Abstract
The distribution and origin of natural 40K,226Ra and228Ra and artificial 137Cs have been investigated in the surface soil of a West Macedonia basin at four lignite fired power plants. No significant increase in specific activity of soil due to natural radionuclides of coal has been found. The specific activities of 226Ra, 228Ra and 40K are equal to those of Greek soils. Radiocesium activity is slightly higher in the first 10 cm layer. The application of chemometrical methods confirmed that the radionulides 226Ra, 228Ra and 40K are natural components of the soil and they do not originate from fly ash.
