Description

Key Advantages
High Sensitivity
Exceptional response to low-energy X-rays and gamma rays, enabling clear imaging with minimal radiation dose??critical for medical applications (e.g., pediatric CT) where reducing patient exposure is paramount.
Ultra-Low Afterglow (<0.01% @ 20 ms) Virtually no residual light emission after excitation, eliminating image artifacts in fast-scan applications. This is especially valuable for high-frame-rate systems like dynamic CT or real-time security scanners, where even minor afterglow can blur moving objects. Fast Conversion Speed With a decay time of 3 ??s, GOS ceramic processes radiation signals quickly, supporting high-throughput operations such as rapid cargo screening or multi-slice CT scanners. High Density (7.34 g/cm3) Excellent stopping power for X-rays and gamma rays, ensuring efficient absorption even in compact detector designs. This density makes it ideal for imaging thick materials (e.g., industrial components or dense tissues). Non-Hygroscopic Completely resistant to moisture, eliminating the need for protective coatings or hermetic sealing. This simplifies device design, reduces maintenance costs, and ensures stability in humid environments (e.g., clinical labs or outdoor industrial sites). Mechanical Durability (6.0 Mohs) Harder than many scintillation crystals (e.g., NaI, CsI), GOS ceramic resists scratches and impact damage??perfect for rugged applications like portable industrial detectors or high-vibration screening equipment. Technical Specifications Gadolinium oxysulfide (Gd?O?S) has a density of 7.34 g/cm3, a hardness of 6.0 Mohs, a refractive index of 2.2, an emission wavelength of 512 nm (green), a decay time of 3 ??s, an afterglow of <0.01% @ 20 ms, and no hygroscopicity.?
