²¹⁰Po Emission Level in a Cement Plant

²¹⁰Po spontaneous deposited on silver foil. Using α spectrometer measured the specific activity of ²¹⁰Po in raw materials, additives, and cement production during the production technology process of the cement plant. The specific activity of ²¹⁰Po in raw material and additives varies from 5.42 to 901.59 Bq/kg. The specific activity of ²¹⁰Po in cement production is range from 22.71 to 124.74 Bq/kg. According to the input output balance, the maximum emission is 7.55×10¹⁰ Bq/a; the normalized emission is 5.67×10¹⁰ Bq/Mt.
