Abstract
The invention relates to a protection door structure of radiation-retarding shield room. Said invention includes protection door and square shielding columns connected with exit position of enclosure wall of said shield room. Said invention also provides the connection structure of said protection door and square shielding columns, said structure can effectively prevent the ray in the shield room from directly leaking toward exterior, and can raise service life of said protection door.
Description
Technical field
The present invention relates to the radiation protection technique field, especially between radiation-resistant labyrinth type shielding.
Background technology
At nuclear technology field, radioactive source or x-ray apparatus be at research, debugging and production period, is called between shielding for protection operating personnel and the public avoid the special factory building that the radiation infringement builds.In the prior art, as shown in Figure 1, generally all be to constitute between shielding by rectangle enclosure wall and protective door and labyrinth wall.In the actual construction between shielding because the influence of civil engineering deviation, generally all have between protective door and the barrier shield bigger slit (＞3cm).Cause the room inner rays to see through the safety zone of this clearance leakage beyond between shielding like this, thereby cause the dose of radiation level of regional area obviously to increase, to healthy and safe formation harm the personnel of this stop.In order to reduce the slit of body of wall between protective door and shielding, common way is that the artificial fitting allowance with enclosure wall between protective door and shielding is adjusted into negative common difference in the application.But in actual moving process, enclosure wall collision mutually, violent friction shorten dramatically the application life of protective door between the protective door of this structure and shielding.
Goal of the invention
At above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of protective door structure that is used between radiation-resistant glass.It can overlap enclosure wall between protective door and shielding dexterously, and ray interior between preventing from effectively to shield improves the application life of protective door simultaneously directly to external leakage.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes with following dual mode.
Compare with prior art, the present invention has carried out simple transformation to the structure of enclosure wall between protective door and shielding, the slit of ray between can preventing from effectively to shield by door and wall prevented the pollution of ray to surrounding environment and personnel to external leakage, ensured safety.The occupation of land space has been saved in labyrinth design in saving between former shielding simultaneously greatly.Consider the installation deviation of the manufacture deviation and the protective door of civil engineering deviation, protective door, even have the slit between protective door end and the square shielding post, ray is the slit in labyrinth through shape, must take place to arrive outside the protective door after the repeatedly scattering, to be weakened greatly through the ray that repeatedly scatters out, can be reduced by 10

4Doubly.In use avoid the sharp wear between enclosure wall between protective door and shielding in addition, improved protective door application life.
The present invention is further illustrated below in conjunction with accompanying drawing and concrete embodiment.

Fig. 1 is for overlooking the cross section structure schematic diagram between prior art shielding;
Fig. 2 is for overlooking the cross section structure schematic diagram between the shielding of one embodiment of the present invention;
Fig. 3 is for overlooking the cross section structure schematic diagram between the shielding of another embodiment of the present invention.
The specific embodiment
The present invention has in use solved well and has certain slit between the enclosure wall between protective door and shielding and bring between shielding inner rays directly to leak easily, causes the environmental radiation pollution problems.Experiment showed, that the ray through repeatedly scattering out will be weakened greatly, can reduce by 10
2～10
4Times, thereby the health and safety of effective support personnel and environment.
