摘　　要： 利用VF-320型X射线荧光光谱仪(XRFS)对长兴电厂粉煤灰中有毒、有害微量元素及放射性元素含量进行了测试。结果表明,大部分微量元素及放射性元素都有在细粒径粉煤灰中富集的趋势。该电厂粉煤灰中有毒、有害元素的含量不高,只要施用量不超过8654kg/亩(129810kg/公顷),用作土壤改良剂或肥料,不会对农作物造成危害;若用于生产建材,只要将掺量控制在总量44%内,建材制品的放射性防护也是安全的。 In this paper, the contents of poisonous, deleterious and radioactive microelements of the fly ashes,which are drained from Changxing Power Plant, have been measured by X-ray Fluorescence Spectrometer. The results show that most of the microelements and radioactive elements have an enriching trend in fly ash with smaller particle. The contents of poisonous and deleterious microelement of the fly ashes are not high. When the fly ashes are used as soilimprover and fertilizer, they won＇t do any harm to the corn as long as the dosages don＇t exceed 129,810kg/hc（8654kg/ mu）. When they are used as raw materials for buildings, the radioactivity of the architectural products will be secure so long as the dosages don＇t exceed 44% of the gross materials.

关 键 词： 粉煤灰 微量元素 放射性 安全性评价
