Determination of 241Pu in the environmental samples.
More than 70 soil samples were analysed in the last several years; results are in the range 0.10-3.74 Bq/kg dry soil, with a median of 0.49 and mean of 0.59 Bq/kg dry soil. From the analysis of more than 40 moss samples, the range of activity concentration was found to be 0.002-2.80 Bq/kg fresh mass with median 1.00 and mean value 0.30 Bq/kg fresh mass. In Hungary, the plutonium contamination comes from global fallout determined by the nuclear weapon tests, while is confirmed by plutonium isotope ratios.
