“…Some studies exposed a high contamination of food products with 210 Po, e.g., seafood, especially shellfish, leafy vegetables and infant formulas [ 17 , 20 , 46 , 47 , 48 ]. Fruit wines from two locations (Małopolska and Lubelskie) were similarly contaminated with 210 Po radionuclides as leafy vegetables, as analyzed in Italy, Vietnam and reported by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) [ 17 , 46 , 47 ]. Additionally, wine samples from these two locations contained similarly high 210 Po activity concentrations, as found in infant formulas in Slovenia [ 20 ].…”

“…Meli et al [ 17 ] reported that the consumption of basic food products (milk, meat, grain, roots vegetables) contributed to the radiation dose due to 210 Po ingestion ranging 2.1–4.5 μSv/year, which was about 2–3 fold higher than the effective dose from fruit wine intake estimated in our study [ Table 3 ]. More recent studies highlighted that the consumption of seafood, especially shellfish in New Zealand, and the consumption of water spinach in Vietnam were the highest contributors to human exposure to the 210 Po isotope [ 11 , 47 ].…”

Study of Polonium (210Po) Activity Concentration in Fruit Wines Derived from Different Locations in Poland

This study aimed at assessing the activity concentration and the annual effective dose of polonium-210 (210Po) in fruit wines derived from four locations in Poland (Warmian–Masurian, Podlaskie, Lubelskie and Małopolskie voivodeships). The fruit wines differed significantly (p < 0.05) in 210Po activity depending on the production site, with the Małopolskie site having the highest activity (61.4–221.4 mBq/L) and the Podlaskie having the lowest (3.5–97.1 mBq/L). The site differentiation was due to environmental conditions—soil parameters (uranium concentration), precipitations and terrain characteristics, e.g., the proximity of the lakes. The increased activity concentration of 210Po in samples from Małopolska compared with the other sites probably derived from the environment polluted with aqueous wastes and particulate air pollution. The annual effective dose due to the ingestion of fruit wines ranged from 0.112 to 1.214 µSv/year. These levels of exposure are safe according to the WHO criterion (0.1 mSv per year for ingestion) and to the IAEA reference level for public exposure including food (1 mSv per year). Summing up, the data obtained provide information on the activity concentration of 210Po in fruit wines and increase databases on the natural radioactivity of foodstuffs. Future work is needed to examine 210Po activity in samples from all vineyard regions in Poland.

“…Natural radionuclides from different sources in the environment, even in our bodies can originate from weathering of the earth's crust (rocks, soils, ores), food consumption, mining activity, and fertilizer materials (Azeez et al 2019, Querfeld et al 2019, Takagi et al 2019, Van et al 2020a, 2020b, 2020c, Loat et al 2021, Van et al 2021a, 2021b, 2021c, 2021d). In the air, radionuclides such as 222 Rn and 220 Rn originate from the alpha decay of 226 Ra in the 238 U series and 228 Ra ( 224 Ra) in the 232 Th decay series, respectively (Omori et al 2016).…”

The outdoor ²²²Rn and ²²⁰Rn concentrations at 320 sampling points at 1m above the ground in different sites surrounding rare earth element (REE) and uranium mines from northern Vietnam were measured using the RAD7. Results showed that ²²²Rn concentrations were always higher than ²²⁰Rn concentrations with large variation ranges from 25.7 to 573 Bq/m3 and from 18.5 to 385 Bq/m3, respectively. The high correlation between ²²⁰Rn and ²²⁸Ra concentrations in surface soil of the studied sites were observed. The highest ²²⁰Rn and ²²²Rn concentrations are found at the sampling points of the REE NX-Lai Chau site. The ²²⁰Rn and ²²²Rn activities surrounding the REE mines were found to be higher than those surrounding the uranium mines. The average annual committed effective doses originated from the inhalation of ²²⁰Rn and ²²²Rn outdoor concentrations is about five times higher than the worldwide average value as reported in UNSCEAR (2000).

Determination of naturally radionuclides have been known well as an important topic in environmental study in recently. One of the most toxic radioisotope in nature, a daughter product of 238U decay chain is 210Po (polonium). The improvement and optimizations methods for determination of this attractive isotope are still presenting so far. In this paper, a new improved method was elaborated for 210Po determination in thermal water sample. In the proposed method, analytical optimization of spontaneous/auto deposition does not use Teflon cup, magnetic stirring or any preparing equipment/item only normal glass and a side of square silver. In addition, the optimization was neglected with absent of purification of polonium (Liquid-liquid extraction methods/Ion exchange chromatography/Extraction chromatographic separations). The outcome of optimal procedure were simplify, less time consuming, great reduction of costs with chemical recovery >80% and could apply for any liquid environmental samples.
