“…The absorption rate of these radionuclides is highly dependent on the concentration of activity in the soil. Root absorption depends on soil properties such as pH, mineral composition, organic matter content, and nutritional status as well as metabolic and physiological characteristics of plant species [12,33]. The uptake of radionuclides into cassava leaves and grass is one of the many factors for the migration of natural radionuclides to human from the environment through the food chain [34,35].…”

The existence of a Coal-Fired Power Plant (CFPP) is suspected to affect the environment quality, especially the increment of natural radionuclides content which is found in coal as raw material. Therefore, systematic analysis of natural radionuclides ( 210 Pb, 234 Th, 238 U, 228 RA, 40 K, 226 RA and 232 Th) in water, soil, and plant were conducted to establish a database of environmental contamination in the area around a CFPP. This research was conducted in the area around Adipala Cilacap CFPP which operates with two towers. Samples were taken from three locations around the Adipala CFPP based on the secondary wind direction data from Indonesian Agency for Meteorological, Climatological, and Geophysics in the 2018 dry season. Samples were prepared in the Radiochemistry Laboratory, Center for Accelerator Science and Technology, BATAN. The concentration of radioactivity in environmental samples were analyzed using gamma spectrometry with a high purity germanium detector for 24hours after reaching its secular equilibrium. The result of samples analyses shown that the mean value of the radionuclides specific activities ( 210 Pb, 234 Th, 238 U, 228 RA, 40 K, 226 RA and 232 Th) for water, cassava leaves, grass, and soil were 0.789 Bq/L, 14.685 Bg/kg, 15.036 Bq/Kg, and 75.083 Bq/kg, respectively. The mean of radium equivalent activity (Ra eq ) for water, cassava leaves, grass, and soil were 1. 692, 30.792, 18.699 and 137.513 Bq/kg, respectively. The absorbed dose rate (ADR) for water, cassava leaves, grass, and soil were 0.775, 14.332, 8.627, and 64.135 nGy/h, respectively, whilst the annual effective dose rate (AEDR) were 0.004, 0.070, 0.042, and 0.315 mSv/y. The mean of external and internal hazard indices (H ex and H in ) for water, cassava leaves, grass, and soil were 0.005 and 0.006, 0.083 and 0.129, 0.050 and 0.078, and 0.371 and 0.554, respectively, while the mean of excess lifetime cancer risk (ELCR) wre 0.014×10 -6 , 0.246×10 -6 , 0.148×10 -6 , and 1.101×10 -6 . According to the calculation of radiation hazard index in this research, it was understood that all parameters of all samples were within acceptable limits by the world average value reported by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).

“…This finding raises concerns about the potential threat to people living in the area who consume chickpeas regularly. In terms of green leafy vegetables, U radioactivity concentration is more pronounced in the roots of the greens [55,56]; however, SWC stands out with a particularly high translocation coefficient of 5.5 × 10 −3 [57]. Among non-leafy vegetables, such as PTT and BRN [58], they also demonstrate notably high translocation coefficients, while BET had an accumulation up to 2.98 Bq/kg [59], and CCM showed higher accumulation with median value of 0.42 Bq/kg [60].…”

Uranium (U) and fluoride (F−) contamination in agricultural products, especially vegetable and cereal crops, has raised serious concerns about food safety and human health on a global scale. To date, numerous studies have reported U and F− contamination in vegetable and cereal crops at local scales, but the available information is dispersed, and crop-wise differences are lacking. This paper reviews the current status of knowledge on this subject by compiling relevant published literatures between 1983 and 2023 using databases such as Scopus, PubMed, Medline, ScienceDirect, and Google Scholar. Based on the median values, F− levels ranged from 0.5 to 177 mg/kg, with higher concentrations in non-leafy vegetables, such as Indian squash “Praecitrullus fistulosus” (177 mg/kg) and cucumber “Cucumis sativus” (96.25 mg/kg). For leafy vegetables, the maximum levels were recorded in bathua “Chenopodium album” (72.01 mg/kg) and mint “Mentha arvensis” (44.34 mg/kg), where more than 50% of the vegetable varieties had concentrations of >4 mg/kg. The concentration of U ranged from 0.01 to 17.28 mg/kg; tubers and peels of non-leafy vegetables, particularly radishes “Raphanus sativus” (1.15 mg/kg) and cucumber “Cucumis sativus” (0.42 mg/kg), contained higher levels. These crops have the potential to form organometallic complexes with U, resulting in more severe threats to human health. For cereal crops (based on median values), the maximum F− level was found in bajra “Pennisetum glaucum” (15.18 mg/kg), followed by chana “Cicer arietinum” (7.8 mg/kg) and split green gram “Vigna mungo” (4.14 mg/kg), while the maximum accumulation of U was recorded for barley “Hordeum vulgare” (2.89 mg/kg), followed by split green gram “Vigna mungo” (0.45 mg/kg). There are significant differences in U and F− concentrations in either crop type based on individual studies or countries. These differences can be explained mainly due to changes in geogenic and anthropogenic factors, thereby making policy decisions related to health and intake difficult at even small spatial scales. Methodologies for comprehensive regional—or larger—policy scales will require further research and should include strategies to restrict crop intake in specified “hot spots”.
