汉英对照:
Chinese-English Translation:

是的,电脑的确有辐射。而且各个部件的辐射程度都不同。电脑辐射主要就是指电磁辐射,电磁辐射通常以热效应,非热效应和刺激对机体产生生物作用。

Yes, computers do radiate. And the radiation level of each part is different. Computer radiation mainly refers to electromagnetic radiation, which usually produces biological effects on the body by thermal effect, non thermal effect and stimulation.

电脑辐射主要就是指电磁辐射,电磁辐射通常以热效应,非热效应和刺激对机体产生生物作用。自然界中的一切物体,只要温度在绝对温度零度以上,都以电磁波的形式时刻不停地向外传送热量,这种传送能量的方式称为辐射。物体通过辐射所放出的能量, 称为辐射能。辐射按伦琴/小时(R)计算。

Computer radiation mainly refers to electromagnetic radiation, which usually produces biological effects on the body by thermal effect, non thermal effect and stimulation. All objects in nature, as long as the temperature is above absolute temperature zero, transmit heat to the outside constantly in the form of electromagnetic wave, which is called radiation. The energy released by an object through radiation is called radiant energy. Radiation is calculated as roentgen / hour (R).

专家研究发现,其实凡是用电的日常家用设备都会产生电磁辐射,对人体有无危害,最重要的是要看辐射能量的大小。根据国际辐射防护协会和国际劳工组织的规定,电磁场的安全强度是 0.11-0.3 微特拉(这是 24 小时接触计算机时的电磁场安全限),低于此强度对人体没有危害。 一些专门研究机构测试过计算机的电磁场强度,结果发现,紧贴荧光屏处电磁场强度为 0.9,但离开荧屏约 5 厘米处,强度不到 0.1,再远一点至 30 厘米处(这是计算机操作者的身体与荧屏之间的习惯距离), 其强度几乎无法测 出。此外,空间中的电磁波确实是无处不在的,但是在一般情况下,这种电磁辐射的强度很小, 不会对人体健康造成伤害。中国颁布的《电磁辐射防护规定》,规定了电磁辐射污染的设备和对人员影响的标准限值,只有当电磁波达到一定强度的时候,才需要重点保护。

Experts found that in fact, all the daily household electrical equipment will produce electromagnetic radiation, whether it is harmful to human body, the most important thing is to see the size of the radiation energy. According to the regulations of the International Radiation Protection Association and the international labor organization, the safe intensity of electromagnetic field is 0.11-0.3 μ TLA (this is the safe limit of electromagnetic field when contacting the computer for 24 hours), which is lower than this intensity and does no harm to human body. Some special research institutions have tested the electromagnetic field intensity of the computer. The results show that the electromagnetic field intensity is 0.9 at the place close to the screen, but it is less than 0.1 at the place about 5cm away from the screen, and it is almost impossible to measure the intensity at the place a little further to 30cm away (this is the customary distance between the computer operator’s body and the screen). In addition, the electromagnetic wave in the space is indeed ubiquitous, but in general, the intensity of this electromagnetic radiation is very small, which will not cause harm to human health. The regulations on electromagnetic radiation protection promulgated by China stipulates the standard limits of equipment and personnel impact caused by electromagnetic radiation pollution. Only when the electromagnetic wave reaches a certain intensity, it needs to be protected.

电脑辐射导致脱发

Hair loss caused by computer radiation

辐射不是导致脱发的头号因素。电脑使用时间过长是导致脱发的关键所在:精神高度集中使用电脑,时间过长大脑兴奋度会增高,内分泌会发生紊乱,与毛囊相连的皮脂腺分泌过盛会导致毛囊栓塞,头发的营养供应出现障碍,发质会变脆,头发便会脱落。对于轻微脱发,可以通过减少电脑的使用时间和调节生活方式来缓解。

Radiation is not the number one cause of hair loss. The key to hair loss is that the computer is used for a long time: when the computer is used intensively for a long time, the brain excitation will increase, the endocrine will be disordered, the sebaceous glands connected with the hair follicle will be secreted excessively, which will lead to the hair follicle embolism, the nutrition supply of the hair will be blocked, the hair will become brittle, and the hair will fall off. For slight hair loss, it can be alleviated by reducing the use time of the computer and adjusting the lifestyle.
