This is a long-standing joke in the mouths of many "health masters": putting a cactus next to the computer can also absorb radiation. But the fact is, when you want to search for any papers and experiments that prove that this statement is alive, you can't find any basis to support this statement. So is this statement out of thin air? Not exactly. The deduction path of this rumor is probably just that the cactus below is very vital, and the desert can survive under high temperature and strong light without water-sunlight contains a lot of ultraviolet rays, so it can resist ultraviolet rays-so it is natural to resist computer radiation. Although both CRT monitors and LCD monitors have a small amount of radiation, cactus or cactus can resist the damage of sunlight and ultraviolet rays, but it can't turn the radiation, and nothing has this ability. So it is nonsense to say that cactus can resist radiation, in fact, it is for itself. Even if your computer has radiation, it is useless to put any cactus. Does that mean cactus is useless? No, imagine that when you face the computer for a long time and turn to look at a pot of green plants, you will still feel refreshed. Moreover, oxygen released by photosynthesis of green plants can also purify indoor air. And it's easy to grow and doesn't need much care. So putting a cactus next to the computer still has many benefits. Office workers in office buildings, apart from their personal preferences, love to put a cactus next to their computers. Most people value cactus's special ability to prevent computer radiation. However, the reporter rarely saw cactus next to the computer in the office of Horticulture Department of Beijing Agricultural College. Professor Yao from the Department of Horticulture said that cactus grows in a desert with strong sunlight and can resist the damage of sunlight and ultraviolet rays. But sunlight produces a kind of "radiant energy", which is different from the radiation produced by computer screens or other electrical appliances. Radiation is a linear energy wave. Nothing can make it radiate at present.
