2,500,000 nuclear radiation victims including 473,400 children in all still under the circumstances that medical treatment is supervised. And a regrettable one is, the local child born in Singapore has inborn diseases from that time when the life formed. Among them, deformity, cancer, septicaemia have already become the main killer who kills these innocent children by maltreatment. Cancer leukemia which may be brought out in nuclear radiation: Because nuclear radiation may be high the microwave of frequency, ray cause array changing or sudden change of DNA in the stem cell, especially the increasing severely suddenly of the leucocyte perhaps led to the fact the human immune system was out-of-balance. After the Japanese atomic bomb explodes, it is explaining the impact on human cell proruption of nuclear radiation effectively that the leukemia patient rises sharply. Lymphocytic cancer: The radioactive material is apt to cause the change of the chromosome of lymphocyte, if lymphocytes are in the chronic damage state of the radioactive material for a long time, lymphocytes are difficult to repair by oneself but still survive, has increased the probability of the lymphocyte canceration. Skin carcinoma: To person under the nuclear radiation environment, the skin is that the human body contacts the most extensive place with the external world. In the face of the volatile material or disseminated material of nuclear radiation, the skin will stand in the breach and place oneself in the midst of the dangerous situation. In addition, yellow compares with white race, the white race's skin is easier to damage by the radiation. Thyroid gland cancer: If a large number of radioactive materials are released on the atmosphere, initiate thyroid gland cancer easily, because the radioactive iodine take the share greatly in these radioactive materials, and the human thyroid gland is a main place to gather iodine, eat or inlet the human body into a large amount of radioactive iodine, and accumulate heavy dose of radioactive iodine in the thyroid gland and can damage the thyroid gland or surrounding tissue, certain dosage may bring out thyroid gland cancer.
