Determination of aluminium concentration in food samples is important for the food safety and quality control purpose owing to its toxicity. This work demonstrates determination of aluminum concentrations in raw rice samples, obtained from agricultural field, by instrumental neutron activation analysis (INAA) using reactor neutrons and high resolution gamma-ray spectrometry. Particle induced gamma-ray emission (PIGE) method was also standardized for the determination of aluminium content in some samples. The aluminium contents were found to be in the range of 5–80 mg kg−1. INAA and PIGE methods were validated by analyzing five reference materials obtained from NIST and IAEA.
