Xu Mingren said that all animals, plants and human bodies have the natural ability to absorb radiation, but at present, there is no research to prove that a certain species has a particularly strong ability to absorb radiation. Cactus lives in a place with strong sunshine in the desert. The author of the rumor may regard "radiation energy" as radiation, and in the case of taking it for granted, he thinks that a pot of cactus is placed in front of the computer to absorb radiation and reduce the harm to the human body.
Cactus is a succulent plant that likes sunshine. In order to reduce the evapotranspiration of water, the leaf surface area is reduced and evolved into a needle, which is to adapt to the natural environment. Xu Mingren said that the appearance of cactus is to resist the damage of sunlight and ultraviolet rays, which is different from the radiation generated by computer screens or other electrical appliances. The so-called radiation is an invisible wave, including α β γ rays, of which γ rays are the strongest and have the ability to penetrate any organism, and will destroy the DNA of cells, which will seriously cause mutations. Sunlight is a kind of radiation energy, which will heat up like candlelight and will not produce immediate effects on the human body. Therefore, the content of the rumor regards cactus as a tool to resist radiation, which is unfounded.
Xu Mingren said that radiation is a kind of energy wave that goes straight. At present, there is no matter that can make radiation turn. Therefore, the statement of absorbing radiation should be changed to resisting radiation. The environment in which we live is already full of all kinds of radiation, but it is only numerical. At present, the radiation and electromagnetic waves emitted by electrical appliances are actually very slight. Perhaps people who don't understand it will panic because the radiation can't be seen, touched or smelled.
In front of the desktop computer of the Department of Horticulture of National Taiwan University, there are all kinds of documents and experimental equipment, but no cactus can be seen. Xu Mingren said with a smile that they have never heard of this saying. He thought it might be a marketing move of cactus merchants. He suggested that students and office workers who often use computers should set up pots of cactus to green their beautiful desktops, which can really relieve eye fatigue, but if they want to reduce the harm of radiation to human body, they should buy a screen goggles.
Ye Changlin, chief of the Radiation Environment Management Office of Jiangxi Environmental Protection Bureau, believes that the earth itself is a large magnetic field, and human beings live in electromagnetic radiation all the time. People themselves are radiators, constantly absorbing radiation and constantly emitting radiation. At present, it is widely rumored in society that some plants can absorb electromagnetic radiation, and the above arguments alone are not enough to confirm it. Therefore, it is understandable that flowers and plants are placed in front of the computer, which varies according to people's hobbies; Whether this can significantly reduce radiation, there is no formal research results, not to mention whether computer radiation has an impact on the human body and how harmful it is. It is really wrong for merchants to take the opportunity to speculate on flowers to mislead consumption and even raise prices.
Chief Ye Changlin gave some advice and suggestions to the "radiation-fearing people". First of all, it is particularly important to maintain a good mental state. Don't talk about it. A good mental state is far more beneficial to health than buying a potted flower and wearing a "radiation protection" suit. Secondly, because of the "cumulative effect" of electromagnetic radiation, both pregnant women and white-collar workers in the company should not sit in front of the computer for too long, and should often walk around, which will be beneficial to health. Most of the propaganda about the harm of electromagnetic radiation on the Internet is exaggerated and should not be trusted. In addition, the electromagnetic radiation emitted by the mobile phone at the moment of connection is much higher than that of the usual call, so it is a good idea to keep the mobile phone away from the head for 2 seconds before answering, and it is also a good idea to answer with headphones.
