What influence will nuclear radiation cause to health? The expert gives an idea and protects
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.
It is an acute symptom that disgusting to vomit and generate heat and suffer from diarrhoea
Ministry of Public Health BJ Hospital Yao, head of the department of nuclear medicine, young to say when being interviewed by reporter while being bright: "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, may appear erythema, edema, person who do peel and not getting wet to peel, get up bubble, pain, necrosis, gangrene, the intersection of person who depilate and symptom according to 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.
