Scientists who will become part of the NML complement, as employees, undergo a very rigorous security screening process. Depending on their particular line of work, they will require not only a security clearance protocol but also very in-depth training that is appropriate to their level of work.
In addition, scientists are sometimes called to work with other institutions or in collaboration, at which point a number of different mechanisms are in place, including the development of collaborative research agreements, or other forms of collaborative research frameworks that are appropriate for the work at hand.
