A Selenium source is formed by compressing the Se-74 (or Se-74 compound) into the desired shape and encasing it in an outer capsule. The Selenium 75 sources we offer are either cylindrical or spherical.
For a cylindrical source there are two dimensions quoted, 2x2mm for example refers to a source which is 2mm in diameter and 2mm in height. The dimensions of the source are always equal resulting in a source that is almost cubic in profile.
A spherical source has the Se-75 formed into a sphere. A spherical source is the best shape for radiography. The spherical Se-75 sources we offer give the highest activity for a given physical size resulting in high resolution and quick radiographs.
