“…Shayeb et al [34] compaJapanaesethe 137Cs activity concentrations in date and soil samples collected from different regions of Saudi Arabia and they reported the activity in soil to be 10.2 ± 2.1 Bq kg -1 and the activity in date samples to be below the limit of detector. In a study carried out using tea leaves, 137Cs activity concentration was found to be <0.4 Bq kg -1 in the leaves and 3±1-10±1 Bq kg -1 in the soils, whereas TF (137Cs) was found to be belwo the limit of detector [4].

“…The 238U activity concentration found in the present study was higher in comparison to the results reported in the literature. Examining several tree species and epiphyte plants, Manigandan et al [4] reported the mean 238U activity concentration to range between 9.6 ± 0.4 and 11.4 ± 0.4 and TF value to range between 0.249 and 0.313. However, Tshivhase et al [28] reported the 238U activity concentration to be 31.36±9.40, 0.02±0.01, and 0.16 ±0.14 Bq kg -1 and TF value to be 0.19±0.06, 0.307±0.89, and 0.11±0.01 Bq kg -1 , respectively.…”

“…Moreover, fossil fuels, nitrogenous fertilizer industry, and synthetic fertilizer technology might cause the release of natural radionuclides into the environment [1,2]. Natural radiation sources consist of natural radionuclides naturally existing in nature such as 238U, 232Th, and 40K and the 238U and 232Th degradation series products (226Ra and 222Rn), while the artificial radionuclides such as 90Sr, 137Cs, and 131I are released to the environment through nuclear accidents and nuclear weapon trials [3,4]. Natural and artificial radionuclides bind to the inorganic matter in soil and sediments through air and water and accumulate in herbal tissues via the roots.…”

In this study, the effect of Cd and Zn application on the activity concentration and transfer factors in the Ladybird, Boxwood, and Gold Tassel leaves was investigated using gamma-ray spectrometry. The mean concentrations (in Bq kg-1) of radionuclides in the studied soil samples were found to be 289.40±32.47 for 238U, 241.76±27.47 for 232Th, 783.63±83.46 for 40K, and 31.44±5.63 for R 137Cs while the respective values in the studied species were 168.6±20.1- 288.8±34.5, 145.9±19.1-250.3±32.4, 434.6±52.2-828.4±99.4, and 16.1±1.8-28.3±3.3. The activity concentrations were found to be at the lowest in the control group and 400 µM Zn for all three species, and at the highest level at 25 µM Cd in general. The order of radionuclides by the highest activity concentrations was 40K>238Uz232Th>137C, whereas the order of species was Gold Tassel>Boxwood>Ladybird. TF (232U, 232Th, 40K, and 137Cs) values were found to be between 0.583 and 0.998, between 0.604 and 1.036, between 0.555 and 1.057, and between 0.513 and 0.899. And also, while the order of species by the activity concentration was Gold Tassel>Boxwood>Ladybird the order of species by the TF values was Boxwood>Gold Tassel>Ladybird. In conclusion, plants’ radionuclide activity concentrations were found to be at the highest level in 25 µM Cd group and at the lowest level in the control group. Given all the data, it can be stated that a low dose of Cd was effective on the radioactivity concentrations and Gold Tassel could be used as the indicator plant in radiation pollution.
