Human populations and natural ecosystems are bound to be exposed ionizing radiation from the deposition of artificial radionuclides resulting nuclear accidents, devices or radiological dispersive (“dirty bombs”). On other hand, Naturally Occurring Radioactive Material industries such as phosphate production uranium mining, contribute on site storage residuals with enhanced concentrations radionuclides. Therefore, in context European agreements concerning energy, namely Atomic Energy...
Radiological monitoring is fundamental for compliance with radiological protection policies in the aftermath of events, such as nuclear accidents, terrorism, and out-of-commission uranium mines. An effective strategy radiation to use detectors coupled Unmanned Aerial Vehicles (UAVs), enabling quicker surveillance large areas without involving need human presence target area. The main aim this study was formulate parameters a UAV flight preparation future field measurements using...
The high intensity and energy ISOLDE (HIE-ISOLDE) project is an upgrade to the existing facility at CERN. foreseen increase in nominal of primary proton beam aims increasing produced radioactive ion beams (RIBs). currently uses from proton-synchrotron booster with 1.4 GeV up 2 μA. After (final stage), HIE-ISOLDE supposed run 4 imposes constrains, radiation protection safety point view, experimental supply areas. Taking into account upgraded beam, a new assessment necessary. Special attention...

This work is related to the design of core eXperimental demonstration technological feasibility Transmutation in an Accelerator-Driven System (XT-ADS) facility framework EUROpean Research Programme for TRANSmutation High Level Nuclear Waste Accelerator Driven (EUROTRANS) project. The specifications proton accelerator XT-ADS are 600 MeV and up 3.5 mA beam energy current, respectively. impinges on a liquid target consisting lead-bismuth-eutectic mixture. state-of-the-art Monte Carlo code MCNPX...
ITER's Collective Thomson Scattering (CTS) system is a diagnostic instrument that will measure the plasma density and velocity through scattering of microwave radiation. Some key components CTS are quasioptical mirrors used to produce astigmatic beam patterns, which have impact on strength spatial resolution signal. The exposed neutron radiation, may alter mirror properties or deform its structure. These changes affect collection scattered radiation consequently decrease quality...
Given the very short range (micrometers to few nanometers) of Auger electrons (AE), Coster-Kronig (CK) and internal conversion (IC) emitted by several radionuclides, they are nowadays considered as promising solutions for molecular targeted radiotherapy.The aforementioned can locally deposit their energy near radionuclide decay site, reducing radiotoxicity surrounding healthy tissues in this way. 125I (T1/2=59 days, 23 per decay, ĒAuger= 520 eV) 99m Tc (T1/2=6 h, 4.4 ĒAuger=213 two...

The EURopean Isotope Separation On-Line Radioactive Ion Beam (EURISOL) project aims at building a facility to produce radioactive ion beams with intensities two three orders of magnitude higher than those presently available. A 4-MW (1-GeV, 4-mA) proton beam hits liquid mercury converter, generating, by spallation reactions, high neutron fluxes that induce fission in surrounding fissile targets. In this work, Monte Carlo calculations dose rate and activation were carried out identify the...
Double-differential cross section (DDX) data on the neutron-induced emission of light charged particles are required for assessing risk secondary tumors in particle radiation therapy. There only very few DDX available discrete neutron energies close to and above 100 MeV carbon. A measurement carbon is planned at continuous from 20 200 with detector telescopes n_TOF (CERN). Several development criteria challenges reported such as coincidence timing electromagnetic oscillations high energy...
