Description
Technical field
The present invention relates to medical accelerators room hole radiation protection technique through walls fields, more particularly to a kind of accelerator room
Pipeline through-wall hole factors for radiation shielding device and accelerator room.
Background technique
Accelerator room exterior wall is very thick, and usual concrete exterior wall thickness reaches 1 meter or so；Fan is additionally used in treatment chamber inlet
Road design；The door of therapeutic room also uses 1 meter thick of composite protection door.The main purpose of these designs is provided to prevent spoke
Ray it is excessive.And power supply and air-conditioning are needed in accelerator room, so exterior wall has pipeline through-wall hole hole, domestic existing doctor
Radiation Shielding Re design is not all done at the general hole of the accelerator room of institute, is blocked since pipeline is also bad too much, so so
The enclosed structure shielding gone all out to fight the floods, it is complete to be destroyed because of the exposed of hole through walls, do so thick exterior wall and external door
Also the requirement of shielding protection all is not achieved without meaning.
Again since accelerator room is typically all to be located next to therapeutic room's exterior wall and doorway, the waiting area of patient is typically also
Herein, the medical worker and medical patient for long-term work herein, can have an adverse effect to health.
External this way uses physics radiation protection form, and hole through walls is also made into the form in the road Zi Wanmi " ", this
The characteristic that sample can only be taken the air line due to ray, the curved wall of " " word by two sides carry out shielding protection radiation.But this shielding
Protection design idealizes very much, since this road " " Zi Wanmi requires pipeline is formed by connecting by two elbows, if wall
It is made into this form, two elbows at all just do not enter by installation.Because we think about it Tetris, this game is just understood
, this pipeline can not make, unless pipe prefabrication is entered when wall does not pour.It can domestic construction at this stage
Ability be not achieved it is so accurately prefabricated, and if this pipeline be broken or leak.So it is prefabricated enter just change at all
Not.Still another shortcoming is that the elbow-making of pipeline has specification, it is the pipe diameter for needing 1.5 times, if I
For 320 thick pipelines, then doing the curved furred ceiling headroom that requires of so a word is at least 0.32x1.5x2+0.32=
1.28 meters of space, even if being at least also required to 0.32x2=0.64 meters of furred ceiling headroom using air hose header, the waste of institute's ether is built
Height is built, common building storey height can not meet, and domestic project is also impossible to that word is curved in order to do this increases 1 layer height
Rice.
