We are proud to announce that the Nucleus is now producing competitively priced calibrated sources are housed in arclylic plastic disks and are exempt from licensing.

In addition to the calibrated single istope sources we are now offering two multi gamma standards—the multi gamma Standard 1 (MGS-2). The MGS-1 consists of a mixture of three Europium radionuclides: Eu-152, Eu-154, Eu-155. These long lived sources are intended for determining photopeak efficiency as a function of energy in Germanium detectors. The MGS-2 is a mixed Standard source consisting of four radionuclides: Mn-54, Co-60, Sb-125 and Eu-155. This source also used for determining photopeak efficiency can be used beter for detectors with lesser resolution.

We also are taking some special orders to meet your specific needs in radionuclides. You can count on us for the most competitive prices and the highest quality in radionuclides.
