Abstract:
Neutron activation analysis (NAA) was applied to measurement of manganese (Mn) content in food as an example of ordinary hospital meals. The results showed that: 1. NAA permits measurement of Mn with a simple pretreatment procedure in comparison with AAS (atomic absorption analysis). 2. Daily Mn intake was estimated to be about 3 mg from food, and about 4 mg from green tea. Neutron activation analysis (NAA) has been used for measuring various elements under the conditions appropriate for the irradiated or radioactivated subject of analysis. We presently applied NAA to measurement of manganese (Mn) contents in food as an example of ordinary hospital meals with an estimation of daily Mn intake.
