Caesium-137 (Cs-137) Sealed Sources for Instrument Calibration and Irradiation

High activity Cs-137 sources are used for dose rate measurement instrument calibration and small self-contained irradiators. Please see specific product pages for industrial, process control and oil well logging sources.

RAIMS can supply a wide variety of standard designs and activities from 10Ci (370 GBq) to approx. 2000Ci (75TBq). For high activity applications the Cs-137 is in the form of a pressed powder of Caesium Chloride blended to completely fill the capsule cavity. This is then encapsulated by autogenous TIG welding into a 316L stainless steel double encapsulation.

Complies with ISO2919
