Atoms for Peace

Nanoparticles of a BaSO4:Eu phosphor with a particle size of
around 40 nm have been irradiated by 48 MeV 7Li3+, 75 MeV C6+ and
90 MeV O7+ ion beams at the fluence range of 1 × l09–1 × 1013 ions/cm2.
The thermoluminescence (TL) glow curves of the irradiated samples were
recorded and studied. The microcrystalline form of this sample is included in
the study with the aim of reporting a comparative measurement. The TL results
of this material in its nano- and microforms exposed to the gamma rays of 60Co
are also included and investigated in more detail. It is observed that the glow
curves of the nanomaterial exposed to these ions are similar to that exposed to
gamma rays, with a dosimetric peak at 462 K beside a smaller one at 503 K,
while those of the microcrystalline sample exposed to both ion beams and
gamma rays have their prominent peak at 503 K beside a smaller one at 462 K.
The observed TL sensitivity of the nanocrystalline material is less than
that of the microcrystalline sample at low fluences/doses, while it is more at
higher fluences/doses. This nanophosphor exhibits a linear/sublinear TL
response to energetic ions and gamma radiation over a very wide range of
exposures, which is much wider compared to that of its microcrystalline
counterpart. This makes the nanostructural form of BaSO4:Eu useful to
estimate the high doses of different ionising radiations that are in use for
radiotherapy or food/seed irradiation.

Assessment of the dosimetric index from IMRT and RapidArc plan for oropharyngeal cancer with simultaneous integrated boost technique in combination with EUD-based NTCP and TCP radiobiological models.

After a short review of radioactive waste origins and inventories in Italy, the paper deals with the current major challenges that Italy has to cope with to pursue its radioactive waste sustainable management and safe disposal. Site restoration by Sogin of dismissed nuclear installations is part of the waste management challenge. The importance of assuring the highest levels of safety culture among the employees and an overall manpower, adequate both in number and qualification according to the best international good practices, is underlined and included in the largest effort of the knowledge management project. Sogin is coping with the above challenges also with the Italian School on Radioprotection, Safety and Environment, a unique centre of know-how and know-why transfer in Italy.

Radioactive waste management in Italy

The International Brotherhood of Electrical Workers (IBEW) represents workers, many who work in the utility and power generation industries. The IBEW has been and continues to be a vocal supporter of the expansion of nuclear power generation in the USA. Five years ago, there was a general expectation that nuclear capacity would expand greatly. It did not, and in part the absence of more new nuclear construction is the natural outcome of a misguided energy market regulation system. We close with a set of priorities for rebuilding the energy regulatory scheme that would benefit our members and ratepayers and would, at the same time, lead to and require an expansion of nuclear power. The article describes the state of nuclear power in the USA today, the IBEW’s role in the utility industry and nuclear power generation; the IBEW’s priorities for the US energy market and why those priorities lead the IBEW to call for the expansion of nuclear power in the USA.

Starting from a description of the current situation, which sees Italy outside the nuclear producers, the paper describes the different realities that are still working on nuclear energy and its different facets, illustrating Italian enterprises’ and trade unions’ role in a future perspective.
