X-Ray Film

X-ray films are an essential component in traditional medical and industrial radiography. First developed after Wilhelm Conrad Röntgen’s discovery of X-rays in 1895, these films have evolved from glass photographic plates to advanced polyester-based films introduced by George Eastman in 1918. They remain widely used today for diagnostic imaging and industrial applications.

Features & Specifications:

• Base: Transparent polyester support (~0.25 mm thick)

• Emulsion: Contains light-sensitive silver halide crystals (mainly silver bromide) in a gelatin matrix to capture the latent image

• Protective Layer: Thin gelatin coat to prevent scratches or damage

• Substratum: Adhesive layer binding the emulsion to the base

• Film Sensitivity (Speed): Available in different speeds for reduced exposure and enhanced patient safety

• Types:

  • Screen Type Film: For use with intensifying screens

  • Direct Exposure Type Film: Used in dental and other direct applications

• Emulsion Coating:

  • Double Emulsion: Higher sensitivity, faster image capture

  • Single Emulsion: Greater detail, higher image resolution

Applications:

• Medical Radiography: General diagnostics, dental imaging, and specialized radiographic studies

• Industrial Radiography: Non-destructive testing (NDT), weld inspection, material testing
