Nuclear accident The long-term effect is incomparable
After Japan's heavy earthquake, already the favorable turn appears in the short-term situation out of control of nuclear explosion, but it is still hard to assess to influence midium or long term of the mankind, marine organism, atmospheric environment. Please see experts and understand and cut the health story after Pele's nuclear accident of the promise, hope to offer reference to this disaster. On April 26, 1986, the ones that lay within the boundaries of Ukraine of the former Soviet Union cut Pele's nuclear reactor No. 4 of the nuclear power station of promise and exploded, aircrew's damage, more than 8 tons of radiation materials are revealed, the pollution of radiation produced by this is that the atomic bomb of Hiroshima of Japan exploded several hundred times polluted in radiation emerging. This is the most serious nuclear accident since the dawn of human civilization, it is that only one is fixed for 7 grades of nuclear accidents up until now too. The radiation dust let out spreads western region, eastern Europe area, North Europe Scandinavia to the Soviet Union with the atmosphere, among them it is the most serious that Ukraine, Belarus, Russia receive pollution. Because of the reason of the wind direction, nearly 60% radioactive material drops on land in Belarus, a large number of nearby residents are forced to flee from. Remained as before after effect the 1/4th century at a specified future date After the accident happens, several hundred people are sent to the hospital treatment, several dozen people among them died in excessive radiation, as many as ten thousand people are fatal or seriously ill because of radioactive material radiation. The person of the death is fire fighter and medical personnel mostly, they did not know at that time this accident contains the danger of fatal radiation. Accident this leak because of serious core, cause, appear the acute determinacy (at random) by the intersection of contaminated area and person Damage the effect and chronic and damage the effect at random. Acute to damage the effect and is caused by the shining outside and shining inside of radioactive material. It mainly causes hematopoiesis, immunity, gastrointestinal tract to damage to shine outside, it causes the damage of thyroid gland,etc. to shine inside. Receive it on the basis of the ones that absorbed dosage according to personnel, has presented the manifestation of the acute radiation sickness of different degrees, have caused peripheral blood leucocyte at various degrees, erythrocyte, blood platelet and hemoglobin to reduce, behave after presenting infection, anaemia, bleeding and ulcer of different degrees,etc.; The immunological function is low, easy to be tired; Clinical manifestation such as losing the appetite, nausea, vomiting, suffering from diarrhoea. After this accident of Japan, " the person dies " to stand fast at 50 in the nuclear power station May be influenced by this effect, it is reported that already 6 people have received high density radiation among them. After cutting Pele's nuclear accident of the promise, except producing obvious acute hematopoiesis, immunity and gastrointestinal tract and radiating and damaging symptom, have also caused it even chronic damage effects taken place all the life of several months, several years after shining, namely long-term effect. Though this accident has been already in the past 25 years, it still exists to healthy danger. The main long-term effect is as follows, the peripheral blood cell reduces, reduce for being apparent with the leucocyte particularly; The leucocyte can present the ripe obstacle to even regenerate low in the bone marrow, bone marrow and peripheral blood cell chromosome distortion rate increase; Can initiate leukemia and other types malignant tumour, such as thyroid gland cancer, lung cancer, breast cancer, skin carcinoma, malignant lymphoma,etc.; The sex function is low, even infertile, sterility; Foetus mortality increase and organ form obstacle, stillborn fetus or odd-shaped development appears; Neonatal mortality increases, present little head deformity, intelligence hypoplasia, grow teratogenesis' probability of slow sum increases etc.; Children's thyroid gland cancer incidence increases etc.. Protect, try hard, avoid, take in, infected with food, the shelter of the nuclear leakage takes place to nuclear accident middle period, the safeguard procedures taken in early days are mainly as follows, 1. Pay attention to concealing. Hide in the room before the radioactive pollutant is reached, close the doors and windows and avoid the doors and windows, can shield the window with the brick, sun-dried mud brick, sand bag if necessary. 2.Withdraw fast as much as possible. Crowd that withdraw should take into high dosage, might take place determinacy damage relatively little crowd of effect, should take the obscure method to bigger crowd. 3.The essential medicine is protected. Can take KI slice under the guidance of professional doctor. To that the shelter of the nuclear leakage happens in the nuclear accident, the safeguard procedures taken in middle period are mainly as follows, 1. Move the crowd out from the contaminated area. 2.The controller enters the contaminated area. Except carrying out the personnel of the task of rescuing, monitoring etc., other personnel are forbidden to enter people's contaminated area without exception. 3.Control and take in food and drinking water infected withed. This is food preventing personnel's ingestion and is infected with and main measure that the drinking water shines while causing. After leakage took place in the radioactive material, the environment will be infected with, thus make vegetables, fruit, source of water,etc. receive radioactive contamination, should control food and water. If must eat and is infected with the food, can use water washing or remove the top layer infected withed, method to prune peel and remove the radioactive pollutant in the vegetables and surface of fruit. It is reported the locality has already presented the vegetables, radiation amount of running water and exceeded standard at present, though may be still not enough to cause the health to damage, must cause the concern. 4.The building, road and workplace receive the pollution of the radioactive material to wash and disappear. Can carry on cleaning up, water washing, covering or shaving the top layer,etc..
