Cactus and orchids cannot protect against radiation, stop being misled

Radiation protection can be achieved in two ways: one is blocking, the other is absorption. We can use the principle of the shielding phenomenon to make a shield around an object with a conductor so that external electromagnetic fields cannot enter. Another method is to use materials that absorb radiation to absorb the radiation and protect the object. Cactus can absorb radiation. Some office workers in office buildings like to place a pot of lush green cactus next to their computers. Apart from personal preference, most people value the cactus for its special ability to “protect against computer radiation.” However, next to the computer in the office of the Horticulture Department at Beijing Agricultural College, reporters rarely saw cactus. Professor Yao Yuncong of the Horticulture Department said that cactus grows in deserts with intense sunlight and can resist damage from sunlight and ultraviolet rays. But what sunlight produces is a kind of “radiant energy,” which is different from the radiation rays produced by computer screens or other electrical appliances. Radiation rays are a kind of energy wave that travels in a straight line. At present, no substance can make radiation rays turn, and the claim of “absorbing” radiation rays is obviously inaccurate as well; it should be changed to “blocking.” At present, no research report has demonstrated that cactus is superior to other plants in its ability to absorb radiation rays. Therefore, placing a pot of cactus next to a computer to absorb radiation and reduce harm to the body is entirely inferred and has no scientific basis. Although placing a pot of cactus in front of a computer cannot block radiation rays, the green color can relieve eye fatigue and relax the mind, so for computer users who strain their eyes and minds all day long, it is indeed a good way to “nourish the eyes.”        Compared with placing green plants, drinking a little green tea is a simpler and easier trick for resisting computer radiation. A study from the University of Hawaii in the United States once showed that drinking more green tea plays an important role in preventing radiation. Tea leaves contain more lipopolysaccharides, which can improve the body's hematopoietic function. After lipopolysaccharides are introduced into the human body, they can enhance the body's nonspecific immunity in a short time, thereby effectively preventing radioactive substances from invading the body and having a significant protective effect on hematopoietic function.       It can be seen that compared with cactus, green tea is the “expert” in protecting against computer radiation. In addition, mung bean soup contains substances that help excrete toxins from the body and accelerate metabolism and can also effectively resist various forms of radiation pollution. It should be noted that because electromagnetic radiation has a “cumulative effect,” one should not sit in front of a computer for too long and should move around often, which will be beneficial to health.
