X-ray film displays the radiographic image and consists of emulsion (single or double) of silver halide (silver bromide (AgBr) is most common) which when exposed to light, produces a silver ion (Ag+) and an electron. The electrons get attached to the sensitivity specks and attract the silver ion.
X-ray films for general radiography consist of an emulsion-gelatin containing radiation sensitive silver halide crystals, such as silver bromide or silver chloride, and a flexible, transparent, blue-tinted base. The emulsion is different from those used in other types of photography films to account for the distinct characteristics of gamma rays and x-rays, but X-ray films are sensitive to light.
The global X-ray film market is expected to register a CAGR of 5% over the forecast period of 2018–2023. In the medical industry, the usage of X-ray films in dental inspection, mammograms, and orthopedic inspection hold the major share in the market. The industrial sector has a long established usage of X-ray films and is widely used in NDT methods for volumetric examination radiography.
The presence of X-ray machines in hospitals enables physicians in detection of somatic issues, as well as trauma. X-ray is very useful for detection and treatment of neurological problems, cancer, cardiac diseases and bone related problems. The existing pervasiveness of these issues will increase demand for the product over the forecast period.
