A box of radioisotopes from Oak Ridge National Laboratory is visible on the counter. The U.S.D.A. commonly used radioactive material for a variety of research and testing, including the study of radioactive substances as fertilizer, as well as to model the impacts of radioactive material in soil and test the effectiveness of new insect control techniques or materials.
