A PM10 chemically characterized nation-wide dataset for Italy. Geographical influence on urban air pollution and source apportionment.

Urban textures of the Italian cities are peculiarly shaped by the local geography generating similarities among cities placed in different regions but comparable topographical districts. This suggested the following scientific question: can different topographies generate significant differences on the PM chemical composition at Italian urban sites that share similar geography despite being in different regions? To investigate whether such communalities can be found and are applicable at Country-scale, we propose here a novel methodological approach. A dataset comprising season-averages of PM mass concentration and chemical composition data was built, covering the decade 2005-2016 and referring to urban sites only (21 cities).

Fast and non-destructive neutron activation analysis for simultaneous determination of TiO and SiO in sunscreens with attention to regulatory and research issues.

A new instrumental neutron activation analysis (INAA) for the simultaneous determination of titanium (TiO) and silica (SiO) dioxide as UV-filters in sunscreens is described. Samples are encapsulated, neutron irradiated (30 s) and after a suitable decay (3 min), the induced Ti (T = 5.76 min) and Al (T = 6.

Decommissioning procedure and induced activation levels, calculations and measurements in an 18 MeV medical cyclotron.

The present article describes the decommissioning of a self-shielded 18 MeV medical cyclotron IBA Cyclone 18/9 after 14 years of operation. A Monte Carlo simulation of the possible nuclear reactions was performed in order to plan the decommissioning activities. During the cyclotron dismantling, the activities of the cyclotron components, concrete wall and floor samples were measured.
