Instrumental neutron activation analysis has been utilized for the quantification of 24 major, minor and trace elements in dried apricots (Prunus armeniaca), dates (Phoenix dectylifera), figs (Ficus carica) and raisins (Vitis vinifera) using a low-power reactor as the neutron source. The weekly intakes of aluminium, arsenic, boron, calcium, chlorine, cobalt, chromium, iron, mercury, potassium, sodium, magnesium, manganese, molybdenum, antimony, selenium and zinc have been calculated and compared with the Recommended Dietary Allowance/Estimated Safe and Adequate Dietary Intake values through consumption of 100 g dried fruit. Fairly adequate levels of calcium, cobalt, iron, potassium and magnesium were determined in these dried fruits while the contribution of chlorine, chromium, molybdenum and sodium to the Recommended Dietary Allowance was found to be insignificant. Apricot is a nutritionally rich source of potassium, magnesium and cobalt, while chlorine and manganese contents were found to be highest in dates. Figs are an ample source of calcium, iron, magnesium and manganese, whereas raisins provide the highest intake of chromium, molybdenum and sodium. The toxic element contents of these dry fruits are considerably below the tolerance limits.
仪器中子活化分析已被用于定量分析干杏（Prunus armeniaca）、枣（Phoenix dectylifera）、无花果（Ficus carica）和葡萄干（Vitis vinifera）中的 24 种主要、次要和痕量元素，使用低功率反应堆作为中子源。通过食用 100 克干水果，计算了每周铝、砷、硼、钙、氯、钴、铬、铁、汞、钾、钠、镁、锰、钼、锑、硒和锌的摄入量，并与推荐的膳食允许量/估计安全和充足的膳食摄入量值进行了比较。在这些干水果中，钙、钴、铁、钾和镁的含量相当充足，而氯、铬、钼和钠对推荐的膳食允许量的贡献可以忽略不计。杏是钾、镁和钴的营养丰富来源，而氯和锰的含量在枣中最高。无花果是钙、铁、镁和锰的丰富来源，而葡萄干提供最高的铬、钼和钠摄入量。这些干水果的有毒元素含量大大低于耐受限度。
