Purpose of the development: Designed for radiography.

Recommended application field: Development can be realized in the industrial ministries, which requires quality control of welded joints and non-destructive testing of industrial products, as well as in medical radiology at diseases where it is impossible to use intensifying screens (for example, in dentistry).

Technical characteristic: Main technical characteristics: - Sensitivity to X-rays X-rays 25-30 [-1]; - The density of silver in the 0 - 8,0g / sq.m .; - Flaw detection sensitivity at the level of classical AgHal materials with microcrystals of the same size class.

Advantages over analogues: As without crane detector radiography proposed photographic material has no analogues in the world. In comparison to the well known film of D-7, which produces a firm Agfa, with a capacity of silver and 20 g / sq.m., Our emulsions when applied to a flexible substrate with a density of 7.0 g / m. has the same characteristic curve for the optical density D = 4,0. Furthermore, due to the specificity of technology of heterophase microcrystals of photographic materials based on them better with time retain their sensitometric parameters. Characteristics of the material make it competitive on the world market for photographic X-ray detection.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: The economic attractiveness of composite systems is that the production of such photographs is achieved considerable savings of precious metals (silver) without degrading the sensitometric parameters of photosensitive layers. Minor complications technology of heterophase systems compensated significantly (up to 3 times) savings silver.

Description of the development:
()
The proposed material, sensitive to X-rays, which is received on the basis of the type of heterophase microcrystals without X-ray luminescent silver core - photosensitive silver halide shell which, when given the manifestation of highly dispersed silver which has greater opacity. This makes it possible to significantly reduce the capacity of silver information capacity without deteriorating the image and combine within a single microcrystal intensifying screen and a photosensitive phase.
