Chengdu Shuangliu Airport security door in radiation airport security "radiation" door – Chengdu Shuangliu Airport by X ray transmission body weak photon human security apparatus – biomedical engineering experts believe that the radiation dose should be very low, but with special populations such as pregnant women prompt source: Southern Metropolis Daily       09 2016 29 August             AA19     Edition:   Author: Wang Daobin   Chengdu Shuangliu Airport, recently in the social media as "Red Net", the reason is the explosion of red photon airport using "human security instrument". Users believe that the human body security instrument can be used to penetrate the human body X rays, but did not put a significant position in the ionizing radiation warning. Ma Jianhua, a professor of Biomedical Engineering at Southern Medical University, has just flown back to Guangzhou from Sichuan. Ma Jianhua said that at present the Shuangliu Airport and other public transport facilities to the application of these devices, the estimated radiation dose is very low, because this kind of radiation will have a cumulative effect, and low dose of penetrating radiation, also need to caution, "especially for special populations such as pregnant women." By the human security instrument swept the public worried about the X radiation in Guangzhou at 2:30 on September 28th, Guangzhou citizens strict security checks at Chengdu Shuangliu Airport. Yan introduced, because of the reasons for the work, to fly back to Chengdu from Guangzhou. When accept the security, she found that Chengdu’s Guangzhou airport security machine and the machine is different, Chengdu has a security door about two meters long track, passengers on the two steps after boarding the track, keep your feet still be transported to the other end of the track. On the track, you can stand three adults at a time, so the security is very fast. Ms. Yan recalled, near the entrance did not see a clear hint of ionizing radiation, did not notice the security personnel holding security equipment for passenger security. In the airport, Ms. Yan saw a circle of friends circulated "how to evaluate the Shuangliu Airport and other places using X ray projection body" weak photon human security apparatus "of a text, they realize they just after X radiation. "I am really angry, if there are women of childbearing age to accept security, the impact on the fetus, then we can go to the airport?" Yan said that in any case, the airport at least to give passengers the right to know, rather than their own secretly engage". It is reported that this is the entrance of the airport security checkpoint, is the only way to enter the airport". Be sure that the device is an exogenous radiation, Professor of Biomedical Engineering, Southern Medical University, Professor Ma Jianhua, also just flew back to Guangzhou from Sichuan. As a long-term study of human medical imaging experts in the field, after the Shuangliu Airport "weak photon human security apparatus, he instinctively wants to see the imaging effect of the instrument after simple sweep. But this is a kind of occupational disease like action, was blocked by security personnel. In fact, similar security equipment, 9, after the United States has been widely used in the 11. It is only in China相关的主题文章:
