Nowadays, many people do not leave their cell phones in their hands, that is, when they sleep at night also put it on the pillow. There is a folklore that if you sleep too close to your cell phone, its radiation effect may cause cancer, whether this statement is scientific has not seen a clear answer. Research has found that there are two types of radiation that we may be exposed to in our daily life, one is ionizing radiation (e.g. nuclear radiation, hospital X-ray, CT, PET and other examination equipment); the other is non-ionizing radiation (e.g. electromagnetic fields generated by cell phones, WiFi, ultraviolet light, microwave ovens, refrigerators, etc.). Among them, only exposure to a certain amount of ionizing radiation is likely to cause cancer. Non-ionizing radiation, on the other hand, is not carcinogenic because its radiation energy is very small and not enough to change the chemical properties of substances. To introduce you to an article, it tells us that professional research results show that most of the radiation we are widely exposed to daily is non-ionizing radiation, and its effect on us is only to produce thermal effect, you just feel hot after long-term exposure, which is not enough to produce harm to our body. Does sleeping with a cell phone at the bedside cause cancer? Although the World Health Organization (WHO) has classified cell phone radiation as a 2B class carcinogen, which means it may cause cancer, there is no sufficient evidence from animal and human experiments to prove its carcinogenicity. Such as fiddleheads also belong to this category. The fern can be eaten normally, how can the phone can not play? And although cell phones have radiation, the dose of radiation is very low (not enough to reach the amount of cancer-causing), and is far from the radiation dose of sunlight. We wear clothes in the summer sun for a while, the amount of radiation received are dozens of times higher than holding the phone to sleep. If sleeping with a cell phone at the head of the bed can cause cancer, then we have long been the sun shot into the slag. So, when you sleep, where to put your phone, where to put it will not affect your health. Is it okay to sleep while charging? Once saw the news: last March, Ningbo Mr. Wang bought a brand of cell phone, 2049 yuan, in June this year, the phone on the bed at night suddenly burned …… remember, cell phone charging, pay attention to these! For your personal safety, of course, it is not recommended to sleep while charging, not afraid of ten thousand, only in case, in case of battery aging, in case of a bomb! That will be too late to regret … What other radiation in life? Most people are “talk about radiation”, but not all radiation is harmful. In our lives, there are two kinds of radiation: ionizing radiation such as nuclear radiation, hospital X-rays, CT, PET and other screening equipment; non-ionizing radiation such as cell phones, WiFi, ultraviolet light, microwave ovens, refrigerators and other electromagnetic fields. Among them, only the intake of a certain amount of ionizing radiation is likely to cause cancer. As for non-ionizing radiation, the amount of radiation is very small, which is not enough to change the chemical properties of substances and therefore is not carcinogenic. Most of the radiation we are widely exposed to on a daily basis is non-ionizing radiation. The effect of non-ionizing radiation on us is only the thermal effect, which makes us feel hot and is harmless to our body. So usually when using electrical appliances including cell phones (qualified products from regular manufacturers), there is really no need to worry about radiation. In addition, in the hospital to do such as X-rays, CT examinations, indeed, we will be exposed to ionizing radiation. However, as the old saying goes, “Talking about toxicity aside from the dose is a hooligan”, doing these exams 1 to 2 times a year will not affect your body. So, when your doctor asks you to do such tests, don’t refuse because you will be exposed to ionizing radiation. What are the methods of radiation protection? First of all, let’s dispel the rumor: plants can absorb radiation? False! Cactus can survive in conditions of water shortage, high temperature and strong sunlight. But, in our room, cactus can only be a pot of green ah. Say what cactus greenery similar plants can be used to prevent reduce computer radiation? Too false …… maternity radiation suit can prevent radiation? False! Pregnant women do not need to wear radiation protection clothing. There is no evidence that daily non-ionizing radiation causes an increase in the rate of miscarriage and fetal malformations in pregnant women, nor does it cause low birth weight in newborns; there is only very weak evidence that some daily non-ionizing radiation is associated with the onset of certain diseases, but a causal relationship cannot be proven. So, is there anything that can be done to prevent radiation? Practically speaking, we do not need to prevent radiation, and there is no way to prevent it. Because most of our daily life, we are exposed to non-ionizing radiation, and we know that non-ionizing radiation is not harmful to us, so why do we need to prevent it? Besides, non-ionizing radiation is everywhere, anything that emits heat will produce it, such as sunlight, computers, cell phones, etc. We just have to be careful about ionizing radiation. We just have to pay attention to the prevention of ionizing radiation, usually medical X-rays, CT, etc. However, when doing medical examinations, according to the normal frequency and standard operation, there is also basically no effect on the human body.
