The production of dicalcium phosphate are included in the list of industries classified as NORM in Euratom 29/96. The aim of this study is to determine the con-centrations of specific flows and their variability over time of 226Ra, 210Pb and 210Po in the inputs and out-puts of the production process. Also classified areas of the plant and the workers according to the radio-logical risk and radiation protection measures have been proposed. The results show that the rock phos-phate has a high specific activity of the 226Rn, 210Po and 210Pb in secular equilibrium (1500-2000 Bq • kg-1) but the outputs of the process will distort the secu-lar equilibrium. The only shortfall is the flow balance of 226Ra, which accumulates in the process. The dis-...
