| The calculator provides information about a number of radionuclides commonly used in nuclear medicine: Cr-51, Co-57, Ga-67, In-111, Mo-99, Se-75, I-131, I-125, I-123, Tc-99m, Tl-201 and Xe-133. This information includes the decay constant, the half-life, and the energy and percent intensity of beta, gamma, and x-ray emissions. The calculator's main function is to provide the fraction of the nuclide activity that remains after specified periods of time have elapsed. |
