Targeting Malnutrition: Isotopic Tools for Evaluating Nutrition Worldwide
Investigating Trace Elements

Why is IAEA measuring dietary intakes of trace elements?

The IAEA's role in dietary intake studies

The IAEA has been encouraging some nuclear laboratories in developing countries to establish collaborative research programmes with their national institutes of nutrition on projects that can take advantage of the high specificity and sensitivity of nuclear analytical techniques. Studies of trace elements in foods and diets have turned out to be among the most useful of these applications.

Nuclear and related analytical techniques (such as neutron activation analysis ICP-MS and XRF) provide high sensitivity and specificity for the determination of many of these elements infoodstuffs and diets. Examples of the IAEA's support for research on dietary intakes of trace elements include:
