    Abstract The aim of work is to contribute to the development of methodologies concerning the selection and characterisation of radon priority areas. The selection of areas was based on risk from indoor radon exposure, expressed in terms of number of expected deaths per year. Radon data come from a survey carried out in the Lazio Region (Italy) and consist of 5297 indoor concentration measurements. Population data were also used. Data showed that dwellings with concentrations above 300 Bq/m

    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 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 new method has been developed for determination of (210)Pb and (210)Po in soil or rock samples containing refractory matrices. The samples were first fused with Na(2)CO(3) and Na(2)O(2) at 600 degrees C for pre-treatment and then (210)Pb and (210)Po were sequentially leached out at 200-250 degrees C with HNO(3)+HF, HClO(4) and HCl. About 10% of the leaching solution was used for (210)Po determination, carried out by spontaneous deposition of polonium on a silver disc from a weakly acidic solution that contained hydroxylamine hydrochloride, sodium citrate and (209)Po tracer, measurement being made by alpha-spectrometry. The remains of the leaching solution were used for determination of (210)Pb, conducted by precipitation as sulphate, purification with Na(2)S as PbS in 6M ammonium acetate, separation from alpha-emitters by an anion-exchange resin column, source preparation as PbSO(4), and measurement with a beta-counter. The procedure has been checked with two certified IAEA reference materials, showing good agreement with the recommended values. The lower limits of detection for 1g of analysed soil or rock samples were found to be 0.75 Bqkg(-1) for (210)Po and 2.2 Bqkg(-1) for (210)Pb. A variety of solid sample species analysed through use of the procedure gave average yields of 90.0+/-9.8% for (210)Po and 88.4+/-7.1% for (210)Pb.

    Abstract The radiological quality in some samples of drinking water collected in Italy has been evaluated in the paper. As far as the measured alpha or beta radionuclides are concerned, the doses for all the analysed samples of drinking water are in the range of 1.80-36.2microSvyr(-1), all being well below the reference level of the committed effective dose (100microSvyr(-1)) recommended by the WHO. As far as each measured alpha or beta radionuclide is concerned, the dose contributions for most of the analysed water samples are in this order: 210Po228Ra>226Ra>234U238U>224Ra>235U, and (210)Po and (228)Ra can yield a significant contribution to the doses from the analysed drinking water samples. As far as the elements are concerned, the dose contributions are 48.0+/-27.9% from radium, 31.7+/-23.1% from polonium, and 20.3+/-14.1% from uranium. The water samples, No. 2, 7, 13, and 15, can lead to a dose of >10microSvyr(-1), mainly due to the dose contribution from (210)Po and 228Ra, especially water samples No. 2 and 13. The obtained data can provide basic information for consumers and competent authorities regarding the internal exposure risk due to drinking water intake, and can possibly serve as a comparison when evaluating the dose contribution from artificial radionuclides released to the environment as a result of any human practices and accidents in the studied area.

    Abstract Some important naturally occurring alpha- and beta-radionuclides in drinking water samples collected in Italy were determined and the radiological quality evaluated. The mean activity concentrations (mBqL(-1)) of the radionuclides in the water samples were almost in the order: 26+/-36 ((234)U)>21+/-30 ((238)U)>8.9+/-15 ((226)Ra)>4.8+/-6.3 ((228)Ra)>4.0+/-4.1 ((210)Pb)>3.2+/-3.7 ((210)Po)>2.7+/-1.2 ((212)Pb)>1.4+/-1.8 ((224)Ra)> 1.1+/-1.3 ((235)U)>0.26+/-0.39 ((228)Th)>0.0023+/-0.0009 ((230)Th)>0.0013+/-0.0006 ((232)Th). The mean estimated dose (microSvyr(-1)) to an adult from the water intake was in this order: 2.8+/-3.3 ((210)Po)>2.4+/-3.2 ((228)Ra)>2.1+/-2.1 ((210)Pb)>1.8+/-3.1 ((226)Ra)>0.94+/-1.30 ((234)U)>0.70+/-0.98 ((238)U)>0.069+/-0.087 ((224)Ra)>0.036+/-0.044 ((235)U)>0.014+/-0.021 ((228)Th)>0.012+/-0.005 ((212)Pb)>0.00035+/-0.00029 ((230)Th)>0.00022+/-0.00009 ((232)Th). It is obvious that (210)Po, (228)Ra, (210)Pb and (226)Ra are the most important dose contributors in the drinking water intake. As far as the seventeen brands of analysed drinking water were concerned, the committed effective doses were in the range of 2.81-38.5 microSvyr(-1), all well below the reference level of the committed effective dose (100 microSvyr(-1)) recommended by the WHO. These data throw some light on the scale of the radiological impact on the public from some naturally occurring radionuclides in drinking water, and can also serve as a comparison for the dose contribution from artificial radionuclides released to the environment as a result of human practices. Based on the radionuclide composition in the analysed waters, comment was made on the new screening level for gross alpha activity in guidelines for drinking-water quality recommended by the WHO, 2004.
