That cactus prevents radiation is wrong?

Radiation We can't expect cactus to resist radiation
It is true that cactus can prevent radiation, but what it resists is optical radiation instead of electromagnetic radiation. If you put the cactus in front of your computer, it will also be damaged by electromagnetic radiation.

There is a saying gong like: cactus can survive in the desert where the ultraviolet radiation is very strong. It has the characteristics of absorbing ultraviolet radiation, but it is of no use to resist radiation released by cell phones and other electronic products.
When people are sitting in front of the computer screen, the cactus will not resist the radiation wave even if they can due to rectilinear propagation of the radiation waves. From a biological standpoint, green plants have the ability to absorb radiation. But the radiation-proof effect of cactus has no basis, it is more of everyone's psychological effect.
As long as you are sitting in front of the computer, the radiation is inevitable. A cactus is far from enough to reduce the radiation damage caused to human body.
But it is veritable that cactus is a natural oxygen bar. Most plants have photosynthesis in the daytime, absorbing carbon dioxide and releasing oxygen. At night, with respiration, absorb oxygen, carbon dioxide. For some other plants, such as cacti will release carbon dioxide in the daytime and absorb carbon dioxide and release oxygen at night, putting a cactus inside the bedroom will supply oxygen which is conducive to sleep. Don't look down upon a cactus, It is very good for dust adsorption. Placing a cactus in the room, especially aquiculture prickly pear (for aquiculture prickly pear is more clean and environmentally-friendly ), can help purify the air.
