Title: Radioactive contamination in Croatia by phosphate fertilizer production

Abstract:
The contents of natural radionuclides (radium, uranium and potassium) were measured in the area of a phosphate fertilizer factory in central Croatia, as a part of extended and still ongoing monitoring program of radioactive contamination of human environment in Croatia that is performed by the Radiation Protection Unit of the Institute for Medical Research and Occupational Health in Zagreb. Activity concentrations in all analyzed media (waste water, trickling water from piezometers, phosphogypsum deposit and final products) considerably fluctuated, especially in phosphogypsum and wastewater. Mean 226Ra activity concentration in waste phosphogypsum was measured to be 483 ± ; ; ; ; 190 Bq/kg. Based on that value, it was estimated that 4 million cubic meters of phosphogypsum that have been deposited up to now contain about 4.3 10E12 Bq, i.e. about 200 g of 226Ra. However, effective dose for an adult that would be incurred by consumption of water from nearby wells was estimated to be 5.3 ± ; ; ; ; 1.3 µ ; ; ; ; Sv. The results show that 226Ra activities cause effective doses, which are below the recommended maximum as the estimated annual 226Ra effective dose does not exceed 0.1 mSv as recommended by the World Health Organization.
