What are the commonly used radioactive materials at Yale?

Yale University has a Broad Type License from the U.S. Nuclear Regulatory Commission (NRC). This allows researchers at Yale to use dozens of different radionuclides. However, the vast majority of the radioactive material used at Yale involves low-energy beta emitters used for biomedical research. These include H-3, C-14 and S-35. A high-energy beta emitter, P-32, is also commonly used. In addition, I-125 which has a complex decay scheme, is routinely used by many research groups at Yale.
