Source Holder/Radiation Source
The Ronan Mold Level System utilizes either Cs-137 isotope or Co-60 as its source of radiation. The cesium isotope is often selected for its excellent penetration capability and 30 year half-life. The source material is doubly encapsulated in a heliarc-welded stainless steel capsule and placed into the stainless steel source rod. The source rod is contained within a lead filled iron source holder, which provides shielding in all directions except where radiation is beamed toward the detector. A shutter can be provided to allow complete shielding during shipping, installation and maintenance.
