| Abstract | From 1979 to 1989, ten million tons of phosphogypsum, a waste by-product of the Greek phosphate fertilizer industry, was disposed into an abandoned limestone quarry in Schistos former waste site, Piraeus (Greece). The quarry has been recently closed and remediated using geomembranes and thick soil cover with vegetation. A part of the deposited phosphogypsum has been exposed due to intense rainfall episodes leading to concerns about how could potentially released radioactivity affect the surrounding environment. This study seeks to assess the environmental impact of the phosphogypsum deposited in the Schistos quarry, using laboratory-based γ-ray spectrometry measurements and geographical information systems. Radioactivity concentrations were mapped onto spatial-data to yield a spatial-distribution of radioactivity in the area. The data indicate elevated (226)Ra concentrations in a specific area on the steep south-eastern cliff of the remediated waste site that comprises uncovered phosphogypsum and is known to be affected by local weather conditions. (226)Ra concentrations range from 162 to 629 Bq/kg, with an average activity being on the low side, compared to the global averages for phosphogypsum. Nevertheless, the low environmental risk may be minimized by remediating this area with geomembranes and thick soil cover with vegetation, a technique, which has worked successfully over the remainder of the remediated quarry. |

| Abstract | Greenhouse experiments were carried out to evaluate the effect of different soil-based countermeasures on radiocesium transfer to Medicago saliva (alfalfa) grown on artificially contaminated loamy-clayey soil. Various rates of potassium, ammonium, and Prussian Blue supplements were applied, and the uptake of radiocesium by control and treated alfalfa plants was monitored during four growth periods. Transfer factors ranging between 0.06 and 0.02 were determined for control plants. Application of potassium at rates higher than 0.1 meq per 100 g soil was found to suppress radiocesium uptake, the effect being more pronounced at increasing fertilization rates. On the contrary, soil treatment with ammonium enhanced the bio-accumulation of radiocesium, indicating that Cs+ ions, previously unavailable to plant roots, were released from soil particles. Prussian Blue supplements had practically no effect on soil-to-alfalfa transfer of the radionuclide. |

| Abstract | The nuclear magnetic moment of the ground state of (57)Cu(Iota(pi) = 3/2(-), T(1/2) = 196.3 ms) has been measured to be /mu((57)Cu)/ = (2.00 +/- 0.05)mu(N) using the beta-NMR technique. Together with the known magnetic moment of the mirror partner (57)Ni, the spin expectation value was extracted as <Sigmasigma(z)> = -0.078 +/- 0.13. This is the heaviest isospin mirror T = 1/2 pair above the (40)Ca region for which both ground state magnetic moments have been determined. The discrepancy between the present results and shell-model calculations in the full f p shell giving mu((57)Cu) approximately 2.4mu(N) and <Sigmasigma(z)> approximately 0.5 implies significant shell breaking at (56)Ni with the neutron number N = 28. |

| Abstract | Die natuerliche Radioaktivitaet in Phosphatduengemitteln, die im NW Griechenlands eingesetzt werden, wurde mittels Gammaspektroskopie gemessen. Die Radioaktivitaet wird hauptsaechlich durch Radium226 verursacht. Weiterhin wurden Radioaktivitaetsmessungen an Bodenproben durchgefuehrt und mit Ergebnissen unberuehrter Boeden verglichen. Radium226 gehoert zu der U238-Zerfallsreihe und ist der Vorgaenger von Radongas, Rn222. Die Radonkonzentrationen in Lagerhallen, in denen grosse Mengen von Duengemitteln aufbewahrt werden, wurde mittels CR-39 SSNTD gemessen. Die Radiumkonzentrationen in den Duengemitteln variierten zwischen 0 und 4584 Bq pro kg. Die Radonkonzentrationen in den Lagerhallen lagen zwischen 540 und 3320 Bq pro Kubikmeter. Die Ergebnisse werden aus der Sicht des Strahlenschutzes diskutiert. |

| Abstract | Spin polarization of 37K nuclei produced via single proton pickup from a 9Be target by a beam of 150 MeV/nucleon 36Ar has been observed. Positive spin polarization with magnitude (8.5+/-0.6)% was deduced near the peak of the 37K momentum distribution. The variation of the spin polarization as a function of outgoing 37K momentum is explained by a classical conservation model, as previously applied to describe the induced spin polarization observed for fragments produced in intermediate-energy heavy-ion reactions, with the condition that the picked-up proton has an average momentum equal to the Fermi momentum and is aligned along the incident beam direction. |

| Abstract | The effectiveness of Prussian Blue in reducing the radiocesium contamination in ovine tissues was investigated. Five ewes were fed 137Cs-contaminated wheat for 30 d. When the 137Cs concentration in milk had reached equilibrium, one animal, serving as the control, was slaughtered and the activity in its tissues was measured. Two ewes were offered daily 1 g of Prussian Blue labeled with 59Fe in the Fe(III) position, outside the complex anion. One week after the administration of Prussian Blue, these animals were slaughtered, 1 wk apart, and the level of 137Cs in their tissues was measured. Comparing the concentration of 137Cs in the blood and tissues of the Prussian Blue treated animals to the corresponding concentrations measured in the control, a considerable reduction in the radiocesium activity concentration is observed. However, 137Cs concentrations are maintained at non-zero (about 20%) values in the first 2 wk after the administration of Prussian Blue. This observation can be attributed to the fact that most of 137Cs binds to Prussian Blue in the animals' digestive tracts and the measured activity concentrations follow the elimination of cesium from tissues. Using a two-compartment mathematical model, we can predict the level of 137Cs in tissue, following the administration of Prussian Blue. Labeling Prussian Blue in the Fe(III)-position resulted in the measurement of a (2.4 +/- 0.02) % retention of Fe(III) in sheep. |
