Why do hospitals use security screening machines? Does the X-ray security inspection machine pose a health hazard to the human body?
1, The importance of hospital security screening machines
A hospital is a special public place with a large number of patients, family members, and medical staff coming and going every day. The installation of hospital security screening machines is of irreplaceable importance. Firstly, it can prevent patients or their families from carrying dangerous items (such as knives and other items that may cause violent injury) into the hospital, ensuring the personal safety of medical staff. Medical staff may encounter various complex situations during the treatment of patients, and with security screening machines, potential safety threats can be reduced. Secondly, it can prevent unauthorized medical equipment or drugs from entering the hospital, ensuring the medical order and drug management safety of the hospital.
2, Types and characteristics of security screening machines
Hospital security screening machines usually use low radiation channel security screening machines. Considering the large number of patients in the hospital, including pregnant women, children, and frail patients, low radiation screening machines can minimize the impact on their health to the greatest extent possible. Its channel size is moderate and can meet the security needs of patients and their families carrying handbags, small medical supplies boxes, and other items. The image display of the security check machine is clear and can accurately identify the differences between medical devices, drugs, and other dangerous goods, making it easy for security personnel to make judgments.
3, Is there a safety hazard to the human body caused by radiation during security checks
(1) The impact of single radiation is minimal, but the principle of protection is not to accept ionizing radiation unless necessary. According to China's "Classification of Radiation Devices", X-ray human security equipment belongs to the category of "other X-ray machines above the exemption level" and is classified as Class III radiation devices. According to the General Technical Requirements for Micro dose Transmitting X-ray Human Safety Inspection Equipment, the single inspection dose of human safety inspection equipment should be less than or equal to 4 μ Gy.
(2) It is reported that the Third People's Hospital of Henan Province uses the Auspicious AS-5030 security screening machine. The relevant person in charge of the Ministry of Environmental Protection stated that the preliminary monitoring results of the radiation environment monitoring department on a certain model of the brand's human body security screening device show that, based on a single examination time of 4 seconds for the examinee, the radiation dose is less than 0.77 micro sieverts (μ Sv). If tested 12 times within a year, the effective dose for the public reaches 10 microsieverts.
(3) According to radiation experts, the 10 microsecond level is a reference value for the management of annual effective dose exemptions for the public. Therefore, it is preliminarily judged that a single inspection of this type of equipment has little impact on individual radiation. However, Professor Wang Zuoyuan from the Institute of Radiation Protection and Nuclear Safety Medicine at the Chinese Center for Disease Control and Prevention stated that radiation is divided into two types: ionizing radiation and non ionizing radiation. "Both radio waves and visible light in life will bring non ionizing radiation, while X-rays belong to ionizing radiation. After the human body is exposed to X-rays, it will cause an increase in the incidence rate of cancer. Its protection principle is that it is unnecessary to accept ionizing radiation."
The hospital security check machine is closely integrated with the overall security system of the hospital. It works in conjunction with the hospital's security and fire safety systems. For example, when the security check machine detects flammable materials, it should promptly notify the fire safety department; If any items that may pose a threat to hospital security are found, measures should be taken in conjunction with the security department. Moreover, security check data should be integrated with the hospital's information management system to provide data support for the hospital's safety management and decision-making.
