See Technical Information section.

Only typical sources are listed; inquiries are invited for alternative capsule designs and activities.

For Low Energy X-ray applications, these sources offer a radionuclide with X-ray emissions around 6keV. Beryllium window capsules are normally used to enhance the low energy emmissions. The activity is contained in a stable, homogeneous active element.
