Activity concentration of 210Pb(210Po) in soils taken from cultivated lands

In this study, 210Pb(210Po) activity concentrations in surface soils taken from cultivated lands in the Buyuk Menderes Basin in Aegean Region, Turkey were determined. The 210Pb(210Po) activity in soil varies from 0.013 to 0.135 Bq/g with a mean value of 0.041Bq/g. Its distribution fitted close to normal curve. The mean annual effective dose equivalent was found to be 0.91μSv/y. The data obtained were statistically evaluated to explain the 210Pb(210Po) distribution in the cultivated lands. The effect of organic matter, clay, silt, sand contents and pH of the soil on the relative adsorption of the 210Pb(210Po) on the surface soils was also studied.
