What are the functions of radiation protection doors?
1、 Shielding effect
The radiation protection door contains radiation protection coating, which is primarily composed of barium sulfate. It is an important barium-containing mineral with excellent properties such as strong chemical inertness, good stability, resistance to acids and alkalis, high density, moderate hardness, and the ability to absorb harmful radiation. The exterior of the radiation protection door is made of stainless steel, typically measuring 21.50cm high x 130cm wide x 10cm thick. It includes a supporting frame and a 2-3mm shielding plate (the material and thickness requirements vary depending on the specific department and equipment), ensuring that personnel exposure doses meet national management standards.
2、Interlocking function between equipment
In the hospital's X-ray room, it is possible to establish a chain of advanced radiation shielding doors and X-ray equipment. When the X-ray equipment is activated, the radiation shielding door will automatically lock, ensuring that radiation cannot leak out of the room during X-ray exposure. Furthermore, the chain-linked radiation shielding door will enhance its protective strength according to the radiation intensity of the X-ray equipment, ensuring the safety of personnel outside the X-ray room.
3、Infrared sensing function
Currently, most radiation shielding doors on the market have infrared sensing functionality, specifically including automatic opening when a doctor or patient approaches the door, as well as automatic closing after a certain period of time. These functions in radiation shielding doors are achieved through infrared sensors that can detect human body heat.
4、Network automation features
Unlike regular doors used in residential settings, radiation shielding doors are typically more sophisticated and automated. Some radiation shielding doors are equipped with displays that provide real-time information on the door's status, including the type and intensity of radiation, and can even be remotely controlled from a computer. This allows X-ray room doctors to operate more efficiently, maximizing the utilization of medical resources.
Differences between radiation protection doors and ordinary doors
1、Different radiation shielding capabilities
A radiation-proof door is a specialized device designed for radiation shielding. Due to its superior shielding capabilities, it utilizes special materials that provide enhanced protection against radiation. Typically, a radiation-proof door consists of an outer layer of stainless steel and an inner layer of a radiation-shielding board, resulting in superior radiation shielding performance. Ordinary doors made of stainless steel or wood do not possess radiation shielding capabilities and are therefore unsuitable for use in environments with high levels of radiation.
2、Ease of operation differs
The radiation shielding doors available on the market can be controlled by computers, allowing consumers to easily open and close the doors using control buttons. This significantly reduces the time required to operate the doors, especially in hospital settings, thereby accelerating the delivery of medical radiation. In contrast, ordinary doors require manual operation, which can be time-consuming, particularly in areas with high patient traffic.
3、Different levels of safety
Hospitals can use medical radiation shielding doors that can be connected to the power supply of the irradiation device. When the door is open, the camera cannot be activated, and the irradiation device must be turned off before the door can be opened. This type of radiation shielding door can further prevent radiation leakage. Ordinary doors cannot be connected to the irradiation device, which may lead to the risk of forgetting to close the door, resulting in information leakage.
