Shenzhen Metro X-ray security machine alleged illegal continued: Public Security Bureau to remain silent

6 15 morning, Shenzhen Huaqiang Road Metro station, passengers put the package through security machine.
6 15 morning, Shenzhen Huaqiang Road Metro Station, screeners at work.
6 15 morning, Shenzhen Huaqiang Road Metro Station, queuing for screening.

Shenzhen Metro 286 X-ray security machine is illegal to set the news was revealed, the most interesting living environment in Shenzhen City Council how to deal with these machines? Shenzhen Public Security Bureau as the owner and user of the machine, for illegal use of X-ray screening machine explain this? Yesterday, the Shenzhen Commission does not stand living environment will be how to deal with the machine, the Shenzhen Municipal Public Security Bureau is to remain silent.

At the same time, 286 X-ray machine fate arouse public concern. Southern reporter yesterday subnet in Austria and South have launched an online community on the fate of the X-ray screening machine attitude surveys. The results showed that 85% of users choose not to retain the X-ray security machine. Only 6% of users choose to continue using the X-ray machine.

1 Q

government to break the law?

public security departments, as law enforcement, how can not comply with the law, break the law? Shenzhen City Public Security Bureau is 286 bus X-ray baggage screening machine owner, user security company in Shenzhen. As the use of X-ray machine who needs to take the initiative to the environmental protection departments for the use of X-ray machine, apply for an environmental assessment, apply for a permit. However, according to Shenzhen, nuclear and radiation management center, said throughout the Shenzhen Public Security Bureau did not make returns.

Southern reporter contacted again yesterday at the Shenzhen Public Security Bureau Public Relations, the department said a staff reporter for the South are still leading in the hands of the interview letter, not yet approved. Southern reporter from the beginning on July 28, a total of three interviews with Municipal Public Security Bureau issued a letter. Staff said that leadership has seen the interview letter, but not for approval.

from July to now, why not see nuclear and radiation monitoring department of the subway station the illegal use of X-ray machine? Southern reporter contacted again yesterday of nuclear and radiation management center, management center Hanke Chang investigation confirmed no action yet, but this is an internal process, can not tell the media. Hanke Chang said, “there are some things with the regulations, in reality, there are some (contradictory), for example, regulations to obtain a permit, (but it itself) is a temporary work, short-term use.” Hanke Chang recognition, according to relevant laws and regulations, as long as necessary to obtain a permit the use of, and approval procedures are the same. The next step is to enforce the law, when he said to the media to know. He also said that based on open government information regulations, is not anything to be with the media said.

2 Q

leakage radiation is safe?

South is a reporter with the Shenzhen Centre for Nuclear and Radiation Management staff from on-site inspection of the data, machine operation, baggage screening machine staff on the location of the export of lead curtain 1 hour acceptable do a chest X-ray radiation dose received radiation doses of 1/100 to 1/50.

Although the subway station X-ray radiation exposure than the lower, but let Metro screeners Kobayashi (a pseudonym) some not reassuring, “Every day we X-ray machine in the subway next to security, training, they also did not tell us how to protect themselves when the radiation leak”, leaving Kobayashi disturbing is that many screeners will put his hand to direct X-ray machine inside the package directly to the passenger out.

“doing harm to the body”, the Second Hospital of Shenzhen City, Dr. Xia Jun, director of radiology, said that if the hand directly into his X-ray machine, according to the equivalent of a direct X-ray. Occasionally good, if too frequent, rays will kill the body’s white blood cells, may lead to leukemia risk. Even more frightening is that this effect is not immediate, but gradually emerged, according to the current level of medical technology, was also unable to immediately determine the extent of radiation. Xia said that because the screeners did not readily portable radiation dosimeters, so it can not be subjected to radiation daily statistics, the value of how much radiation, “is probably a problem occurring in the future, could get no evidence of substantial rights.”

yesterday, “Nanfang Dushi Bao” reported a security X-ray radiation leakage of information exist, many pregnant women call up, through the X-ray machines will not affect the intra-abdominal baby? Xia said that although the radiation is not direct exposure to the mother’s abdomen, but opened with a lead time, there may be some problem of the reflected rays. Even if the RC has been awarded certification of people, if not take measures to bring the lead, still have radiation leaks. If you often get in the X-ray machine next to the package, the public body may have some bad effects, it is not recommended for pregnant women and children and senior citizens in this stay.

Occupational Disease Prevention Hospital Dr. Wang said that ordinary people a year have to accept the artificial limits of radiation, is 1mSv, the equivalent of 1000μSv, X-ray baggage machine is 10 cm entrances place to be 1000 hours the amount of radiation received.

3 Q

security machine to go to the left?

With the departure of the last batch of screeners, Shenzhen Metro is to retain the X-ray security machine led to users of discussion. Yesterday the head track to do an interview, said that under the management of structured contraband can not be brought into the subway, the Grand Canal after the end of high frequency over-machine inspection is no longer sustainable, but there may be a low-frequency sampling. X-ray screening machine you want to keep it? The official said, to retain, they are suspicious objects can pass X-ray examination. But as of yesterday, not yet finalized subway security multi-sector specific programs.

network continued to set off for the subway security is hot, most of the users objected screened, and said so “will not make anything, and time-consuming.” In fact, over the Grand Canal during the machine security, users are questioned, a huge subway traffic to high-frequency security has become a very difficult thing.

Southern reporter learned from the track to do the Shenzhen subway, running after the number has dropped slightly in the Universiade, is currently close to 200 million passengers/day. 118 sites in the subway, the busy peak hour access to the station number as high as 2 million people. It is reported that the Lo Wu Station, Old Street Station, Huaqiang stations, out of 20,000 passengers/hour, while the number of people into the gates of 1 million person/hours.

Shenzhen friends “EX-SKY” proposed subway stations security machine, who would bear the cost? A machine at least two people, the machine needs 286 572 people, according to a 1000 dollars a month basic wage, the minimum wage for each moon you need 572,000 yuan.

At the same time, X-ray security machine, but there is a fatal flaw, users “APPLEDOG” said security checks of passengers luggage machine just will not check the passenger’s body, the passengers in order to bring prohibited items, too simple, can be hidden in the body.

4 Q

machine security posts without rules?

Southern reporter consulted experts, confirmed that accreditation is to ensure that X-ray baggage screening functions are safe to use, and ensure that the environmental impact of the controllable range. But do not obtain a permit, the machine will not affect the amount of radiation leakage, obtain a permit before and after, the machine will not change the amount of radiation leakage.

inter alia, the approval process mainly for the use of radiation devices, protection, and to inspect, to ensure that no security incidents, to ensure that waste produced by radiation device can be effectively addressed, will not harm the environment.

The Shenzhen subway station X-ray baggage screening machines can be approved, obtain a license, but also environmental protection department of Shenzhen-site testing and inspection.

and this study is very comprehensive, in accordance with State Environmental Protection Administration issued a “security clearance of radioisotopes and radiation device management approach”, which requires use of subway stations need to have X-ray screening machine a number of conditions, which Article XVI, first and foremost personnel requirements, radiation work unit should have a college education with full-time or part-time technical staff responsible for radiation safety and environmental management; list of key positions based on radiation safety, radiation safety should be the establishment of key positions , and the job should be held by a registered nuclear safety engineer. Other staff such as in radiation safety and radiation protection must be expertise and relevant laws and regulations of the training and assessment. Also need to have a range of other security measures, protective equipment, pollution monitoring instruments, a sound radiation emergency measures to have the disposal of radioactive waste, waste water, solid waste capacity and programs.

only with this series of conditions, subway security X-ray machine can be employed. Subway station in Shenzhen X-ray machines apparently are still far away from these requirements.

correspondent field of radiation detection value is not high

Southern correspondent based in Shenzhen Centre for Nuclear and Radiation Management staff to the subway station on-site inspection, the machine side of the machine from the security unit at the surface of 5cm to 10cm, with a hand-held detection equipment staff to get the data 0 .1 μSv/h to 0.2μSv/h, the data measured with the natural environment similar values, that is, the machine side basically there is no radiation leak. Staff into the machine again luggage detector entrance about 10cm, the value measured here is slightly higher for 0 .7 μSv/h to 0 .8 μSv/h, when the luggage sent out from the machine, will lead exit curtain top up, the detector displays the value immediately rose to 1μSv/h to 3μSv/h between.
