Everything in nature, as long as the temperature is above zero in absolute temperature, is constantly transmitting heat in the form of electromagnetic waves. This way of transmitting energy is called radiation. The energy emitted by an object through radiation is called radiant energy. Radiation is calculated in roentgen/hour (R).
An important feature of radiation is that it is "equal." Regardless of the temperature of the object (gas) radiating outward, the object A can radiate to the object B, and B can also radiate to the armor. This is different from conduction, which is one-way.
How far is radiation from us? In our living environment, radiation is everywhere!
Household appliances: TV, refrigerator, air conditioner, microwave oven, vacuum cleaner, computer, etc.
Office equipment: mobile phones, computers, photocopiers, electronic equipment, medical equipment, etc.
Home decoration: marble, laminate flooring, wall paper, paint, etc.
Surrounding environment: TV (broadcast) signal transmission tower nuclear radiation, etc.
Natural environment: sunspots, etc.
The so-called radiation refers to the phenomenon that radio waves generated by high-frequency oscillation of the circuit are emitted into space. Radiation of a certain frequency and intensity has an effect on the body. The batteries we use are generally chemically and physically altered, and there is no RF generated, so there is no radiation.
The phone will generate a relatively large amount of radiation when making a call. However, as long as the brand mobile phone radiation of the regular big factory is within the scope of the state, it will not cause great harm to people.
However, long-term in such an environment will inevitably have an impact, because the tooling for detecting the battery will generate radiation at the time of detection, but will not affect fertility.
The battery power of the mobile phone is low, and the lack of power causes the system to actively increase the transmission power, resulting in a multiplication of radiation, that is, even when the signal is relatively good, since the mobile phone is to maintain normal operation under low power, its transmission The power is much larger than when the power is sufficient, which increases the existing radiation. This time using a mobile phone, damage to the phone and battery!
The battery is not radiated, because the battery is made of carbon, manganese, zinc or lithium. There is no radioactive element at all. The atomic number of cadmium is 48. The atomic number of the radioactive element is greater than 84. There is no radiation, but it will cause poisoning, so do not disassemble the battery.
The discharge reaction is a general chemical reaction. There is no change inside the atom, there is no radiation, so some people say that the battery has radiation is wrong.
When the battery is in use, the electromagnetic wave generated by the current will be weakly radiated, but it can be ignored, and it has little effect.
Heavy metals such as mercury and cadmium in batteries can cause poisoning and the most serious water pollution, so don't throw batteries. The famous Japanese Minamata disease is caused by this reason.
A healthy person can withstand a short 5000R load, but only 700R is enough to cause a healthy person to be fatally threatened, but each person's physical resistance is different, and each person will have different degrees of symptoms. Generally, it is caused by electromagnetic radiation pollution, which may cause problems such as headache, insomnia, and arrhythmia. At the same time, it may affect some people's eyes, such as decreased vision, skin diseases, etc., and may cause cancer. For pregnant women who may cause miscarriage, the elderly who have installed a cardiac pacemaker should pay special attention. At the same time, the ability of different people or the same person to withstand electromagnetic radiation at different ages is different. Even in the case of exceeding the standard, it does not mean that everyone will get sick. Therefore, it is not necessary to have a "grass" for electromagnetic radiation. However, for the elderly, children, pregnant women or patients with cardiac pacemakers, people who are sensitive to electromagnetic radiation and those who work in the environment of excessive doses of electromagnetic radiation should take precautionary measures.
