In 1996, song Xuewen, a 20-year-old boy from Jilin Province, accidentally picked up a metal chain with nuclear radiation. The intense radiation made him lose his legs and left forearm. Over the years, song Xuewen has been living very hard, getting married and having children, writing novels, making movies and running kindergartens. He said: 'I will try my best to make money for the rest of my life, hoping to leave a guarantee for the future of my wife and children. 'unfortunately, the radiation damage has been lurking in his body. On April 23, song Xuewen died.
Harm of nuclear radiation to human body
The general impact of nuclear leakage on personnel is reflected in nuclear radiation, also known as radioactive substances. Radioactive substances can be inhaled through breathing, absorbed into the body through skin wounds and digestive tract, causing internal radiation. Y radiation can penetrate a certain distance and be absorbed by the body, causing external radiation injury to personnel. The symptoms of radiation sickness caused by internal and external irradiation include fatigue, dizziness, insomnia, skin redness, ulcer, bleeding, alopecia, leukemia, vomiting, diarrhea, etc. Sometimes it will increase the incidence of cancer, aberrations, genetic diseases, affecting the health of generations. Generally speaking, the more radiation energy the body receives, the more serious the symptoms of radiation sickness, and the greater the risk of cancer and deformity.
The slight damage of nuclear radiation to human may result in mild acute radiation sickness, such as fatigue, discomfort and loss of appetite.
The moderate damage of nuclear radiation to human can cause moderate acute radiation sickness, such as dizziness, fatigue, nausea, vomiting and decrease of white blood cell count.
Although treated, 50% of the patients may die within 30 days, and the other 50% can recover. The symptoms were vomiting for many times, diarrhea and obvious decrease of white blood cell count.
The harm of nuclear radiation to human beings is very serious, which causes very serious radiation diseases, and the mortality is very high. Many times vomiting, diarrhea, shock, white blood cell count decreased sharply. The radiation of nuclear accident and atomic bomb explosion will cause immediate death or severe injury. It can also cause cancer, infertility, freaks and so on.
The following are the consequences of the amount of radiation (in millirem) suffered:
450000-800000: they will be in the state of dying within 30 days;
200000-450000: hair loss, serious blood disease, some people died within 2-6 weeks;
60000-100000: various radiation diseases occurred;
10000: the probability of cancer was 1 / 130;
5000: the amount of nuclear radiation suffered by the work every year;
700: the amount of nuclear radiation in brain scanning;
60: radiation in human body;
10: The amount of radiation suffered by flying;
8: The annual amount of radiation generated by building materials;
1: The amount of radiation from an X-ray of the leg or arm.
(Note: the unit used here is rem, and the current unit is SV 1SV = 100rem)
Injury of embryo and fetus
Embryo and fetus are more sensitive to radiation. Exposure to radiation before embryo implantation can increase the rate of stillbirth; exposure during organogenesis can increase the rate of fetal malformation and neonatal mortality. According to epidemiological investigation, the incidence of leukemia and some cancers in the irradiated children during the fetal period is higher than that in the control group.
Long term effects of nuclear radiation on human beings
In the medium or high dose range, the carcinogenesis of nuclear radiation has been confirmed by animal experiments and epidemiological investigation. The incidence of lung cancer, thyroid cancer, breast cancer and bone cancer increased with the increase of radiation dose.
Sequelae of nuclear radiation pollution
Six months after exposure to radiation, there will be changes in the body, including lens opacity, cataract, permanent infertility caused by male testicles and female ovaries, bone marrow damage, hematopoietic dysfunction, and various cancers.
On the other hand, there will be genetic effects, which will lead to genetic or chromosomal variation of germ cells, leading to teratogenesis and other problems.
