Advanced Gauging currently has three “like new” Cesium (Cs-137) sources for sale. These sources, originally manufactured by Berthold Technologies, came into our possession as a result of our participation in the recent Sparrows Point source disposal project. All three sources are Berthold Model No. 7440-D-CR. They are only 7 years old and were originally purchased as spares and never actually put into use. In fact, they still have the manufacturer’s seal along with their original locks and keys (see photos below). Please note that your company must be specifically licensed to possess these sources before you can purchase them. Contact A.G.T. at 614-873-6691 or Sales@AdvGauging.com for details.
