Cactus orchids are not protected against radiation _ succulent plants

Radiation protection can be realized in two aspects.

One is to prevent the other is to absorb. We can use the principle of shielding phenomenon to shield the object with a conductor so that the external electromagnetic field can not enter.

Another method is to use materials that absorb radiation to absorb radiation to protect the object. Cactus can absorb radiation. Some office workers like to put a pot of green cactus next to their computers. in addition to their personal preferences, most people value the special ability of cactus to protect against computer radiation.

But the reporter seldom saw the cactus next to the computer in the office of the horticulture department of Beijing Agricultural College.

Yao Yuncong, a professor in the horticulture department, said that cacti grow in deserts with strong sunshine and can withstand the damage of sunlight and ultraviolet rays. But what is produced in sunlight is a kind of "radiant energy", which is different from the radiation produced by computer screens or other electrical appliances. Radiation is a kind of energy wave that travels in a straight line. at present, there is no substance that can turn the radiation, and the statement of "absorbing" radiation is obviously not accurate and should be changed to "resist". No study has yet demonstrated that the cactus has a better ability to absorb radiation than other plants. Therefore, it is completely inferred to put a cactus next to the computer in order to absorb radiation and reduce damage to the body, and there is no scientific basis. Although a pot of cactus in front of the computer cannot resist radiation, green colors can relieve eye fatigue and relax the spirit, and it is a good way to "please the eyes" for computer people who are tired and tired all day.

Compared with putting green plants, drinking green tea is a simpler and easier way to ward off computer radiation. Studies from the University of Hawaii in the United States have shown that drinking more green tea plays an important role in preventing radiation. Tea contains more lipopolysaccharide, which can improve the hematopoiesis of the body. After lipopolysaccharide is injected into the human body, it can enhance the non-specific immunity of the body in a short time, which can effectively prevent the radioactive material from invading the body and has a significant protective effect on hematopoiesis.

It can be seen that, compared with the cactus, green tea is the "master" of preventing computer radiation. In addition, mung bean soup contains substances that help excrete toxins in the body and accelerate metabolism, and can also effectively resist various forms of radiation pollution. It should be noted that due to the "cumulative effect" of electromagnetic radiation, the time spent sitting in front of the computer should not be too long and should be moved frequently, which will be beneficial to health.
