The detection of solar neutrinos by means of a liquid scintillator requires very low levels of radioactivity throughout the whole active volume. The selection of clean detector materials and the purification of the scintillator are necessary, but not sufficient conditions. It is also crucial that during the filling operations the scintillator is not contaminated, either by air or by getting in contact with dirty surfaces. This paper describes the procedures which we adopted to minimize these risks and achieve very good levels of radio-purity which we finally got in Borexino.

AbstractThis article presents the results of scientific analyses on a selection of sherds associated with two kilns from the site of Kinet Höyük (Hatay). The kilns are dated to the eighth century BC and the end of the seventh century BC. In between these two periods, archaeological evidence suggests a period of occupation by the Neo-Assyrians. The present study assesses the impact of this occupation on the pottery industry at the site using a combined approach of thin section and neutron activation analyses. The results of these analyses additionally allow for a new classification system of local wares.

Epithermal neutron activation analysis is examined using a SLOWPOKE nuclear reactor. Data are given for 69 elements using cadmium and boron shielding. Cadmium ratios calculated from literature values of resonance integrals are compared with experimental values. All elements except cadmium are shielded more effectively by boron. Advantage factors for a selection of elements under cadmium, natural boron, and enriched boron shields are given. Boron shields are of particular practical value for rapid instrumental analysis.
