Whether seeing nuclear radiation blue light is harmful
Whether seeing nuclear radiation blue light is harmful, nuclear radiation is the atomic nucleus from a structure or an energy state into another structure or another energy state released in the process of the flow of microscopic particles, then see whether nuclear radiation blue light is harmful, let's take a look at it.
Whether seeing nuclear radiation blue light is harmful1Nuclear radiation blue light is extremely harmful to the body!
What is the harm of nuclear radiation?
Early nuclear radiation in the first ten seconds of nuclear explosion radiation out of the human eye can not see the gamma rays and neutron flow. It is a unique destructive factor of nuclear explosions. Early nuclear radiation close to the speed of light in a straight line. When the flash of light is detected, the personnel have long been subjected to the action of the rays.
Early nuclear radiation can penetrate the human body and objects like X-rays, and can penetrate thousands of meters of air. When the ray irradiation to the human body, killing cells to a certain extent, the personnel will get radiation sickness; irradiation to the soil, salt, alkali, food and some metal appliances, but also to make these original non-radioactive material to produce a sense of radioactivity, but also on the personnel to cause harm. It can also darken optical glass, film exposure, chemical failure, and can affect the performance of electronic instruments.
In radiology and human radiation protection, there are various modes of measurement and units of measurement of radiation dose. A more complete measurement model is the "equivalent dose", which is the amount of radiation that reflects the strength of the biological effects caused by the absorption of various rays or particles. Its international standard unit is the "Sievert", defined as 1 Joule per kilogram of human tissue absorbed, for 1 Sievert.
The human body suffers from excessive radiation, which may lead to fatigue, dizziness, insomnia, skin redness, ulcers, bleeding, hair loss, leukemia, vomiting, diarrhea, etc., and sometimes increase the incidence of cancer, malformations, hereditary lesions, and the impact on the health of several generations. In general, the more radiation energy the body receives, the more serious its radiation sickness symptoms, the greater the risk of cancer and teratogenicity.
According to the standards set by the International Commission on Radiological Protection, the total risk of radiation is 0.0165/siever, which means that for every 1-sievert dose of radiation received by the human body, the chances of cancer will increase by 0.0165. Sieverts is a very large unit, so millisieverts and microsieverts are usually used. 1 millisievert = 1000 microsieverts. According to Yu Zusheng, a nuclear power safety expert in China, according to China's standards, each person should be exposed to less than 2.7 millisieverts of radiation per year. In fact, the human body is not affected if it is exposed to less than 100 millisieverts of radiation for a short period of time. A radiation dose of more than 4000 millisieverts can be fatal.
How does nuclear radiation affect human health?
When radioactive material decays, it releases ionizing radiation, which can cause serious damage to the body's internal chemical environment. It breaks the chemical bonds between various atoms and molecules in various tissues of the body, and the body reacts automatically to try to repair the damage. But sometimes the damage will be so extensive and severe that repair is almost impossible, and there is also the possibility of errors in the automatic repair process. The most sensitive parts of the body to radiation damage are the tissue cells in the gastrointestinal tract, and the blood-forming tissue cells in the bone marrow. The amount of radiation damage depends on how long you are exposed to the radiation and how much radiation you receive.
Do iodine pills work to prevent nuclear radiation?
Some commonly used radiation protection measures, such as drinking green tea, eating fungus, wearing a mask, wearing a radiation suit for pregnant women, do not work at all. The best way to protect yourself from radiation contamination is to close the doors and windows of your home, and to wash your hands and take a shower. Iodized salt contains iodine and its trace, eat iodine medicine must also be subjected to nuclear radioactive contamination, once a day, each time a potassium iodide, to buy their own ahead of time to eat, which in turn, the body will cause harm to the drug.
See nuclear radiation blue light is harmful 2What is nuclear radiation?
Nuclear radiation is a stream of microscopic particles released during the transformation of the nucleus of an atom from one structure or energy state to another. Nuclear radiation can cause ionization or excitation of matter, so it is called ionizing radiation. Ionizing radiation is divided into direct ionizing radiation and indirect ionizing radiation. Direct ionizing radiation includes alpha, beta, protons and other charged particles. Indirect ionizing radiation includes photons (γ-rays and X-rays), neutrons and other uncharged particles.
Nuclear radiation refers to radiation from the nucleus of an atom. There are three main types of nuclear radiation that affect humans, namely alpha, beta, and gamma rays. alpha rays are a stream of particles made up of the nucleus of the helium atom. It has a large mass and much charge, but the ability to penetrate the material is weak and the range is short, as long as an ordinary piece of paper can be blocked. However, if it enters the human body, it can cause harmful internal damage, so it is important to protect against alpha rays in particular to prevent them from entering the human body.
β-rays are composed of high-speed electrons, and α-rays have a greater penetrability compared to the skin's stratum corneum, which can penetrate the skin and cause damage to living tissue. However, it is easily shielded by materials such as plexiglass, plastic or aluminum plates, and its intrinsic harm is less than that of α-rays. γ-rays are similar to x-rays, and are also composed of invisible photons.
It has the strongest penetrating power, can penetrate a meter thick cement wall, an energy of 1MeV of γ-rays is enough to penetrate the human body, so the protection of γ-rays in the protection of external irradiation is the most important, due to the γ-rays are not charged photons, it can not directly cause ionization, so it is the harm to human body irradiation than the α, β-rays are small.
What are the hazards of electromagnetic radiation on the human body?
Electromagnetic radiation has been listed by the WHO as the fourth largest source of pollution after water, air and noise. Prolonged exposure to excessive electromagnetic radiation can harm the reproductive, neurological, and immune functions of the human body, and can lead to skin diseases, diabetes, cardiovascular diseases, and cancers.
Please note that the above sentence is saying that long-term excessive electromagnetic radiation will definitely cause damage to the human body. Our 'requirement for magnetic field strength is not to exceed 100 microtesla. For low intensity electromagnetic radiation, will long-term accumulation have an effect on the human body, although there are many relevant studies, but so far, there is no evidence that low intensity exposure to geomagnetic radiation will have an effect on human health.
How strong is the electromagnetic radiation from the household appliances we use every day?
Generally speaking, the strength of the magnetic field varies greatly from brand to brand. A strong magnetic field can be generated around a home appliance, but another home appliance may have little to no magnetic field around it. In addition, the strength of the magnetic field can change with distance. According to the German Federal Office for Radiation Safety radiation testing of some household appliances in 1999 showed that: most household appliances at 30 centimeters produce a magnetic field strength of completely in the public safety standards limit of 100T below the normal use of the distance can be referred to in the table below.
Take Zongqing Technology's Intelligent Habitat System as an example. Zongqing Smart Habitat system is an air purifier that can release "forest-level" high activity, high migration distance negative oxygen ions, which can effectively remove haze, sterilize and disinfect, decompose toxic and hazardous substances, and so on. In the CCTV near science "indoor haze 3.0" report, Beijing professional testing organizations, in an elementary school in Beijing, the installation of intelligent Habitat for Humanity system classroom testing, the magnetic field value of about 30 Latt, with the national standard value of 100T difference of about 1000 times.
Many countries' official organizations have conducted various measurements of electromagnetic radiation in the living environment, and have not found that electrical appliances and other electromagnetic radiation have any impact on human health, even the closest cell phone to our head, although its radio frequency electromagnetic field strength is much higher compared to general electrical appliances, but it is not found to have an impact on health.
What is the harm of nuclear radiation, and how scary is it?
The nuclear accident at Fukushima a few years ago had the world on edge. At the same time, the nuclear tests conducted every now and then by a country on the peninsula have made people feel that the nuclear threat is all around them.
For most people who have not experienced the threat of the Cold War, nuclear radiation is a very fuzzy concept, and the following two real cases can tell us how terrible the destruction of nuclear radiation for people!
Incident 1
On January 5, 1996, Pingping (a pseudonym), a 20-year-old worker at a construction company in Jilin Province, picked up a metal chain on his way to work, mistaking it for a BB chain, and put it in his personal pocket. Two hours later, Pingping appeared dizziness and nausea, the body red and swollen, covered with blisters ......
Afterwards identified, Pingping picked up the metal chain for the unit r ray detector radioactive source radioactive - metal iridium-192. diagnosed, Pingping whole body by the The amount of radiation is about 2.4gy, more than 7,477 times the normal limit. Jilin Provincial High Court in 2000, the final judgment, due to the overdose of misdiagnosis Ping Ping to its lifelong disability. The construction company in addition to the salvage treatment costs have been paid, another compensation Pingping more than 480,000 yuan. This case is the first case of nuclear radiation in China, Pingping also became the country's most severely affected by nuclear radiation.
Although some compensation, but in Pingping's view, the world, in addition to no regrets, there is no medicine for nuclear radiation. He profoundly realized that life after being exposed to nuclear radiation, "suffered from endless physical and mental torture."
Since 1996, Pingping has undergone seven surgeries, "basically where the rot where to cut", limbs in addition to the right arm have been amputated. Not only that, he also developed radioactive cataracts, memory impairment, right hand neuroma, cirrhosis of the liver, gastrointestinal bleeding and diabetes a series of diseases.
Since 1996, Ping has been struggling to survive for 22 years, and the one mentioned below almost watched his body decay until he died, and it may be that for him, the death that eventually comes may instead be a relief.
Incident 2
On September 30, 1999, a nuclear fuel treatment plant in Kaito Village, Ibaraki Prefecture, Japan, was involved in a critical accident (1) because of a worker's non-compliance with the operation, in which a worker half a meter away from the source of the radiation was exposed to a dose of radiation of about 23Gy. This amount of radiation was nearly 10 times the amount of radiation received by the aforementioned Heihira.
The worker was no different from a normal person when he was first brought to the hospital; he had only darkened his skin a bit and his right hand appeared red and swollen. There were no signs of burns on his body, and he was very conscious, not like he had been exposed to severe radiation.
However, the results of the examination showed that the 23 pairs of chromosomes in his body were originally arranged in an orderly manner, some of them were disconnected from a few cuts, and some of them were glued together, turning into a chaotic mess, which is far more serious than ordinary single-pair chromosome abnormality diseases, such as Down's Syndrome.
The chromosomes, which serve the function of transmitting genetic information, are destroyed, and the cells in the body of the worker completely lose their ability to proliferate. The cells in his body were dying, but no new cells were being produced. Within a week of being admitted to the hospital, his white blood cells had dropped to less than 1/10 of a normal person's. With the loss of the immune function of white blood cells, even trivial bacterial infections can kill Ouchiju. Every time he tore off the medical tape on his body surface, a piece of his skin or mucous membrane was torn right off and could not be regenerated, leaving irreparable traces and pain all over his body, after which he could only keep putting on gauze to block the seepage of bodily fluids as much as possible.
Twenty-seven days after being admitted to the hospital, his intestinal mucosa began to peel off in patches, and without the protection of the mucosa, digestive juices began to digest his own tissues, resulting in massive diarrhea. Because of the oozing of skin fluids and diarrhea, he was losing 10 liters of water per day. The constant rehydration in turn aggravated the heart to such an extent that the pulse rate reached more than 120 beats per minute, the equivalent of an athlete lying in a hospital bed. On the 59th day of admission, he suffered a cardiac arrest, and although aggressive resuscitation restored his heartbeat, the resultant brain damage was so severe that the worker lost all consciousness.
There was nothing the doctors could do about it but keep replenishing the blood cells through blood transfusions. After 83 days of suffering, his life came to an abrupt end just before the millennium.
In this incident, 213 people were exposed to varying degrees of radiation, and one of the co-workers of the said worker died more than 200 days after he was admitted to the hospital. After the incident, the company involved was fined 1 million yen based on the results of the investigation. The people in charge were also criminally sentenced.
Summary
Nuclear energy has always been a good thing. The power of nuclear energy has always brought convenient benefits to both civilian and military applications. But it is also ruthless, and if humans can't control it properly, it will hurt them. People like Song Xuewen and Hisashi Ouchi should not be relegated to painful memories, but should be made to rethink how to avoid harm while maintaining development.
