Nuclear to protect the main point of knowledge with the radiation accident
1.What is a nuclear accident?
The nuclear accident refers to the state of serious bias operation operating mode taking place in nuclear facilities or nuclear activities. Under this kind of state, if the relevant one has the safety devices specially and can't contribute according to the designing requirement, the release of the radioactive material may reach the unacceptable level.
2.How much kinds of classification does acute radiation sickness have?
Acute radiation sickness is divided into three kinds: Namely bone marrow type, intestines type and brain type radiation sickness. Among them, the bone marrow type radiates old complaints according to being taken the picture the dosage different and dividing into slightly, intermediate, severe and extremely severe bone marrow type radiation sickness. At present, severe the following can treat and cure to live to damage patients to radiate. Extremely severe bone marrow type radiation sickness, enteric radiation sickness and brain type radiation sickness have not been treated and cured into a living experience yet, generally treat the principle in order to lighten patient's agony, lengthen the time of surviving.
3.Is it safe how far to withdraw from?
Under normal conditions, primary task is to limit the emergence exposed in radiation. Reduce the influence that the radioactive smoke cloud subsides through evacuating or concealing influenced population mainly. According to atmospheric release amount and meteorological condition at that time of medium-level radioactive substance ' Such as wind direction and precipitation,etc.) ,And according to central range that explode, country confirm until how large the intersection of radius and planted agent take, conceal the safeguard procedures promptly.
4.How to carry on the self-protection?
It is panic to avoid at first, 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.
5.Which are the risk related to the fact that pregnant? How to reduce these risks?
Because iodine slice blocks the function that the iodine of thyroid gland absorbs, should pay the special concern to take the iodine one to pregnant women. First of all, pregnant woman's thyroid gland high when absorbing the more ordinary adult of the probability of the radioactive iodine. Secondly, the foetus' thyroid gland should be protected, especially the second, third pregnancy period after pregnancy. However, except this, a special medical reason does not indicate that it is pregnant to avoid in cases at present.
6.What connections do dosage and long-term effect have?
Being exposed to ionization radiation may increase the risk of suffering from cancer. Survivor through exploding to the atomic bomb, accept patient, job made a diagnosis to radiate take crowd and the former Soviet Union cut nuclear accident, Pele of promise, take into radiation epidemiology research of crowd, show, when the radiation dosage of whole body is lower than 100 fine long hair to wish, have not found the obvious carcinogenic effect of radiation.
Show to the survivor's investigations of exploding of Japanese atomic bomb, in suffering the next several years for radiation, suffered from the risk of leukemia to increase, the risk of the future trouble cancer increased in 10. In case of nuclear accident, if the radioactive iodine is deposited in the thyroid gland, it will cause some dosage effect of thyroid gland, but not whole body effect. It shows to cut the experience and lessons of Pele's nuclear accident of the promise, the radioactive iodine is the greatest influence factor, accident this lead to the fact age children in 0~18 years old break out the intersection of thyroid gland and the intersection of cancer and over 5000 of case. Cut nuclear accident, Pele of promise, most large to it influences to be the psychological impact. This mainly lacks the risk and links up what the mechanism causes. So under nuclear state of meeting an urgent need, set up one good masses exchange mechanism to be very much important.
