Abstract	In the new procedure for determination of uranium isotopes by α-spectrometry, silica in the leachate of fused soil samples was coated with polyethylene glycol 2000 and eliminated through filtration, and uranium isotopes were separated from other α-emitters with a Microthene-TOPO column and electrodeposited on a stainless steel disc for measurement. It was observed that treatment with HF has negligible contribution on the release of uranium from the leachate containing silicates, so the use of HF for mineralization can be avoided. The reference material IAEA-315 marine sediment was analysed, and the obtained

Article: The fate of the main naturally occurring radionuclides in mussels (Mytilus edulis) and their radiological impact on human beings

Jia, Guogang / Magro, Leandro / Torri, Giancarlo

Environmental monitoring and assessment. 2020 Apr., v. 192, no. 4

2020

Abstract	A comprehensive study was made on the activity concentrations, concentration factors, and radiation exposure impact of the main naturally occurring radionuclides in blue mussels collected in the Mediterranean Sea. The results showed that the concentrations of the measured radionuclides were site-specific and all detectable in gram-size samples of the soft tissues of the mussels, especially, some activity concentrations can reach as high as 16.8–102 Bq kg−1 for 210Po, 16.7–66.8 Bq kg−1 for 40K and 0.602–3.21 Bq kg−1 for 210Pb. The obtained mean concentration factors in the soft tissues of the mussel samples are 6.30 ± 2.40 for 238U and 234U, 4.68 ± 1.73 for 235U, (2.72 ± 1.73) × 104 for 232Th and 230Th, 480 ± 265 for 228Th, 33.3 ± 13.3 for 226Ra, 100 ± 52 for 224Ra and 29.0 ± 14.7 for 228Ra, (1.22 ± 0.72) × 104 for 210Po, 517 ± 280 for 210Pb and 2.57 ± 0.80 for 40K. The estimated mean committed effective doses of 238U, 234U, 235U, 232Th, 230Th, 228Th, 226Ra, 224Ra, 228Ra, 210Po, 210Pb and 40K to an adult due to mussel ingestion are 0.073 ± 0.027, 0.089 ± 0.035, 0.0030 ± 0.0011, 0.128 ± 0.098, 0.117 ± 0.081, 0.056 ± 0.031, 0.145 ± 0.058, 0.0487 ± 0.0250, 0.395 ± 0.200, 352 ± 209, 6.00 ± 3.25 and 1.74 ± 0.54 μSv a−1, respectively. Among the elements or nuclides, 210Po is the dominant dose contributor which contributes 96.9% of total dose fraction, and the relative dose contribution is in the order of 210Po > 210Pb > 40K > radium ≥ thorium ≥ uranium.

Abstract	Radium (Ra) isotopes are important from the viewpoints of radiation protection and environmental protection. Their high toxicity has stimulated the continuing interest in methodology research for determination of Ra isotopes in various media. In this paper, the three most routinely used analytical techniques for Ra isotope determination in biological and environmental samples, i.e. low-background γ-spectrometry, liquid scintillation counting and α-spectrometry, were reviewed, with emphasis on new methodological developments in sample preparation, preconcentration, separation, purification, source preparation and measurement techniques. The accuracy, selectivity, traceability, applicability and minimum detectable activity (MDA) of the three techniques were discussed. It was concluded that the MDA (0.1mBqL(-1)) of the α-spectrometry technique coupled with chemical separation is about two orders of magnitude lower than that of low-background HPGe γ-spectrometry and LSC techniques. Therefore, when maximum sensitivity is required, the α-spectrometry technique remains the first choice.

The accuracy, selectivity, traceability, applicability and minimum detectable activity (MDA) of the three techniques were discussed. It was concluded that the MDA (0.1mBqL⁻¹) of the α-spectrometry technique coupled with chemical separation is about two orders of magnitude lower than that of low-background HPGe γ-spectrometry and LSC techniques. Therefore, when maximum sensitivity is required, the α-spectrometry technique remains the first choice.

Abstract	A radiological survey on the iron- and steel-making plant ILVA Taranto (Italy) was mainly focused on contamination source-term investigation and exposure impact evaluation of the volatile radionuclides 210Po and 210Pb. The activity concentrations of 210Po and 210Pb in the raw materials, dust particles, surficial soils and atmospheric particulate samples collected in the area of ILVA Taranto were determined. The results showed that the activity concentrations in the raw materials were in the range of 3.46-17.9 Bq kg(-1) for 210Po and 3.50-16.8 Bq kg(-1) for 210Pb, which could create maximum annual inventories of 2.64 × 1011 Bq of 210Po and 2.71 × 1011 Bq of 210Pb if a total quantity of 22 Mt per year raw materials was consumed in the plant. The activity concentrations in dust particles emitted from the chimney of the ILVA Taranto were in the range of 5.91-85.6 kBq kg(-1) for 210Po and 5.44-34.6 kBq kg(-1) for 210Pb, releasing more 210Po than 210Pb. The activity concentrations in surficial soils were in the range of 49.3-140 Bq kg(-1) for 210Po and 51.6-150 Bq kg(-1) for 210Pb, a variation of the activity concentrations being observable with distance. The activity concentrations in atmospheric particulate were in the range of 43.1-564 μBq m(-3) for 210Po and 618-1099 μBq m(-3) for 210Pb, and it was observed that the mass specific activity concentrations of 210Po and 210Pb in the atmospheric particulate are one to three orders of magnitude higher than that found in the top soil. After deduction of the background contribution, about 27.2 μSv per year of the estimated committed effective dose at mean and 49.2 μSv per year at maximum could be attributed to 210Po and 210Pb emitted from the chimney of the ILVA Taranto and inhaled by the public in the form of atmospheric particulate, of which about 63.5-69.0% was the contribution of 210Pb. No specific interventions should be required, as far as only inhalation of 210Po and 210Pb are concerned.

Abstract	A radiological survey on the iron- and steel-making plant ILVA Taranto (Italy) was mainly focused on contamination source-term investigation and exposure impact evaluation of the volatile radionuclides 210Po and 210Pb.
