Technical Characteristics and Safety Standards
-
Long-Term Stability: The FSG60 typically utilizes standard industrial isotopes like Cesium-137 (137Cs). Because of its long half-life (approximately 30 years), the source provides a reliable radiation signal for decades, minimizing the need for frequent source replacements.
-
Strict Safety Encapsulation: The source is enclosed in a specially constructed capsule that conforms to the highest international safety requirements. It typically meets classification C66646 according to ISO 2919, ensuring the capsule can withstand extreme pressure, temperature, impact, and vibration without leaking.
-
Defined Radiation Beam: When installed in a compatible source container, the FSG60 acts as a point source. The container shields radiation in all directions except for a specific, narrow window, providing a safe and effective measurement path.
-
Optimized Activity Selection: The FSG60 is available in a wide range of activity levels. This allows for precise dosage selection—strong enough to penetrate thick vessel walls or dense media, but low enough to ensure maximum safety for the surrounding environment.

Основные приложения
-
Continuous Level Measurement: Providing a steady radiation stream to a scintillation detector (like the FMG50) to track the level in tall silos or high-pressure reactors.
-
Density Measurement: Monitoring the concentration of liquids or slurries in pipes; the absorption of the gamma beam by the medium is directly proportional to its density.
-
Interface Measurement: Detecting the boundary between layers (e.g., oil and water) in large separators by measuring the change in radiation absorption.
-
Point Level Detection: Functioning as a high/low alarm switch in harsh environments where contact sensors cannot survive.
