The Medical X-ray film reveals the radiographic image which consists of the most typical (single or double) silver halide emulsion that creates a silver ion and an electron when exposed to light. The electrons are bound to the specks of susceptibility which trap the silver ion. To resist physical pressures, such as heat, creasing, buckling, friction, etc., Hospital medical X-ray film should always be treated carefully. Whenever medical x-ray films are filled and external clamping systems are used in semi-flexible holders, care should be taken to ensure that the pressure is uniform. The strain can be big enough to create desensitized areas in the radiograph if a medical x-ray film accessory bears on a few high points, such as on an un-ground weld.
