A so-called "warning microblogging," this report "subway security machine, security doors and other harmful health, every day by radiation, life should be shorter, especially in the security machine mouth when the package does not open the curtain!" Widely spread in the network , So that users are panic.

    Today, China has opened more than 10 subway cities, all the population of a second-tier cities, only Beijing daily subway travel to more than 10 million people, the subway security for a long time, but the safety of security equipment, the public knows it Rarely, security doors, security machines, metal detectors and other equipment is the existence of radiation? Chengdu Metro recently related staff, said the security device less than the phone. Chengdu Metro in the work of more than three years of Chen told reporters that he was close to the daily access to the security device, but did not feel wrong.

    Senior security equipment manufacturer Shenzhen Branch of the Shing Technology Co., Ltd. localhost \ / enzkls Chen chief engineer standing in a professional point of view, but also easy to explain to us the security machine imaging principle: X-ray security machine is the use of X-ray imaging through the object, the image and then through the computer processing, the computer screen shows an image can be identified to assess the safety of the object.

    China's Atomic Energy Science researcher Xiao Xuefu said that the security machine radiation is negligible, and will not adversely affect human health. Xiao Xuefu said that China's "basic standards for ionizing radiation protection and radiation source safety" (GB18871-2002) provides that the public by the artificial radiation of the average effective dose of the estimated value can not exceed 1 ho Hewitt. According to scientific measures can be drawn, even if the passengers every day in the need to take the subway, the normal through security, the radiation is far from the value of this value. In addition, security doors, security machines, hand-held detectors on pregnant women and the impact of fetal birth can also be ignored. Radiation-induced deformity There is a threshold of about 100 Hohhot, and the radiation of the MTR is very low compared to this. The same way through the X-ray lamination of the baggage will be subject to a certain dose of radiation, but this high-frequency electromagnetic waves in the object through which it does not exist radiation residue, because after the X-ray security device does not affect people's food The

    It can be seen that passengers in the security door, security machine will not cause harm, X-ray security machine will not adversely affect the goods, the so-called "security is harmful to health," said it is not true. Of course, as the Metro staff reminders, passengers should be in accordance with the order security, should not be hand into the security machine to take the package, otherwise it may cause some harm.
