Radioactive Sources


Precisely manufactured radiation sources for a variety of emissions.

  • Safe to use
  • Easy disposal
The solid sources we supply are securely encapsulated in heat-resistant, waterproof plastic disks 25mm in diameter and 4–6mm thick. The sample is deposited in a well that is then filled with an epoxy material, safely sealing in the radioactivity.

Note: Model PO-210S Polonium-210 is an unsealed disk source.
