In hospital radiation protection engineering is widely used for X, Y ray protection requirements, radiation source and staff set effective shielding, reduce or eliminate the radiation of the ray.

Ray protection electric door:
The door is suitable for X machine room, CT room, deep treatment room, DSA room, machine room, gravel simulation machine room, ECT room, room 60, installed after the cobalt room and operation room medical radiation protection. The amount of lead protected by the gate structure is determined according to the radiation energy of the radioactive source.

Ray protection window:
High transparency, high lead content, stable performance.

One of the main effects of lead is effective radiation protection, so lead housing made of lead can be used to isolate harmful substances harmful to the human body, the main application and medical and chemical industry. Lead can also be used to manufacture a variety of lead containing alloys, as well as X ray shields, nuclear reactor equipment, etc.. To add to the radioactive operation protective equipment, the lead door can be directly used as external protection of the radiation source, such as the door of the X light room in the hospital is made of lead.

Construction method
1) and construction sequence:
(1) the total construction sequence: first ground, behind the wall, and then the ceiling, and pay attention to other processes, to avoid cross contamination, pay attention to the protection of finished products.
(2) clean up the project site after entering the construction schedule.
(3) start the surveying and stringing work.
(4) after the completion of the line, the ground construction, wall and ceiling construction began.

2) negative one layer computer room
This layer is only for the installation of protective doors.
