238Pu, 239+240Pu, 241Am, 90Sr and 137Cs in mountain soil samples from the Tatra National Park (Poland)

Behaviors and transfers of anthropogenic radionuclides (137Cs, 239+240Pu and 241Am) in a protected alpine wetland (France)

“…Similar conclusions were obtained by Mietelski et al in soil samples impacted by the global fallout ( 238,239?240 Pu and 241 Am) and by both the Chernobyl accident in surface and global fallout in-depth for 137 Cs. In these highly organic soils, a high migration rate was reported for 238,239?240 Pu, a lower for 137 Cs and an intermediate for 241 Am [57]. Thus, despite the different origins of the RNs the vertical migrations in this soil and the sediment cores seem to be maximum for Am, minimum for Cs and intermediate for Pu.…”

The activity of selected gamma radionuclides in the Tatra National Park

“…Studies in the Tatra Mountains were performed during 15 years [8][9][10][11][12][13][14][15][16][17][18][20][21][22][23]. Therefore in order to keep results comparable, the measured activities of 137 Cs are recalculated to the date of the 1 st September 2000.…”

“…Especially important artificial radionuclide is 137 Cs for the reason of its rather long half-life (30,08 years) and large dispersion in the environment. Between the years 2000 -2015 there were made extensive studies of anthropogenic 137 Cs and natural 40 K activity levels in soil [8][9][10][11][12][13][14][15][16][17][18]. This paper presents the research result concerned on the area of the Tatra Mountains.…”

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.

“…Studies in the Tatra Mountains were performed during 15 years [8][9][10][11][12][13][14][15][16][17][18][20][21][22][23]. In order to keep results comparable, the measured activities of 137 Cs (T 1/2 = 30,05 years) are recalculated to the date of 1st September 2000.…”

“…Between the years 2000-2015 there were made extensive studies of anthropogenic 137 Cs and natural 40 K activity levels and concentrations of selected heavy metals in soil [8][9][10][11][12][13][14][15][16][17][18]. These studies were carried out in several southern Polish mountain ecosystems.…”
