“…This is evident from generally lower activity concentrations of 137 Cs in soil in this part of Croatia than elsewhere in the country ( 5 ). Our earlier finding ( 1 ) that the A of 137 Cs in moss samples from the Kopački rit was unusually low (0.7–13.1 Bq/kg) in 2018 is consistent with that, since the maximum value measured (and extrapolated to 2018) was 65 Bq/kg in Serbia ( 6 ), 400 Bq/kg in Greece ( 7 ), 300 Bq/kg in Armenia ( 8 ), 10,680 Bq/kg in Austria ( 9 ), and 360 Bq/kg in Turkey ( 10 ). In all these locations, the primary source of measured 137 Cs was the Chernobyl accident, and the distances between all these countries and Chernobyl are not significantly different.…”

The invasion of Ukraine and military operations around Ukrainian nuclear power plants and other nuclear facilities have prompted us to search for radiocaesium in mosses from the Kopački Rit Nature Park in Croatia, since mosses are known bioindicators of airborne radioactive pollution, and Kopački Rit is a known low radiocaesium background area. Sampling was finished in August 2023, and our analysis found no elevated radiocaesium levels. Kopački Rit therefore remains a suitable place for future detection of anthropogenic radioactive pollutants.

“…Due to their strong absorption and retention of airborne substances 15 – 17 , and in spite of additional pathways of the absorption of matter, mosses have been recognised as reliable biomonitors for atmospheric pollution. This has been used worldwide to monitor environmental stress caused by numerous non-radioactive 18 – 22 and radioactive 9 , 18 , 22 – 29 elements. Since mosses appear in different habitats, they have been for a long time used to record the dynamics of pollution within small areas such as industrial zones 30 – 32 , cities 14 , 33 or motorways 34 , 35 .…”

“…In the below listing, the data refer to the situation extrapolated to 2018, calculated by taking into account the radioactive decay, original values, and the elapsed time. The A of 137 Cs in mosses from the Plitvice Lakes National Park in Croatia was in the range 25–1460 Bq kg −1 (sampled in 2011–2012) 23 , in Armenia 3–300 Bq kg −1 (2018–2020) 29 , in Austria 870–10,680 Bq kg −1 (2006) 27 , in Greece 0–400 Bq kg −1 (2016) 18 , in Turkey 30–360 Bq kg 1 (2007) 25 , and in Serbia 6–65 Bq kg −1 (2008) 28 .…”

We studied activity concentrations of radionuclides in the Kopački Rit Nature Park using mosses as bioindicators. This area of intact nature is at the tripoint of Croatia, Hungary, and Serbia, being located basically at the centre of the middle Danube River basin. Therefore, it can be easily affected by airborne pollution from various locations in the Middle Europe and beyond. The goal of our research was to assess whether the Park could serve as a location where any new radioactive contamination could be sensitively detected, which implied a necessity for low activity concentrations at the present time. Our gamma-ray spectrometry revealed the presence of only one anthropogenic gamma emitter, that is, 137Cs. Its activity concentration in the mosses ranged from 0.7 to 13.1 Bq kg−1, being low indeed. Another radionuclide in our focus was 210Pb. Generally, its elevated concentrations may signify ecologically undesirable human activities that involve naturally occurring radioactive matter. The activity concentration of 210Pb in the mosses was in the range from 183 to 690 Bq kg−1. This did not depart from the results of other similar studies and was again low enough for a detection of possible excess amounts of this radionuclide in the future.

“…Conducting nuclear tests, the use of radioactive sources not only in industry, but also in medicine, agriculture leads to significant changes in the radiation situation. Territories with a high content of not only artificial, but also natural radionuclides are beginning to appear [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

The article discusses the study of the content of natural radionuclides (40К, 226Ra, 228Th) in ordinary chernozems of the Kamennaya Steppe reserve. The studies were carried out in soils not subject to any anthropogenic impact under the forest belt, as well as in the mowed and unmowed fallow. The development of nuclear energy, the widespread use of radioactive sources in industry, medicine, and agriculture has led to an increase in the content of not only artificial, but also natural radionuclides. It was revealed that the accumulation of natural radionuclides is determined by the organic matter of soils. In the chernozems under the forest belt, with the highest carbon content of organic compounds, a slightly larger amount of natural radionuclides (40К, 226Ra, 228Th) is noted. This phenomenon occurs due to selective complex formation with soil organic ligands, which enrich the studied soils. The highest coefficient of variation is typical for 226Ra, which indicates the inhomogeneity of the activity of the radionuclide in space. 40К and 228Th are characterized by lower values of this indicator. Activity data radionuclides are more uniformly distributed in space. The results obtained are recommended to be used in monitoring studies. In order to prevent soil contamination with radionuclides.
