Gamma sources

Sealed gamma sources are used in a range of activities (thickness gages, density testing, various industrial applications, etc.).

• Americium 241

Americium 241 sources are used for industrial calibration (thickness measurement, fill level measurement, etc.).
Americium 241 is sintered to form ceramic pellets enclosed in a single capsule made from stainless steel welded using the TIG process (window thickness 0.3 mm max.).

• Cesium 137

Cesium 137 sources are used for thickness, level and density measurement, as well as a range of other industrial calibration applications.
The source comprises cesium 137 in quasi-insoluble and anti-abrasive form. It is sintered to form a special ceramic material, and is therefore non-leachable. The ceramic sources are sealed inside stainless steel capsules (window thickness 0.4 mm to 0.8 mm).
The primary capsules are welded using the argonarc process, and enclosed inside a secondary capsule made from stainless steel and welded using the TIG process.

• Cobalt 60

Cobalt 60 sources are used for a range of industrial calibration applications.
A nickel-plated radioactive cobalt 60 cylinder is enclosed inside a double-walled capsule made from stainless steel and welded using the TIG process. The source is sealed inside steel capsules (window thickness 0.8 mm).
The primary capsules are welded using the argonarc process, and enclosed inside a stainless steel capsule welded using the TIG process.
