Radioactive Materials

The use of radiation in a university, where a large number of people may be unaware of their exposure to radiation hazards, makes strict adherence to procedures established by federal and state authorities of paramount importance.

RadMat Training

Prior to working with, handling, and storing radioactive materials, the RadMat Handler training must be completed.

Radionuclides

Research is normally performed using a select number of radioactive isotopes. Generally, these isotopes are short lived, meaning they will decay to stable daughter products within a reasonable length of time, and are beta emitters. However, there are exceptions to both of these general statements.
