Moving to landlocked Tennessee isn’t an obvious choice for most scientists with new doctorate degrees in coastal oceanography.
![Summer Widner, Stephanie Timbs, James Gaugler and James Avenell of ORNL are part of a team that processes thorium-228, a byproduct of actinium-227. As new uses for thorium are realized, particularly in medicine, the lab expects the demand for the radioisotope to grow.](/sites/default/files/styles/list_page_thumbnail/public/2021-08/Part%20of%20Th-228%20Team_1.jpg?h=09b6d1d3&itok=1_l1hx2l)
As a medical isotope, thorium-228 has a lot of potential — and Oak Ridge National Laboratory produces a lot.
