Introduction of Radio Radiation
As long as the power supply passes through the wire, it will cause magnetic waves. The current of ordinary wires and high-voltage wires will also cause the radiation of the magnetic field. However, due to the different methods of current dredging, ordinary civilian lines will not cause damage to human organs unless the ultra-high voltage ( Tens of thousands of volts) and very close to where you live. At present, the radio stations and ordinary wires used by our majority of HAM are not the same thing (not much explanation). Simply speaking, it is a small microwave oven (determined by its specific wavelength), so it has long been working in communications, military, post and telecommunications systems. Personnel exposed to radio and radar have special radiation welfare allowances.
For us HAM, we must pay attention to 2 points:
1. Especially for the mobile phone, remember to use an external antenna A: increase the receiving and calling effect B: isolate radiation. The radiation when using the hand table is very close to the head, and the power of 5W is enough to cause slight damage to your brain. If you use it for a long time, the cumulative radiation will change slightly. You will reflect it. If you ask your wife I understand.
2. Regardless of the vehicle platform or the hand platform, try to move the antenna to the outside such as cars and houses.
3. It is strongly recommended that the HAM using the hand platform must be equipped with outdoor antennas (normal seedlings) in cars and homes. You can check the articles I wrote before on the Internet.
4. The use of the HAM in the car and the house is also an irresponsible injury to your family, especially to warn friends who want to avoid checking the radio station of the association, remember not to put the antenna in the trunk of the car, because The car body is actually connected, and your head will shine for a long time.
5. Use low-power emission as much as possible to listen more and talk less, reducing the radiation to you.
6. According to theoretical calculations and practical experience, the relative radiation of ordinary seedlings is 3 meters away from the human body or the residence is within a reasonable range stipulated by the state (this is easy to do). The seedlings of the car are best placed on the top of the car and then at the rear and front. , Because the car is a relatively safe point of the metal body.
