Determination of the activity level of gamma radionuclides -artificial 137Cs and for comparison -natural 40K and the selected heavy metals in the Tatra Mountains ecosystem.

This paper presents the results of determination of artificial 137 Cs and natural 40K  activity concentrations and same heavy metals in soil samples from Tatra Mts. Results  show some differences in the vertical distribution and of examined radionuclides and metals. The change of  activity of 137Cs in the  soil samples depends mostly on the soil volume density and on the concentration of organic material. The state of "zero" 137Cs activity was developed in the form of maps.
