Vertical distribution of 226Ra and radiological hazards indices of soil samples

Vertical distribution of 226Ra and radiological hazards indices of soil samples

The vertical distribution of 226 Ra was investigated in soils from the cultivated and undisturbed areas in Rudovci, municipality Lazarevac, Serbia. There were three profiles, each profile divided on four horizons, what gives 12 soil samples. The specific activity of 226 Ra in soil and sediment sampl...

Zusammenfassung:The vertical distribution of 226 Ra was investigated in soils from the cultivated and undisturbed areas in Rudovci, municipality Lazarevac, Serbia. There were three profiles, each profile divided on four horizons, what gives 12 soil samples. The specific activity of 226 Ra in soil and sediment samples was determined by using the gamma-spectrometric method. Analysis of the vertical soil profiles indicated that the activity of 226 Ra was not extremely changed with depth. To evaluate the radiological hazards of 226 Ra in the samples, the absorbed dose rate, the annual effective dose rate, the radium equivalent activity, and the external hazards index were calculated according to the UNSCEAR 2000 report.
