Dr. Sun and his colleagues in Carolina published an article “A Study of the Organic and Nonorganic Food Ingredients with Instrumental Neutron Activation Analysis” in Radiation Science and Technology. The article indicates that INAA is a sensitive radioanalytical tool to tell the elemental information on atomic or nuclear levels, however, as a nuclear technique, INAA lacks the capability to probe the properties of compounds on the molecular level, which may be the real difference between organic and nonorganic food.
