“…Vegetable samples were collected from various farms in clean polythene bags and washed carefully to remove adhered soil particles. The non-edible part was separated and the edible part was oven-dried at 105°C (Moran-Hunter and O'Dea 2008; Rahman et al 2008). After drying, the samples were pulverized in a mixer, charred in open flame using a semitransparent silica dish, and subjected to white ashing in furnace at 450°C to avoid loss of alkali metals by overheating.…”

The 137 Cs and 40 K activities and transfer factors from soil to vegetables, grass, and milk from villages located around Tarapur Atomic Power Station (TAPS) were determined using high-resolution gamma spectrometry. A total of 32 soil, 21 vegetable, 23 dry paddy grass, and 23 milk samples were collected from 23 different agricultural farms from various villages around TAPS to determine transfer factors for natural environment. The mean concentration values for 137 Cs and 40 K in soil, grass, and milk were 2.39± 0.86 Bq kg −1 , 0.31 ± 0.23 Bq kg −1 , and 12.4 ± 5.7 mBq L − 1 and 179±31 Bq kg − 1 , 412± 138 Bq kg −1 , and 37.6±9.3 Bq L −1 , respectively, for soil-grass-milk pathway. In the soil-vegetation pathway, the mean concentrations values for 137 Cs and 40 K were 2.15±1.04 Bq kg −1 , 16.5±7.5 mBq kg −1 , and 185±24, 89±50 Bq kg −1 , respectively. The evaluated mean transfer factors from soil-grass, grass-milk, and soil-vegetation for 137 Cs were 0.14, 0.0044, and 0.0073 and that of 40 K were 2.42, 0.0053, and 0.49, respectively. Only 15 out of total 44 milk and vegetable samples were detected positive for 137 Cs, indicating a very low level of bioavailability.

“…In addition to accidental nuclear releases, radionuclides can be released from low-level radioactive waste disposal facilities, which can lead to ecosystem contamination [39,40]. The immobilization of stable isotopes in aqueous solutions was used in most previous works to simulate radioactive isotopes since employing the actual radioactive wastes represents a significant radiation hazard, and the chemical properties of radioactive isotopes can be simulated with sufficient accuracy by non-radioactive isotopes [6].…”

Numerous low-level and intermediate-level radioactive wastes are generated from the decommissioning processes of nuclear power plants; these wastes are immobilized to prevent the release of radionuclides under disposal conditions. In this study, we investigated the leaching behavior of Cs, Sr, Co, and Eu, which are common in immobilized decommissioning wastes. Ordinary Portland cement (OPC) was used as an immobilization agent. During the test, leaching of the nuclides occurred in the order of Cs, Sr, Co, and Eu and decreased over time. The results showed that 41.4% of the total Cs leached over 90 days, although the other elements leached in quantities less than 1.5%. CaCO3 was precipitated by the release of cementitious materials, indicating carbonation of the leachate. The leachability indexes in all cases exceeded the acceptable criteria (>6). The results of the present study suggest that OPC can be effectively used as a binding material to immobilize nuclides (Cs, Sr, Co, and Eu) contained in decommissioning wastes.

“…Tsukada and Nakamura (1999) have shown that the TF of Cs isotopes is negatively correlated with K concentration in the soil. While 137 Cs uptake has been widely studied either in laboratory or in natural conditions, only few data are available for 60 Co (IAEA, 1994;Rahman et al, 2008).…”
