The Unidirectional transparent layer includes Unidirectional transparent film, silver-plated or pad pasting Unidirectional transparent glass.
Another goal of the invention of the present invention be to provide it is a kind of be used to distinguish the method whether film exposes, using above-mentioned dark
It is packed to cut out film to be detected；Before being exposed to film, have in the dark state in Unidirectional transparent layer first on observation camera bag
No visible ray, such as find that there is visible ray the phosphor layers inside Unidirectional transparent layer, then show that the film in the camera bag has exposed；
Such as without visible ray, then show that the film in the camera bag is unexposed.
Further, the firing time of phosphor layers 3-900 seconds, 0.5-15 hours sunset glow time.
Further, the light transmittance of the transparent surface of the Unidirectional transparent layer is the printing opacity of the impermeable smooth surface of another side more than 70%
Rate is 0%.
It is 0% that Unidirectional transparent layer choosing, which selects its side light transmittance, in the present invention, and opposite side light transmittance is then saturating at its more than 70%
The one side that light rate is more than 70% coats 1-2 grams of phosphorus formation phosphor layers, then is coated with adhesive tape phosphorescence thing
The Unidirectional transparent layer of matter layer is pasted and fixed on the outside of camera bag body not influence the position of film image, makes Unidirectional transparent layer
Impermeable smooth surface is exposed to the open air in outside air, it is to avoid phosphorus absorbs the visible ray in environment.
Due to phosphorus electronics after high-energy radiation is absorbed by ground state transition to excitation state, and in follow-up one section
Between gradually de excitation, and discharge during de excitation visible ray.In ray detection work, operating personnel are to equipped with the dark of film
Bag using X-ray or gamma-rays start exposure, now the phosphorus on camera bag start absorb high-energy ray, its internal electron by
Ground state transition is to excitation state；After end exposure, the electronics de excitation of excitation state is fallen after rise, and visible ray is constantly discharged in the process.
If it is used which operating personnel, which distinguish, follow-up work is directly carried out, if staff is to some dark
Whether bag had used and had thrown doubt upon, or different teams and groups personnel are when taking film mutually and not can determine that, only need to be in dark
Under state（Expose an aperture in more black place or direct covered with hand）Whether observation phosphorus releases visible ray
Easily distinguish whether the camera bag exposes, so that the occurrence of effectively preventing " twins ", saves film and time.
Different phosphoruses have it is different stress time and de excitation time, can be according to the frequency of use of camera bag, conventional
Time for exposure choose different phosphoruses, with ensure its in next time using preceding de excitation completely so that reach avoid it is same
Film multiexposure, multiple exposure and the purpose that can be reused in lower task.Such as when camera bag needs to reuse in a short time,
The phosphorus used is including but not limited to II-VI race using zinc sulphide as representative quick-acting phosphor powders, its firing time 3- in short-term
15 seconds, 0.5-1 hours sunset glow time；When camera bag has longer use interval and time for exposure, the phosphorus used can be with
It is the aluminate for being doped with rare earth element, its firing time 3-15 minutes, 6-15 hours sunset glow time.
The present invention makes simple, and a camera bag body only needs to 1-2 grams of phosphorus, and its is with low cost, is worthy to be popularized.Separately
Outside, the camera bag may be reused.
