A point source is a small cylindrical shaped capsule; about the size of a pen cap. The capsule contains an inner, even smaller capsule, where the radioactive material is sealed. For optimal protection, we also offer triple encapsulated sources, recommended for very corrosive environments.
Our custom rod sources have the radioactive material distributed across the entire source length as needed depending upon the application, vessel geometry, and detector. For continuous level measurements this improves the linearity of the counts per second change at the detector to change in level, when compared to standard point sources, ensuring the highest accuracy with the simplest calibration.
Our registered cast iron, steel, and stainless steel shields are filled with lead, tungsten, or both, offering the best shielding effect for every situation. Each shield is closeable, and is shipped locked shut until the device is put into operation.
