Abstract:The results of polonium ((210)Po) and lead ((210)Pb) determination in different environmental soil samples collected in the vicinity of the phosphogypsum stack in Wiślinka (northern Poland) are presented and discussed in this paper. The (210)Po and (210)Pb concentrations in soil samples from the phosphogypsum stack recorded in this study are significantly higher only in areas that are close to the heap. The relationship between atmospheric deposition and elevated analyzed radionuclides concentrations in top so… Show more
“…Long-term studies of the impact of phosphogypsum heap in Wiślinka have proved that this area can be a threat to the surrounding environment. Detailed studies of Wiślinka phophogypsum heap were described by Boryło and co-workers [6][7][8]21] and Olszewski and coworkers [22,23]. In this province higher 210 Po concentration and effective dose were also measured in Gdańsk city, where the petrochemical industry is developing (from 0.128 ± 0.005 to 0.142 ± 0.012 Bq kg −1 and from 0.094 ± 0.004 to 0.104 ± 0.009 μSv year −1 respectively.…”

“…The largest share (73.8%) in the value of the effective dose received by a statistical Pole is natural radiation [2]. Among the sources which have an impact on environmental pollution by natural radionuclides are: activities of mining and power industry and the presence of various types of landfills, fertilization; exhalation of radon 222 Rn from the surface of the earth and building materials [2][3][4][5][6][7][8].…”
This work shows significant variations in the values of 210 Po in different analyzed Polish voivodeships. Statistical analysis of 210 Po activity concentrations in honey samples showed significant differences between place of honey collecting, kind of honey and morphological structure of plants from which bees collected nectar.

“…The phosphogypsum waste heap contains most of radiotoxic nuclides: polonium 210 Po, (and its mother radionuclide 210 Pb), radium 226 Ra and uranium ( 234 U and 238 U). In the Wiślinka waste heap the estimated activity in 16 million tons of phosphogypsum contains about 4.51 × 10 11 Bq for 234+238 U [22–32]. Fig.…”
In the study the activities of polonium 210Po and uranium 234U, 238U radionuclides in moss and lichen samples were determined using the alpha spectrometry. Different lichens and mosses were collected around the Sobieszewo Island (northern Poland) and investigated for potential use as biomonitors for 210Po and 238U deposition. Mosses and lichens have a high efficiency in capturing 210Po and 238U from atmospheric fallout. The obtained results showed that 210Po, 238U concentrations are changing in analyzed thallophytes samples depending on the type of thallus.
“…Phosphogypsum (CaSO 4 ·2H 2 O) is a by-product of this reaction [ 1 ]. Phosphogypsum stockpile in Wiślinka contains about 16 million ton of phosphogypsum [ 2 ]. The essence of radiotoxicity of the phosphogypsum is both gamma radioactivity and high content of natural alpha radioactive elements ( 234 U, 235 U, 238 U, 226 Ra, 210 Po) and also beta emitter ( 210 Pb), which could be leached by rain and bioaccumulated in plants and animals as well as in humans.…”

“…In the process of phosphoric acid production about 80 % of uranium is associated with the phosphoric acid fraction, while about 90 % of the 210 Po and 210 Pb is bound to the phosphogypsum fraction [ 1 , 3 ]. Radionuclides might be leached by wet precipitation and transported through groundwaters to plants where they are accumulated [ 2 , 4 – 8 ].…”
The aim of this work was to determine the concentrations of uranium (234U, 235U, 238U), polonium (210Po) and lead (210Pb) radioisotopes in water samples and to explore the impact of the phosphogypsum stack on the Martwa Wisła waters. The 238U, 210Po and 210Pb concentrations in analyzed water samples reached maximum values of 11.7 ± 0.3, 2.0 ± 0.1 and 3.2 ± 0.1 mBq L−1 and activity ratios were maximally 1.18 ± 0.01 for 234U/238U, 0.041 ± 0.018 for 235U/238U and 0.69 ± 0.10 for 210Po/210Pb. The obtained results suggest that this impact is rather insignificant and does not affect significantly the Martwa Wisła river.
