Multielement analysis of foods and related materials by NAA
This paper presents FDA's use of prompt- and delayed-gamma thermal neutron activation analysis (PGAA and INAA, respectively), collectively referred to here is NAA, for the analysis of foods. Several elements of nutritional or toxicological importance can be simultaneously determined at levels ranging from trace to percent. Concentrations of aluminum, boron, bromine, calcium, chlorine, hydrogen, potassium, magnesium, manganese, nitrogen, sodium, and sulfur can be determined in < 1 day in most foods. For INAA, after a few weeks of decay following irradiation, cobalt, cesium, iron, rubidium, scandium, and zinc can also be determined. Other elements that are detectable in only some food types include cadmium, chromium, copper, iodine, phosphorus, antimony, selenium, titanium, and vanadium.
