Does the TV set have radiation? How is the penetration?

TV: Less negative oxygen ions will cause discomfort.

You really shouldn't get too close when watching TV. Being too close will not only hurt the eyes, but also when the CRT is activated, the cathode of the TV will emit high-energy electron beams. When these electron beams violently hit the fluorescent substance on the inner wall of the screen, images will be displayed on the screen, but penetrating X-rays will also be produced.

There'd better be a time limit for watching TV. If you want to watch it for a long time, remember to leave the scene at least once an hour. The seat is at least two meters away from the TV, and it is best to install a protective screen. When the TV screen displays images, it will also release a large number of positive ions, which will absorb negative oxygen ions in the surrounding air like magnets, thus greatly reducing the negative oxygen ions in the indoor air. Being in a state of lack of negative oxygen ions for a long time makes people prone to headache, chest tightness and loss of appetite. People who watch TV for a long time should also pay attention to the indoor air circulation.
