A 25-year career with the U.S. Navy, commanding combat missions overseas, brought Tom Kollie back to where he came from — ready to serve his country in a new way.
![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.

A team of researchers at Oak Ridge National Laboratory and Purdue University has taken an important step toward this goal by harnessing the frequency, or color, of light. Such capabilities could contribute to more practical and large-scale quantum networks exponentially more powerful and secure than the classical networks we have today.
