BLUE SENSITIVE FILM (Wet X-ray Film)
Blue Sensitive Film
Blue Sensitive Film is a high-performance wet-process medical X-ray film widely used in routine hospital radiology departments. Adopting professional blue-sensitive photosensitive technology with a 420nm spectral absorption peak, this medical X-ray film relies on silver bromide crystal photoelectric reaction to form precise black-and-white images after chemical development. Optimized for bone and thoracic imaging, blue sensitive film delivers cleaner background, faster exposure response and more natural grayscale layering, making it the preferred consumable for daily general radiological examinations.
Product Advantages & Imaging Characteristics
Different from green-sensitive X-ray films, blue sensitive film features lower base fog level, higher photosensitive speed and more balanced contrast performance. It effectively reduces image background noise while shortening exposure time, greatly improving daily examination efficiency. The film clearly presents fine bone trabeculae, soft tissue boundaries and internal thoracic structural details, supporting accurate judgment for routine skeletal and torso radiography.
Constructed with premium blue PET base and double-sided uniform photosensitive emulsion coating with anti-fog protection layer, the film maintains stable imaging consistency in long-term batch use. It features strong development compatibility, adapting to both manual room-temperature processing and high-speed automatic machine development, fully matching mainstream hospital darkroom workflows.

Storage & Processing Guidelines
Blue sensitive film must be stored in a cool, dry, dark environment with temperature controlled at 10°C–23°C and humidity between 40%–60%. Keep away from direct sunlight, high temperature, moisture, dust, harmful volatile gases and penetrating rays such as X-ray and gamma-ray to avoid pre-exposure and performance attenuation. Unopened film packages need vertical storage to prevent emulsion extrusion adhesion and ensure flatness.
This wet X-ray film supports dual processing modes, compatible with all mainstream medical developing and fixing agents. Standard proportional preparation and in-expiry developer usage can ensure stable low-fog and high-contrast imaging results for daily radiology diagnosis.
Frequently Asked Questions
Q1: What clinical scenarios is blue sensitive film suitable for?
A: It is mainly applied for routine X-ray imaging of human bones, limbs, skull and thoracic cavity. With ultra-low fog level and balanced contrast, it clearly displays bone trabeculae and internal thoracic fine structures, perfectly matching daily general radiology examination needs.
Q2: What advantages does blue sensitive film have over green sensitive film?
A: Compared with green-sensitive film, blue sensitive film features lower base fog, faster light sensitivity and more natural balanced contrast. It is more suitable for fast shooting and high-definition bone structure display, delivering cleaner imaging quality for routine radiology work.
Q3: What development methods are supported for this wet X-ray film?
A: It supports both normal-temperature manual development (20°C–25°C) and high-temperature automatic machine development (35°C–38°C). With strong reagent compatibility, it adapts to all mainstream darkroom processing environments.
Q4: What are the darkroom safelight operation requirements?
A: Use a 15W frosted bulb with deep red filter, placed at least 1.2 meters away from the film. Avoid prolonged or close light exposure to prevent fogging defects and ensure stable original film performance.
