Analysis of cadmium in food by multiple prompt γ-ray spectroscopy
چکیده انگلیسی

The Cd concentration in food is a public concern related to the human health. In order to remove Cd-polluted food, the development and validation of a rapid and sensitive method of Cd analysis is required. By applying the multiple γ-ray detection method to prompt γ-ray analysis (PGA), the influence from nuclei which emit only one prompt γ-ray at a time at every neutron capture reaction can be reduced, therefore the quantification limit of Cd is improved significantly. The limit of Cd contained in rice in the case of MPGA was evaluated, and under our proposed experimental conditions, it may be possible to quantify Cd content in rice to within 0.2 ppm in 10 min.
