Lead-210 is a naturally occurring radionuclide of great importance for environmental studies. Its vertical distribution in the soil, combined with that of 226Ra, may provide useful information on the radon released to the atmosphere in the region, due to soil radon exhalation, or radon carried by ground water. Previous research has shown that natural radioactivity levels – in...

An innovative brachytherapy treatment based on Re-188 has been recently developed for squamous cell carcinomas of the skin. The planning and delivering of the treatment requires an accurate knowledge of the source activity and thus proper calibration of activity meters. However, reference sources for calibration purposes are not always available, as in the case of short-lived...
The use of Monte Carlo methods for the set up of treatment planning systems (TPS) in radiotherapy applications is a current standard. The most advanced modeling techniques aim to directly link the output of CT scans to the patient specific model build up instead of standard phantoms and look up tables. This phase represents a critical step since even the most accurate segmentation and organ...
This talk reports on the HCAL-J hadron calorimeter, that we assemble at Jefferson Laboratory in Newport News, VA-US.
The main interest of JLAB [1] physics is the study of fundamental interactions and constituents of hadronic matter by a longitudinally polarized electron beam; in particular, the electromagnetic Form Factors of nucleons are studied using a continuous electron beam as a probe,...
A new Large-Acceptance Forward Angle Spectrometer (Super Bigbite Spectrometer-SBS [1]) is under development for the upcoming experiments in Hall A at the Thomas Jefferson National Accelerator Facility (Virginia-USA) [2], where a longitudinally polarized (up to 85%) electron beam up to 12 GeV energy is now available. The excellent beam intensity (up to 100 μA), combined with innovative...
The surging growth of exposure to Electromagnetic Fields (EMF) represents one of the main factors of people concern about negative biological effects generated by environmental stressors. The worldwide use of cellular phones has generated public concern about exposure to the microwave radiation associated with these phones. The probable biological effects due to the use of mobile phones can be...
The Radiochemistry group at Politecnico di Milano is active in several cutting-edge research topics in the areas of Radiochemistry and Radiation Chemistry. Thanks to the availability of the New Integrated Nuclear Laboratories at Campus Bovisa in Milano, the research group is able to develop education & training activities within the Master degree course in Nuclear Engineering and the Doctoral...
In Italy, that of “Radiochemist” is now an “endangered species”…
After the Referendum of 1987, which produced, in fact, the exit of Italy by the programs for the peaceful use of nuclear energy, the number of young people, students and researchers, interested in nuclear disciplines has declined more and more to the current critical situation.
On the other hand, the need to characterize, from...
This study reviews the unique experience of research in the water treatment applied in educational process.
The Faculty of Chemistry of the Belarusian State University (BSU) works in close contact with the Research Institute for Physical and Chemical Problems, which originally stemmed from the Faculty itself, but later separated. The experts of the Research Institute and Faculty of Chemistry...
Chemical dosimeters represent a promising instrument for treatment plan verification in radiotherapy. To achieve the required dependability in terms of sensitivity, accuracy, precision and temporal stability of measured dose distributions, it necessary to characterize how such parameters might be influenced by varying irradiation characteristics, to mimic the different scenarios that can be...
During the 2015/2016 moss survey, ninety-five (95) samples of Hypnum cupressiforme Hedw., were collected in the region of Northern Greece during the end of summer 2016, covering a regular grid of 30 km x 30 km. The samples collected from different altitudes, from 30 m to 1450 m above the mean sea level. The regions from where samples were collected were open regions in most of the sampling...
Within the development of Lead-cooled Fast Reactors, the chemical compatibility of lead with oxide fuels is still a little explored matter. The possibility to predict the effects of the chemical interaction among lead, steel and irradiated nuclear fuel as a consequence of a cladding failure event or a severe nuclear accident is of paramount importance to assess the safety of such nuclear...
Actinide recycling by the so-called Partitioning & Transmutation (P&T) strategy is considered worldwide, and particularly in several European countries, as one of the most promising strategies to reduce the inventory of radioactive waste and optimise the use of natural resources. In Europe, the research programs dedicated to hydrometallurgical separation of MA have been supported mostly by the...
The safe confinement of the nuclear waste coming from fuel reprocessing operations is one of the key points in the sustainable development of the nuclear fuel cycle and, in general, of nuclear energy.
Fluoride-containing radioactive wastes are generated during the pyrochemical reprocessing of spent nuclear fuels. They differ significantly from the wastes arising from hydrochemical processing,...
In the last decades, hundreds of nuclear reactors have been shut-down and have experienced decommissioning operations. This is also the case of L-54M Politecnico di Milano nuclear research reactor. Since shut-down in 1979, the plant has been managed according to deferred dismantling strategy. Following National and International well-established guidelines, several activities, such as spent...
The great properties of conventional synthetic plastics have allowed a wide range of applications. Packaging constitutes the larger market segment and, due to its specific function, it rapidly becomes waste that increasingly accumulates in the environment. Most of the conventional petrochemical-based plastics are not biodegradable and the production of biodegradable and bio-based plastics is...
The SEE (Single Event Effect) problematic in electronic components used in space industry is assessed using a Monte Carlo method. This work is focused on modelling two different structures of 18nm-transistors to simulate the transport of ionising particles through the components using C++’s toolkit Geant4. Single Event Transients (SET) are particular cases of SEE that can cause voltage spikes...

For all of us non-native speakers to learn English has been a challenge at a certain point in our lives. It is said that chemists, physicists, engineers, lawyers, philologists speak in a different language from the rest of society. The discovery of radioactivity a century ago opened up a new field “nuclear science”. Nowadays Nuclear English is the most demanding English not only for...
Radon is a natural radioactive gas derived from geologic materials and abundant in granitic areas. Indoor environment radon contamination can be induced by either outdoor air entering dwellings and radon contamination of water but the ionizing radiation from naturally occurring radioactive materials (NORM) present in building materials, should not be underestimated. Civil engineering students...
Degree Programmes Radiological Technology and Radiological Physics, taught at the Department of Dosimetry and Application of Ionizing Radiation at the Faculty of Nuclear Sciences and Physical Engineering of the CTU in Prague, are within the boundaries of both physics and medicine. As such, they must be accredited by the National Accreditation Bureau for Higher Education, but they are also...
This study deals with the initiative undertaken at the Belarusian State University (BSU) related to nuclear knowledge portal.
The International Atomic Energy Agency (IAEA) pays close attention to the problems of nuclear knowledge management. Every developed country with its own nuclear industry has to create and maintain a national portal of nuclear knowledge integrated into the global system...
Expertise in nuclear and radiochemistry (NRC) is of strategic relevance in order to maintain European nuclear operations. There are many applications that need NRC skills other than the more obvious context of nuclear power and assessment of disposal options for nuclear waste. This includes medical applications, such as radiologic diagnostics and therapy, but also dating in geology and...
