The Synchrotron SOLEIL, the French 3rd generation synchrotron light source, will be upgraded to a 4th generation ring, based on multi-bend achromat lattice to achieve a very low emittance electron beam (~80 pm.rad) and a much more brilliant and coherent synchrotron light source.
To achieve this and allow the filling and top-up operation of SOLEIL II new storage ring, the injector, made of a...

Borated concretes are often selected as combined gamma-neutron shielding material for particle accelerators or nuclear plants. Accurate knowledge of the boron content in these materials is crucial for guaranteeing a realistic shielding design. Therefore, the concrete industry adopts specific QA/QC techniques, such as the prompt gamma activation analysis (PGAA), usually performed at research...

A new type of neutron monitor with extended energy range, called NECH, was recently put on the market. Its nominal properties are highly attractive for radiation protection around nuclear or particle accelerator facilities: it responds up to GeV with H*(10)-like curve, it is nearly isotropic, and its sensitivity is nearly double with respect to common commercial devices. The NECH was tested at...

Electronic personal dosemeters (EPD) are powerful tools for achieving ALARA (As Low As Reasonably Achievable) objectives in operational radiation protection. These offer real-time reading, time-resolved dose recording, alarm threshold settings and visible/audible alarms to prevent accidental exposures. EPD for photons are well developed and their performances usually comply with relevant...

The last nuclear power plants in Germany have been shut down in spring 2023 and are in the process of decommissioning. For this process, it is necessary to estimate the different waste quantities and qualities, e.g. between activated, contaminated and material which can be released for further use. Part of the contamination due to deposits of radioactive particles on the surface can be removed...

The TS1 spallation target operated at ISIS between 2014 and 2019 for the production of neutrons by high energy protons (700-800 MeV) is made of 12 tungsten plates cladded with tantalum and water-cooled. Residual radioactive nuclei can be produced in the target either as a direct product of the spallation process or as a result of secondary low energy neutron absorption.

Gamma dose rates in the Gy/h to kGy/h range can be found at particle accelerators in hot points such as targets, bending magnets or interaction points. As these points constitute "source terms" in shielding design, a device to correctly measure these doses is desirable. Although a number of passive dosimetry techniques have been established in the past, very few or no direct-reading dosimeters...

Plume dispersion into the atmosphere of radioactive cloud emitted by a source can be affected by the presence of buildings and obstacles modifying the velocity and the spatial distribution fields respect to the classical Gaussian Plume Model. The Gaussian Plume Model (GPM) is often used to assess the submersion dose resulting from an emission stack. The dispersion of the radioactive cloud is...
