Description
Technical field
The present invention relates to x-ray protection technical field, and in particular to a kind of transparent radioprotective of X-ray safety check equipment
Cover.
Background technology
Mainly there is scattering according to light and repeatedly interference in the present invention in the photonic crystal that aperiodic materials are constituted, form light
Sub- forbidden band.In forbidden band, after dielectric function scattering, the x-ray intensity of some wave bands can refer to x-ray because destruction interference is presented
Number decay, it is impossible to transmit in system.Play the protection effect of X-ray.The X-ray safety inspection that public place occurs at present sets
Standby radiation shield is entirely metal quality, the protective equipment of transparent material does not occur.Luggage be can't see in safety check cabin
Topple over, the situation of heap card.And easily exit it is crowded, rob and take, wrong take luggage.The normal average annual x-ray radiation amount of working clan with
The maximum data can reach about 0.007mSv as the standard of calculating, the effective dose for receiving radiation, in addition the lead curtain of monolayer
The radiation when being pulled up increases sharply, and can cause the healthy hidden danger of passenger.
The content of the invention
The present invention is solution above-mentioned technical problem, there is provided the transparent radiation shield of X-ray safety check equipment, realizes transparent
Rays safety detection apparatus, the purpose of invention are exactly the shortcoming for making up existing equipment, more effectively protect the normal health peaces for crossing safety check passenger of Jing
Entirely.
To realize above-mentioned technical purpose, the technical solution adopted in the present invention is：X-ray safety check equipment it is transparent
Radiation shield, is provided with metal framework, is provided with side cover plate in the both sides of metal framework, is provided with upper cover plate at the top of which, side cover plate with
Upper cover plate constitutes cargo channel to be checked, and a plurality of seamlessly radiation shield bar is linked with cargo channel to be checked, described
Upper cover plate is made up of the crystal film with photon that clear glass and plating are located on clear glass, and crystal film with photon is by 5 layers of zinc sulfide and 5
Layer Afluon (Asta) alternates superposition composition type composite construction, and the composition of wherein medium A, C media, E media, H media and M media is equal
It is identical, it is zinc sulfide, the composition all same of medium B, D media, F media, L media and N media is Afluon (Asta), the thickness of medium A
For 2.69nm, the thickness of medium B is 5.07nm, and the thickness of C media is 1.92nm, and the thickness of D media is 3.62nm, E media
Thickness is 1.153nm, and the thickness of F media is 2.17nm, and the thickness of H media is 0.865nm, and the thickness of L media is 1.63nm, M
The thickness of medium is 0.67nm, and the thickness of N media is 1.26nm, and medium A laminating clear glass is arranged.
The invention has the beneficial effects as follows：The x-ray non-browning glass for being coated with crystal film with photon adopted at top can reach anti-
Radiation and the visual effect of luggage, it is to avoid luggage is toppled in safety check cabin, heap card and passenger luggage exit it is crowded,
Rob take, the wrong puzzlement for taking luggage；Both sides adopt incrassation type stereotype, seamless spliced double curtains in addition（Seamless spliced lead curtain is adopted
It is double-deck）Structure, the healthy hidden danger of the passenger for having prevented to greatest extent to be frequently necessary to safety check；The luggage carousel length of increase
Luggage can be avoided in exit congestion.In addition the dielectric material of composition photonic crystal is more economical, and cost performance is higher,
The feature of environmental protection also increases.
