Discussion on Radio Radiation

The reception and transmission of radio stations will definitely cause radiation problems. As you may know, as long as the power passes through the wires, the magnetic waves will be only large or small. The current of ordinary wires and high-voltage lines will also cause the radiation of the magnetic field, but the way of current dredging is different. Civil wiring will not cause damage to human organs unless it is very high voltage (tens of thousands of volts) and is 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. Use low-power transmission as much as possible to listen more and talk less, reducing the radiation to you. 2. Especially for the mobile phone, remember to use an external antenna A: increase the receiving and calling effect B: isolate the radiation. The radiation when using the hand table is very close to the head. The power of 5W is enough to cause slight damage to your brain. The cumulative radiation that changes slightly after using it for a long time will reflect.
3. It is strongly recommended that the HAM using the hand platform must be equipped with outdoor antennas (normal seedlings) in cars and homes.
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.
5According 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 prescribed by the state (this is easy to do). Since the car is a metal body, it is relatively safe.
6. Regardless of the vehicle platform or the hand platform, try to move the antenna to the outside such as cars and houses.
