“…[18] Uranium (as UO 2+ ) is more easily transported to plants from soil via roots than other actinides, although the deposition of uranium is also important way of surface contamination of plants. [19,20] According to the World Health Organization (WHO) the limit of permissible alpha and beta emitters in drinking water (generally: 210 Po, 226 Ra, 234 U, 238 U) is 0.1 Bq·dm −3 . [21] Materials and methods All results for plants were given in wet weight because of different moisture condition.…”

The aim of this work was the determination of the impact of phosphogypsum waste heap in Wiślinka (northern Poland) for radiological protection of zone around waste heap. These studies are very important for the estimation of natural alpha radionuclides contents in the vicinity of phosphogypsum waste heap and for environmental pollution assessment of this area. The process of bioaccumulation of radionuclides in interior plants parts prove to examine their origin sources, too. The activity of (210)Po, (234)U, and (238)U were measured using an alpha spectrometer. The values of uranium and polonium concentration in water with immediate area of waste heap are considerably higher than in the waters of the Martwa Wisła river. The values of activity ratio (234)U/(238)U are approximately about one in the phosphogypsum (0.97 ± 0.05) and in the water of retention reservoir and pumping station (0.92 ± 0.01 and 0.99 ± 0.08), while in the water from the Martwa Wisła river they are slightly higher than one (1.03 ± 0.07 and 1.17 ± 0.06). In the analyzed plants species the highest amounts of polonium and uranium were found in ruderal plants samples (between 51 ± 1 and 89 ± 1 for (210)Po; between 36 ± 3 and 68 ± 3 for (238)U) as well as hygrophilous plant samples (18 ± 1 and 84 ± 3; 42 ± 2 and 130 ± 4, respectively for (210)Po and (238)U). The more amounts of (210)Po and (238)U radionuclides were accumulated mainly in the roots of plant species in comparison to green parts. The general conclusion of realized study is higher influence of phosphogypsum on radioactive contamination of environmental zone around heap waste in Wiślinka (northern Poland).

“…The soil is of relatively low uranium and radium concentrations (Bou-Rabee et al 1995) with a reported range of 1.80 -28.20 Bq kg Ϫ1 and an average value of 11.77 Bq kg Ϫ1 for 226 Ra (Bou-Rabee 1997), while the world average for 226 Ra is 35 Bq kg Ϫ1 (UNSCEAR 2000).…”

Indoor radon measurements were carried out in 300 dwellings in Kuwait using duplicate sets of charcoal detectors. Measurements were made at three different locations in the dwellings: living rooms, bedrooms, and basements. The results show that the radon concentration in the dwellings of Kuwait was found to vary in the range of 4.0-241.8 Bq m(-3) with a mean value of 32.8 Bq m(-3), and most values are confined within the range of 10-50 Bq m(-3) for all locations with few cases above the value of 100 Bq m(-3). Overall results show that the indoor radon concentration levels in Kuwait are relatively low, which is attributed to the use of air conditioning in summer and possible natural ventilation in winter. The radon concentration in basements was found to be relatively higher when compared to other rooms of the dwellings.

“…Various uranium minerals contain from 50 to 90% of this element. Naturally occurring uranium contains three alpha emitting radionuclides: 238 U (99.2745%), 235 U (0.7200%), 234 U (0.0055%) [2,3]. The isotope 238 U is the parent nuclide of the radioactive decay uranium-radium series.…”

“…Natural uranium concentration in rivers varies linearly with salinity [1]. The higher concentration of uranium in natural environment may be also the result of human activity -nuclear industry, combustion of fossil fuels, production and use of phosphate fertilizer [8][9][10] use of depleted uranium for military purposes [2,10,11]. Uranium is relatively highly toxic to humans, both chemically and radiologically (its progeny are highly radioactive).…”

were measured using alpha spectrometry. In winter, the highest concentration of uranium isotopes and total uranium was in the Vistula River water from Malbork (13.13 ± 0.22 Bq m −3 for 234 U, 12.45 ± 0.21 Bq m −3 for 238 U and 1.02 ± 0.30 mg m −3 for total uranium), and the lowest was in water from Dȩblin (1.73 ± 0.07 Bq m −3 for 234 U, 1.55 ± 0.07 Bq m −3 for 238 U and 0.13 ± 0.09 mg m −3 for total uranium). In analyzed river samples uranium isotopes 234 U and 238 U are not in the radioactive equilibrium state. The values of 234 U/ 238 U activity ratio lie between 1.05-1.70. During spring, the highest concentration of uranium isotopes and total uranium was found in the Vistula River water from Malbork (12.36 ± 0.19 Bq m −3 for 234 U, 10.77 ± 0.17 Bq m −3 for 238 U and 0.88 ± 0.25 mg m −3 for total uranium), and the lowest was in water taken from Sandomierz (5.77 ± 0.14 Bq m −3 for 234 U) and Kraków (4.08 ± 0.11 Bq m −3 for 238 U and 0.33 ± 0.18 mg m −3 for total uranium). The values of 234 U/ 238 U activity ratio lie between 1.15-1.64. In summer, the highest concentration of uranium isotopes and total uranium was found in the Vistula River water samples taken from Malbork (8.22 ± 0.21 Bq m −3 for 234 U, 7.60 ± 0.21 Bq m −3 for 238 U and 0.62 ± 0.29 mg m −3 for total uranium), and the lowest was in water from Sandomierz (6.37 ± 0.12 Bq m −3 for 234 U) and Kraków (3.56 ± 0.19 Bq m −3 for 238 U and 0.29 ± 0.33 mg m −3 for total uranium). The values of 234 U/ 238 U activity ratio lie between 1.08-1.95. In autumn the highest concentration of uranium isotopes and total uranium was in the Vistula River water from Malbork (17.80 ± 0.25 Bq m −3 for 234 U, 15.12 ± 0.23 Bq m −3 for 238 U and 1.23 ± 0.34 mg m −3 for total uranium) and the lowest was in water from Toruń (8.15 ± 0.49 Bq m −3 for 234 U) and Kraków (6.34 ± 0.47 Bq m −3 for 238 U and 0.52 ± 0.78 mg m −3 for total uranium). The values of 234 U/ 238 U activity ratio lie between 1.10-1.74. Annually, the southern Baltic Sea is enriched by about 507 GBq uranium isotopes 234 U and 238 U, with 490 GBq going to the Gdańsk Bay and 16.5 GBq to Vistula Lagoon. The highest surface 238 U runoff was observed in spring (to 1200 kBq km −2 quarter −1 for catchment's area), the lowest in summer for Bug with Narew catchment's area to 20 kBq km −2 quarter −1 ). These studies are very important
