Soil contamination level with 239+240 Pu of Lublin region was determined using the alpha spectrometric method. Results were compared with similar data from the study performed 15 year earlier. Decrease in total 239+240 Pu concentration and reducing quantity of Chernobyl fraction (up to almost negligible value of 1 %) has been observed in upper soil layer. Determination of 239+240 Pu concentration in soil profile layers allows calculating a vertical migration velocity of plutonium applying a compartment migration model. It was found that 239+240 Pu migration rate varies depending on soil type from 0.29 cm year -1 in Podsols to 0.58 cm year -1 in Fluvisols with mean value of 0.5 cm year -1.

Study on the rate of plutonium vertical migration in various soil types of Lublin region (Eastern Poland)
