The hazards of radiation in the central control room to humans
The hazards of radiation in the central control room to humans. Radiation refers to high-energy rays such as solar radiation, gamma rays, and nuclear radiation, and the radiation in the central control room It is relatively large. Let me and everyone take a look at the relevant information on the harm of radiation in the central control room to people. Let's take a look. Harm of Radiation in the Central Control Room to Humans 1
Excessive exposure to radiation in the control room may cause vision loss, even blurry eyesight, and can easily induce diseases such as cancer. , being in this environment for a long time may also cause endocrine disorders in the human body. In addition, if a pregnant woman is exposed to radiation for a long time, it is likely to cause malformations in the fetus, and even cause damage to the health of the pregnant woman. It is necessary to promptly Stay away from ionizing radiation and do more activities outdoors.
If you are exposed to radiation for a long time, it may damage human health to a certain extent, causing the body's immune function to be suppressed, which can easily induce blood diseases or cancer, and staring at the TV or computer in the monitoring room for a long time Watching screens can cause eye fatigue and even lead to symptoms such as vision loss.
It is recommended that if you need to work near a radiation source for a long time, you can choose to wear radiation-proof clothing, rest your eyes properly, and do some eye exercises to relieve eye fatigue. Pregnant women and other special groups should avoid exposure to radiation sources.
Radiation pollution will affect the human body's circulatory system, immunity, reproduction and metabolic functions. In severe cases, it can induce cancer and accelerate the proliferation of cancer cells in the human body. Effects on people's cardiovascular system include palpitations, insomnia, menstrual disorders, bradycardia, reduced stroke volume, sinus arrhythmia, leukopenia, decreased immune function, etc. in some women. Excessive electromagnetic radiation pollution can also affect the health of people. effects on the visual system. The main symptoms include decreased vision and cataracts.

Radiation is very harmful to the human body. As the most common reason for ordinary people to be exposed to radiation, they are usually exposed to radiation through medical examination and treatment, such as chest X-rays and Chest X-ray, CT, radiotherapy, etc. Radiation can affect the human body's circulatory system, immunity, reproductive and metabolic functions, and in severe cases can induce cancer. Secondly, radiation can also affect the human cardiovascular system, causing palpitations, insomnia, and some women. Menstrual disorders, bradycardia, decreased cardiac output, decreased white blood cells, decreased immune function, etc.; it can also affect the human visual system, such as decreased vision, cataracts, etc.
What are the hazards of induction cooker radiation to the human body
1. Electromagnetic radiation is one of the main causes of cardiovascular disease, diabetes, and cancer mutations;
2. Electromagnetic radiation can cause direct damage to the human reproductive system, nervous system and immune system;
3. Electromagnetic radiation is one of the causative factors causing miscarriage, infertility, teratology and other diseases in pregnant women;
4. Excessive electromagnetic radiation directly affects children's body tissue and bone development, leading to a decrease in vision and liver hematopoietic function. In severe cases, it can lead to retinal detachment;
5. Electromagnetic radiation can reduce male sexual function. , Female endocrine disorders.
In fact, the harm of induction cookers mainly comes from electromagnetic radiation. Although the radiation frequency of induction cookers is only equivalent to one-sixtieth of the frequency of mobile phone signals, the radiation power is much greater than that of mobile phone signals. The radiation power mainly depends on the electromagnetic wave leakage value of the induction cooker. The greater the leakage, the greater the harm to the user! Long-term or long-term use will have a greater negative impact on human health.
How to avoid induction cooker radiation
1. When choosing an induction cooker, choose an induction cooker with relatively good quality. Do not ignore the quality of the induction cooker just because it is cheap. Generally, compared with The quality of famous induction cooker brands is guaranteed and they are safer to use.
2. When using the induction cooker, you should not get too close to the induction cooker. You should keep an appropriate distance. If the distance is too close, the human body will be exposed to more electromagnetic radiation. It is best to keep the distance when using the induction cooker. Above 40cm is the safest.
3. When using an induction cooker, the choice of pots is also very important. Pots made of copper, iron and other materials can absorb a certain amount of electromagnetic radiation during use and reduce the leakage of electromagnetic radiation. Better protect users' health.
4. When using an induction cooker for a long time, you need to choose an induction cooker covered by a metal partition. Placing the induction cooker under the metal partition can effectively reduce the radiation of the induction cooker and block the radiation leakage of the induction cooker. Radiation leakage from induction cooktops with metal partitions is relatively small.
5. When using the induction cooker, try to reduce the use time of the induction cooker. Although the edge radiation of the induction cooker is small, it is still easy to harm the body if exposed to radiation for a long time.
When purchasing an induction cooker, you must choose a regular and well-known brand. Generally speaking, the more formal an induction cooker is, the more stringent its production is and the smaller the relative electromagnetic radiation. In addition, when choosing a pot, choose iron and steel products to reduce leakage. When purchasing an induction cooker, you should ask the seller for an electromagnetic induction intensity test report. Most induction cookers will have this. Use this report to compare and choose an induction cooker with relatively low electromagnetic radiation. Harm of Radiation in Central Control Room to Humans 3
What are the types of radiation in daily life
Radiation is divided into non-ionizing radiation and ionizing radiation.
We are no strangers to non-ionizing radiation. For example, computers, mobile phones, home appliances, communication base stations, etc. all emit non-ionizing radiation. However, non-ionizing radiation has a long wavelength and low energy. Under normal circumstances, it is not enough to cause gene mutation or chromosomal variation, so it can be used with confidence.
But ionizing radiation is different. Ionizing radiation can cause biological damage by changing the chemical state of matter. Ionizing radiation has short wavelength and high energy. Common types include alpha particles, beta particles, protons, neutrons, X-rays, gamma rays, etc. Radiation sickness caused by ionizing radiation causes pathological changes in almost all organs and systems, especially the nervous system, hematopoietic organs and digestive system. Excessive radiation may even cause cancer or cause fetal death and malformations.
Ionizing radiation is commonly used in medical treatment, such as X-rays, CT, and some equipment for radiotherapy. But here is a question: Are X-rays, CT, etc. harmful to the human body? If so, how harmful is it?
Research shows that the human body can withstand less than 100 millisieverts of ionizing radiation at one time and has little impact on the body. Data shows that the global average annual background radiation dose per person is 2.4 millisieverts. The radiation dose of a chest X-ray is 0.01-0.04 millisieverts, and the radiation dose of a cardiac catheterization is only 10 millisieverts. In terms of dose, the amount of radiation from X-ray examination has little impact on the body. If you give up this highly efficient diagnostic technology because of fear of radiation, you will undoubtedly be giving up food because of choking.
Of course, this does not mean that CT and other technologies can be abused. If the dose of ionizing radiation is not well controlled, repeated exposure to ionizing radiation is still very dangerous. Before using CT, you should consider whether it is really necessary. Even if it is used, it should be done in a way that minimizes the exposure of normal tissues. Pregnant women, in particular, need to be cautious when performing relevant examinations because their fetuses are more susceptible to radiation effects.
So, what is the main source of background radiation? How to reduce radiation exposure?
Background radiation mainly comes from cosmic rays, surface radiation and internal radiation.
In fact, the universe emits cosmic rays to the earth all the time, but because the earth's surface is blocked by a thick atmosphere, the amount of radiation falling to the ground is very low. Therefore, if you live at a higher altitude, you will be exposed to stronger radiation. How to avoid cosmic ray radiation is also a difficult problem that needs to be solved in long-term exploration of outer space.
Surface radiation refers to the radiation released by rocks, soil, plants or minerals in nature. There are mainly γ rays released by four radioactive elements: radon, potassium and uranium.
Internal radiation refers to the radiation produced by radioactive substances in the external environment and entering the human body with air and food. Such as smoking. Another example is that bananas contain the radioactive element potassium-40, which may produce internal radiation when eaten into the body, but we can basically ignore this content.
Let me explain here again that in fact, everything in the universe contains radiation, even the water we drink and the food we eat are no exception. However, these doses are small, so we can ignore them.
What really needs to be monitored are nuclear facilities, associated radioactive mines, radioactive material transportation, base station electromagnetic radiation, AC power transmission and transformation engineering electrical radiation, broadcasting electromagnetic radiation and other places, including some home appliances or electronic and electrical equipment. If you have any doubts about the amount of radiation, you can entrust a nationally recognized third-party testing agency, such as Zhongke Testing, to conduct testing.
