摘要：

Gross alpha and gross beta activities were determined for mineral samples collected from five amang tailing factories. The measured activity of alpha ranged from 31 to 220,000 Bq kg(-1) with an average 9,154 Bq kg(-1), whereas for beta activity ranged from 9 to 552,000 Bq kg(-1) with an average 19,811 Bq kg(-1). The higher gross alpha and gross beta observed of monazite while the lowest recorded of waste (sand) and pyrite for gross alpha and gross beta activity respectively. The minimum detectable activities were 180 and 40 Bq kg(-1) for gross alpha and gross beta respectively.
