GREEN SENSITIVE FILM (Wet X-ray Film)
Green Sensitive Film
Premium Green Sensitive Film is orthochromatic wet-process medical X-ray film widely adopted in radiology departments for high-precision clinical diagnosis. Adopting optimized fine grain imaging technology, this green-base radiographic film targets chest, abdomen and esophagus examinations. It effectively lowers required radiation exposure while retaining complete anatomical details, delivering stable, clear black-and-white images after standard chemical wet development.
Core Performance Features of Green Sensitive Film
Different from blue sensitive X-ray film, this green sensitive film features ultra-high photosensitivity that helps reduce radiation dose for patients without sacrificing image definition. The double-sided fine-grain emulsion paired with integrated anti-static coating eliminates static dust spots during film transport, cutting defective negatives in batch processing. It presents distinct separation between light and dark image areas with balanced high contrast, making soft tissue and organ boundaries easy to distinguish for radiologists.
The film boasts powerful development adaptability, supporting multiple processing workflows including super-rapid 45-second high-speed machine development, standard 90s fast processing, low-volume small machine operation and traditional room-temperature manual development, fully matching diverse hospital darkroom equipment configurations.

Storage, Darkroom & Processing Rules
All unexposed green sensitive film must be kept in cool, dry, fully dark storage space with temperature 10°C–23°C and relative humidity 40%–60%. Keep away from direct sunlight, high heat, moisture, heavy pressure, corrosive gas and penetrating radiation such as X-ray and gamma ray. Unopened cartons shall be placed vertically to prevent emulsion layer adhesion caused by long-term flat compression.
This wet radiographic film matches all mainstream developing and fixing chemicals on the market. It supports two common processing temperature ranges: 35°C–38°C high-temperature automatic machine development and 20°C–25°C room-temperature manual tank processing. Always prepare liquid agents according to standard dilution ratios and use within the valid shelf life to guarantee consistent imaging quality.
Darkroom safelight standard: Adopt 15W frosted bulb equipped with deep red filter, maintain a minimum distance of 1.2 meters between light source and film stock to avoid premature fogging on unexposed emulsion.
Matching System Compatibility
This green sensitive film perfectly cooperates with green-type X-ray intensifying screens to boost exposure efficiency and image uniformity. It works steadily for daily diagnosis in large general hospitals and small independent clinics, with built-in anti-static coating effectively reducing surface dust adhesion and static artifact issues during mass film output.
Frequently Asked Questions
Q1: What clinical examinations is green sensitive film mainly used for?
A: It is the primary film for chest, abdomen and esophagus radiographic imaging, and also applicable to routine skull and extremity skeletal radiography scenarios.
Q2: What core strengths does green sensitive film own?
A: It features high photosensitivity to lower patient radiation dosage, high contrast for clear tissue differentiation, and excellent anti-static performance to eliminate static-related image defects while maintaining stable fine-grain imaging quality.
Q3: How to select suitable processing chemicals for this film?
A: It is compatible with universal standard X-ray developer & fixer sold on the market. Prepare solutions following official dilution standards and finish usage before reagent expiration to obtain optimal radiographic results.
