Investigation on Natural Radioactivity Level of Fly Ash in Xian DaTang Thermoelectricity Group

摘要：

In order to have a comprehensive understanding of the application and radioactivity level of fly ash in Xi an DaTang thermoelectricity group,five samples were collected from fly ash stack of the group by quincunx collecting method.Natural radioactivity nuclide contents in the samples were measured by a low background anti-Compton HPGe Gamma spectrometer.The result was that the contents of 238 U 、226 Ra 、232 Th 、40 K respectively were 67.6Bq/kg 、 79.5Bq/kg 、72.7Bq/kg 、190Bq/kg.According to national standard GB6566-2001,the result indicates the radioactivity level of all the samples is at the common background level and the fly ash can be used as the A kind building materials. Finally,the future application of the fly ash in Xi an DaTang thermoelectricity group was analyzed.
